Systems
VAV SystemsThere are two primary types of VAV systems—single-duct and dual-duct.
Single-Duct SystemsSingle-duct systems include one supply fan and a single supply duct that is attachedto each zone. The supply fan delivers cooled air to the VAV zones in variablevolumes, depending upon the cooling requirements. The supply fan is usuallydesigned to modulate airflow delivered to the VAV zones.
Many VAV zones require heating as well as cooling. The supply air-handling unitprovides either no heat (cooling only), morning warm-up heat or occupied(changeover) heat. In addition, heat may be provided at any individual VAV zone(within the zone or within the VAV terminal) by reheating cool air provided by thecentral air handler.
No HeatCentral Cooling Only—In some systems, the central air handler provides onlycooling and ventilation during zone occupied periods. The supply air is maintained ata constant temperature and the supply airflow is modulated to match the VAVairflow rate with the zone cooling requirements.
Central HeatCentral Heat for Morning Warm-up—Many buildings cool down during the night. Tobe at a comfortable temperature in the morning when the building is againoccupied, heat must be added to the spaces. Heat provided by the central airhandler for morning warm-up is supplied at constant air volume to the zones, priorto the time of occupancy. During the morning warm-up period, the VAV terminalunits must open to allow heated air to flow into the zones. In most instances verylittle additional heat is needed once the building is occupied.

Central Occupied Heating-Changeover—Somebuildings use the same air handler to provide bothoccupied cooling and occupied heating. This iscommonly referred to as a changeover system. Thesystem changes between heating and coolingdepending on the need of the zones on the system.In a changeover system, the operation of the VAVterminal units must also change over, opening toprovide heat in the heating mode and opening toprovide cooling in the cooling mode. Trane's mainproduct in this type of application is called VariTrac™.VariTrane products can also be used in thesesystems. (These types of systems are beyond thescope of this manual and are discussed in detail inthe VariTrac II Manual, VAV-PRC003-EN.)

when the cooling load is lower than theminimum cooling capacity of the VAVterminal unit. Heat is added directly tothe zone while cool supply air continuesto enter the zone at a minimum rate forzone ventilation.
Terminal Reheat—In some zones of asingle-duct VAV system, a minimumflow of cool supply air is reheated at theterminal unit before entering the zone.Terminal reheat can be provided byelectrical resistance heaters or by hotwater coils.
Parallel Fan-Powered Heat—In somezones of a single-duct VAV system, coolsupply air at minimum flow is mixedwith warm plenum air before enteringthe zone at a constant flow rate. A fan inthe terminal unit, in parallel with thecentral fan, draws air from the plenumwhenever the zone requires heat.
Series Fan-Powered Heat—In somezones of a single-duct VAV system, theairflow to the zone is held constant,during both heating and cooling, by aterminal unit fan that is in series with thecentral fan. The terminal unit fan runscontinuously. When the zone requiresheat, cool supply air at minimum flow ismixed with warm, return plenum airbefore entering the zone.
Dual-Duct SystemsDual-duct systems have either one ortwo supply fans and two duct systems.One duct system carries heated air andthe other duct system carries cooled air.Heated air and cooled air are modulatedand/or mixed at each zone in the properproportions to control zone temperature.Terminal reheat is not required in a dual-duct system.

VariTrane VAV Terminal UnitsThe function of the VariTrane terminalunit in a VAV control zone is to vary thevolumetric airflow rate to the zone.VariTrane units are available with eithermicroprocessor-based DDC controls orpneumatic or analog electronic controls.Factory-installed controls are availablewith all types of terminal units.
VariTrane VAVTerminal Unit Types
Single-DuctSingle-duct terminal units control thevolumetric flow of supply air to thespace to maintain the zone temperatureat setpoint. These units are generallyapplied in cooling-only VAV zones thatrequire no heat during occupied hours. Iflocal zone heat is necessary it can beprovided either remotely (for example,perimeter heat) or by terminal reheat(either electric or hot water coils).

Dual-DuctDual-duct terminal units are used in aspecial type of air distribution systemwhere the main system has both warmair and cold air separately ducted toeach terminal unit. The flow of bothwarm air and cool air is modulated,delivering air to the VAV zone atvariable air volumes as well as variabletemperatures. Since full capacityoccupied heating is always available,control of additional local heat isnot provided.
Dual-Duct Terminal Unit
Parallel Fan-PoweredParallel fan-powered units arecommonly used in VAV zones whichrequire some degree of heat duringoccupied hours—when the primarysupply air is cool. The terminal unit fan isin parallel with the central unit fan; noprimary air from the central fan passesthrough the terminal unit fan. Theterminal unit fan draws air from thespace return plenum.
When no heat is needed, the localparallel fan is off and a backdraftdamper on the fan’s discharge is closedto prevent cool air entry into the returnplenum. When cool airflow to the VAVzone is at a minimum and the zonetemperature drops below setpoint, thelocal parallel fan is turned on and thebackdraft damper opens. A constantvolume of air is delivered to the zonebecause the fan delivers a constantvolume of warm plenum air which ismixed with cool primary air at aminimum flow. Remote heat orterminal reheat can provide additionallocal heating.

Systems
Series Fan-PoweredSeries fan-powered terminal units areused commonly in VAV zones that notonly require heat during occupiedhours, but also desire constant airvolume delivery. The terminal unit fanis in series with the central fan. Primaryair from the central fan always passesthrough the terminal unit fan.
The local series fan within the terminalunit operates whenever the unit is inthe occupied mode. The volume of airdelivered to the VAV zone is constant,but the temperature of the delivered airvaries. As the zone requires lesscooling, the primary air damper closes.As the primary air damper closes, theair mixture supplied to the zonecontains less cool air and more warmplenum air. Remote heat or terminalreheat can provide additional localheating.
Series fan-powered terminal units arealso useful in low supply airtemperature systems, since theterminal unit fan can be sized so thatwarm plenum air is always mixed withlow temperature supply air. This raisesthe supply air temperature to anacceptable distribution level andreduces condensation potential.
Series Fan-Powered Unit Cooling Only
Low-Height Fan-PoweredLow-height fan-powered terminal unitsare a slightly modified version of a fan-powered terminal unit. As its namesuggests, the low-height fan-poweredunit has a shorter height dimension toaccommodate applications whereceiling space is limited. To shorten theheight dimension, different terminalunit fans are used from those thatwould be used in a correspondingseries or parallel terminal unit.
For low-height units with the smallerfan size (size 08), a single low-profilefan is used. Low-height units withlarger fan sizes (size 09 or 10) use twolow-profile fans. Each fan operates off aseparate motor. The fans still remain inseries or parallel with the primarysystem central fan. Low acoustic levelsare much more challenging in theselow ceiling space applications.
The operation of the low-heightterminal unit is exactly the same asthat of a series or parallel terminal unit.As with the other fan-poweredterminal units, additional local heatingcan be provided by remote heat orterminal reheat.

Parallel vs.Series
Fan-Powered versus Single-Duct VAV Terminal UnitsIn many climates, fan-poweredsystems are a lower operating costalternative than single-duct systems.The energy inefficiencies inherent inreheating cold primary air can beeliminated with a key designcharacteristic of fan-powered terminalunits, plenum air heating. Heating withwarmer plenum air allows for recoveryof heat from lighting and other heatsources in the building.
Comparison of Parallel andSeries ModelsOnce it has been determined that afan-powered system is to be specified,the designer must decide betweenparallel and series configurations. Eachmodel carries its own characteristics of
delivered airflow, energy consumption,and acoustics. For the end user, thedesigner might consider three goals: acomfortable and productive tenantenvironment, acceptable installed cost,and low operating costs.
Parallel and series fan-poweredterminal units offer specific advantagesfor particular applications. Thefollowing table compares the keysimilarities and differences betweenthe models that the designer shouldconsider in performing an engineeringanalysis.
Typical Application ofParallel Units:Parallel intermittent fan-poweredterminal units are very common inperimeter zones or buildings whereloads vary during occupied hours.Core zones, which maintain a more
constant cooling requirement, arebetter suited for variable airflow by useof single-duct units. Typical jobsrequiring parallel fan-powered unitswill also use single-duct units.
Typical Application ofSeries Units:Applications requiring constant airmovement or blending utilize seriesconstant fan-powered terminal units.Conference rooms, laboratories, andlobbies are common applications.Because the series fan also adds to thesystem external static pressure, officebuildings take advantage of this designfeature and down size main airhandling equipment. Finally, seriesterminals are used in low-temperatureair systems to temper cold primary airwith warm plenum air and deliver it tothe zone.

Low-Temperature Air SystemBenefits of Low-Temperature AirThe benefits of low-temperature airsystems include reduced first cost,reduced operating cost and increasedrevenue potential. Since low-temperature air transports moreenergy per cubic foot, smaller fans andducts can be used. An EarthWise™system takes that a step farther andincludes optimizing the waterside ofthe HVAC system as well with low flowrates through the chilled water andcondenser loops.
Since low-temperature water cantransport more thermal energy pergallon, smaller pumps, pipes, andvalves can be used. Smaller HVACequipment consumes less energy soboth electrical demand andconsumption are lowered, reducingoperating costs. The amount ofrevenue generated by a commercialbuilding is related to the amount andquality of rental floor space. Theamount of rental floor space isincreased in a low-temperature airsystem, since air handlers, riser ducts,and equipment rooms are smaller.Since smaller ducts reduce therequired ceiling plenum, additionalfloors may be included withoutincreasing building height.
The concept of the EarthWise system isto deliver superior comfort and be lessexpense to install and operate. Themethod to do this involves bothwaterside optimization and airsideoptimization. The waterside isoptimized using techniques of lowwater flow through the evaporator andcondenser of the chiller as well asusing chiller-tower optimization controlstrategies. For more information on thewaterside of the EarthWise system,contact your local Trane representativeor visit www.trane.com.
Low Temperature Air System Layout
For the airside system, the savings areseen using a combination of lower airtemperature and several controlstrategies using the ability of the VAVunit to communicate information.
System OperationA low-temperature air system could bedone with chilled water or directexpansion equipment. A chilled watersystem includes a chiller plant, VAV airhandlers, and series or parallel fan-powered VAV terminal units. The VAVair handlers use cold water, typicallyaround 40°F (4.4°C), from the chillerplant, to cool the supply air to 45–50°F(7.2–10°C). The volume of supply air isdetermined by the airflow needs of theVAV terminal units. A direct-expansionsystem would include a VAV airhandler or rooftop with series orparallel fan-powered VAV terminalunits. The supply air would be cooledto 48–52°F (8.9–11.1°C).
The VAV terminal units include aparallel or series fan with the central airhandler or rooftop fan. The terminalunit fan operates continuously, mixing45-50°F (7.2–10°C) supply air with warmplenum air, to provide 50–55°F(10–12.8°C) cooling air to the occupiedspace at design conditions. As thecooling load in the space decreases,the VAV terminal air valve closes toreduce the flow of cold supply air andincrease the flow of warm plenum airin the case of series terminal units. Thetemperature of air supplied to thespace rises, but the volume flow rate tothe space is constant for the series unit.
Considerations for VAV productsTo achieve the maximum benefit fromthe low-temperature air system, thereare several considerations that must beaddressed for the VAV units.
InsulationThe units must be insulated to insurethat no condensation occurs on theunits. How much insulation is needed?Trane has tested its insulation with thegoal of developing a thermalresistance ratio for each type ofinsulation. The thermal resistance (TR)ratio is discussed in the section relatedto insulation. The TR ratio can be used,along with the properties of theinsulation and the system operatingconditions to determine the necessaryinsulation thickness required.
In the low-temperature air system withfan-powered units, the ducts anddiffusers downstream from theterminal unit handle air that is 55°F(12.8°C) or warmer. Therefore,condensation considerations are nodifferent from conventional systems.Linear slot diffusers are recommendedto take advantage of the Coanda effectdescribed in the Diffusers section laterin the catalog.
Terminal unit surfaces that aretraditionally not insulated—electric andhot water reheat coils and the primaryair inlet for example—should bethoroughly field-insulated.

LeakageWhen the terminal unit fan is off, theair valve will close, and not leak. Ductsupstream of the terminal unit mustalso be thoroughly insulated andconstructed for very low leakage.
Duct and terminal unit insulation canbe internal or external. However,internal insulation has hidden thermalleaks at joints and seams. These areasmust be located and insulatedexternally to avoid condensation. Onthe other hand, external insulationallows a complete, uniformthermal seal.
Minimum settings and IAQIndoor air quality is usually best whena specific quantity of outsideventilation air reaches each buildingoccupant. Maintaining a minimumventilation rate is a challenge in anyVAV system, since the amount ofsupply air that reaches a particularspace decreases as the cooling loaddecreases. To insure that a minimumamount of supply air reaches the spaceat all times, a minimum flow setting onthe terminal unit is used. In low-temperature air systems, when thespace needs heating, this minimumflow setting results in increasedheating load. Therefore, it is importantto include the additional load imposedby the cold supply air when calculatingheating loads. Reheat may be requiredsince the ventilation values areabsolute requirements and notpercentage of total airflowrequirements.
EarthWise or Low-Temperature AirDistribution Design Considerationswith Parallel Fan-powered TerminalUnitsThe parallel fan-powered unit needs tobe set up to run continuously ratherthan intermittently. Since it is inparallel, the airflow required by the fandoes not need to be as much as theseries unit. Getting the parallel unit tooperate continuously will take someminor control changes.
The parallel fan should be largeenough to temper the design coolingairflow at 45–50°F to 50–55°F (7.2–10°Cto 10–12.8°C). For instance, if thedesignc cooling airflow is 1000 cfm at55°F (472 L/s at 12.8°C), you will need781 cfm of 48°F (368 L/s of 8.9°C)supply air and 219 cfm of 80°F (103 L/sof 26.7°C) plenum air. The parallel fancan be sized for the 219 cfm (103 L/s)rather than the total room airflow.
The fan airflow plus the minimumprimary airflow must be checked withthe minimum airflow of the diffusers toinsure that dumping doesn’t occur. Ifthat is a concern, the minimum couldbe adjusted up or the fan airflow couldbe adjusted up.
As the valve closes, the downstreamstatic pressure will decrease becausethe pressure is related to the airflow.The fan will supply more air at thevalve minimum condition than atdesign due to the decreased staticpressure. This should be aconsideration when calculating howmuch airflow would occur at theminimum valve plus fan airflowcondition. The new fan airflow wouldbe found by looking at a fan curve atthe new SP point. The new SP canbe calculated:
The following table can be used todetermine what percentage of the totalairflow should come from the fan totemper the supply air, assuming 80°F(26.7°C) plenum air.
If anything other than 80°F (26.7°C),the following equation can be used tocalculate the percentage:
SupplyTemperature =(%*primarytemperature) + (1-%)*plenumtemperature
downstream of the VAV terminal unit,the system designer will have someconcerns related to condensation ondiffusers and other low-pressureductwork accessories. For instance, ifthe occupied space must receive 1000cfm of 55°F (472 L/s at 12.8°C) air tosatisfy to design cooling load, 715 cfmmust be 45°F (337 L/s must be at 7.2°C)supply air and 285 cfm must be 80°F(135 L/s must be 26.7°C) plenum air.Therefore, the series fan-poweredterminal must be sized to have the airvalve deliver 715 cfm (337 L/s) ofsupply air at design conditions, but thefan must be sized to deliver 1000 cfm(472 L/s).
Airside System FactorsA couple of system related factorsshould be noted as they apply tocondensation. The first is theadvantage the colder primary air hasfrom a humidity standpoint. As notedin the description above, the low-temperature system operates at spacerelative humidity of 30–45% while astandard system operates at spacerelative humidity of 50–60%. The drierzone air means that the plenum airreturning to the series terminal unit willalso be drier and, therefore, less of a
problem withcondensation.
The secondcondensation factor tonote is related tosystems that shut downin the evening. Manypeople believe that
immediately sending low-temperatureprimary air to these boxes that havebeen off for some time will cause ashock to the system and may causecondensation problems at startup. Thesolution to this has been the advent ofgradual pull-down or “soft start”systems. In this type of system, theprimary air temperature is higher oninitial startup (typically 55°F(12.8°C))and then gradually reduced to thenormal operating point over the next30 to 60 minutes.
Low-Temperature Air DistributionDesign Considerations withSeries Fan-powered TerminalUnitsThe VAV terminal unit includes afan that operates continuously.The series fan should be largeenough to insure that the mixtureof cold supply air and warmplenum air is 50–55°F (10–12.8°C)at design cooling flow conditions.In these types of systems, it is agood design practice to developthe system based upon 55°F(12.8°C) air being provided to thespace from the fan-poweredterminal unit.

Energy Savings &System Control
Electrically CommutatedMotor (ECM)
Fan-Pressure OptimizationWith Trane's Integrated ComfortSystem, the information from VAVterminal unit can be used for otherenergy-saving strategies. Fan-pressureoptimization is the concept of reducingthe supply fan energy usage based onthe position of the terminal unitdampers.
The control system allows thisscenario. The system controls poll theVAV units for the damper position oneach unit. The supply fan is modulateduntil the most wide-open damper isbetween 85% and 95% open. Thecorrect airflow is still being sent to thezones since the controls of the VAVunits are pressure-independent, andthe fan modulates to an optimal speedand duct static pressure which resultsin fan energy savings.
The ECM gives an additional energy-saving option to the system designer.Some of the advantages of the motorinclude high efficiency, quiet operation,short payback, and easy installation.There are several considerations thatneed to be addressed when decidingwhether to use these motors or not.The primary benefit may be seen asincreased efficiency.
Operating Hours—The added cost ofan ECM can be offset more quickly inapplications which require a relativelyhigh number of hours of operation.However, if a space does not requireextensive running time for the unit fan,then it may not be a good candidatefor this type of motor based solely onpayback. Therefore, the decision aboutusing the ECM may be based on otherbenefits, depending on the needs ofthe customer.
Airflow Flexibility—The ECM allows agreater airflow range per fan size. If aspace is going to change uses and loadcomponents frequently, the ability tochange supply airflow with the ECMwithout changing units will be abenefit.
Airflow Balancing—The ability of theECM motor to self-balance to anairflow regardless of pressure can bean asset when trying to air balance ajob. This will help eliminate additionaldampers or changes to downstreamductwork to ensure proper airflow. Formore information, please contact yourlocal Trane sales engineer.
Ventilation ResetVentilation reset is a control strategythat enables a building to bring in anappropriate amount of ventilation airper ASHRAE Standard 62.1. The basisfor the strategy is measuring airflow ateach zone and communicating back tothe air handler how much ventilation airis needed based on the 6-1 equation ofthe standard.
This strategy continually monitors thezones and minimizes the amount ofventilation air, which maximizes theenergy efficiency of the system. Thisinsures that the right amount of air isbrought in at all times and can bedocumented. The Trane Company hasintegrated this control ability into theVAV controls, air-handler controls, andbuilding controls.

Agency Certifications
There are numerous regulations andstandards in the industry that determinethe construction and performanceparameters for VAV terminal units.Some of the more important of thosestandards and regulations are listedbelow, along with a brief description ofwhat each one addresses.
American Society of Heating,Refrigerating and Air-conditioningEngineers (ASHRAE) - 41.1
ASHRAE - 41.2
ASHRAE - 41.3These standards specify methods fortemperature measurement (41.1),laboratory airflow measurement (41.2),and pressure measurement (41.3). Whilenone of these standards specificallydiscusses VAV air terminals, theydiscuss topics that are aspects ofterminal box systems. Therefore, someengineers will include these standardsin their specifications as a primer onaccepted measurement techniques.
ASHRAE - 62This standard specifies the minimumventilation rates and indoor air qualitythat are acceptable for occupied spaces.
ASHRAE - 111This standard calls out procedures to befollowed for testing and balancingHVAC systems. It includes descriptionsof the equipment used, proceduresfollowed, and field changes that mustbe made when a system is balanced.
Air Conditioning and RefrigerationInstitute (ARI)
ARI 880 - 1998This standard sets forth classifications,performance testing requirements, andtest results reporting requirements forair terminal units. The standardcontains very detailed procedures thatare to be followed for the testing andcertification program associated withthis standard. This is one of the mostcommonly referenced standards in theVAV terminal unit industry. The ARI-880certification program is designed topolice the accuracy of documentedperformance for terminal units. Thecertification program requires asampling of at least four units be testedannually. The tested units are chosen atrandom by ARI and sent to anindependent laboratory for the testing.The performance is tested at onespecific operating condition. Theoperating characteristics tested includedischarge and radiated sound power(for the damper and, in the case of fan-powered boxes, the fan), wide-opendamper pressure drop, and fan motoramp draw. VariTrane terminal unitsare certified according to ARI-880.ARI 885 - 1998This document provides a procedureto estimate sound pressure levels in anoccupied space. The standard accountsfor the amount of sound pressure inthe space due to the VAV air terminal,diffusers and their connecting lowpressure ductwork. While soundgenerated from the central system fanand ductwork may be a significantfactor in determining the soundpressure level in the room, thisstandard does not address thosefactors. It focuses solely on the VAVterminal and items downstream of it.This standard is related to ARI-880 byusing sound power determined usingARI-880 methodology as a startingpoint for the ARI-885 procedure.
Underwriter’s Laboratory (UL) 1995Underwriter’s Laboratory is anindependent testing agency thatexamines products and determines ifthose products meet safetyrequirements. Equipmentmanufacturers strive to meet ULguidelines and obtain listing andclassifications for their productsbecause customers recognize ULapproval as a measure of a safelydesigned product. VariTrane VAV airterminals are listed per UL-1995,Heating and Cooling Equipment.The terminals are listed as anentire assembly.
National Fire Protection Association(NFPA) 70This standard is also known as theNational Electrical Code (NEC). TheCode gives standards for installation ofwiring and electrical equipment formost types of commercial andresidential buildings. It is often referredto in VAV air terminal specificationswhen fan-powered boxes, electric heator electric controls are included.
NFPA 90AThis standard does not speak directlyto VAV air terminals but does discusscentral system considerationspertaining to a fire and/or smokecondition. The standard discussessafety requirements in design andconstruction that should be followed tokeep the air-handling system fromspreading a fire or smoke. Thestandard specifies practices that areintended to stop fire and smoke fromspreading through a duct system, keepthe fire-resistive properties of certainbuilding structures (fire walls, etc.)intact, and minimize fire ignitionsources and combustible materials.

ControlTypes
Control TypesVAV terminal units are available withmany different options. These optionsfall into three main categories ofcontrols: direct digital (DDC),pneumatic, and analog electronic. Allof these control types can be used toperform the same basic unit controlfunctions, yet differences exist inaccuracy of performance, versatility,installed cost, operating cost, andmaintenance cost.
Disadvantages:
Versatility—The communicationsprotocol between controllers will bedifferent from one controllermanufacturer to another.
Installed Cost—DDC controls are themost expensive of the three controltypes.
Operating and Maintenance Costs—Building personnel must be trained tooperate and maintain the system.
Operating and Maintenance Costs—Diagnostic capability for analogelectronics is not available.
Pneumatic control systems usecompressed air through simplemechanical control devices, such asdiaphragms, springs, and levers tochange an output in response to achange in a monitored variable. WithVAV terminal units, the output istypically a primary airflow and themonitored variable is zone temperature.
Benefits:
Performance—Pneumatic controls are aproven technology that is effective andhas a long life cycle.
Installed Cost—When a source ofcompressed air exists at the facility,pneumatics generally have a lowerinstalled cost than other types ofcontrols when only a basic functionalityis required.
Operating and Maintenance Costs—Pneumatics are still the most familiarcontrol technology to many buildingdesigners and maintenance people.
Large Installed Base—Pneumaticsystems are very common in existingbuildings. This eliminates the need topurchase the most expensive piece ofequipment in a pneumatic controlsystem—the control air compressor.Extensions to existing pneumaticsystems are generally very simple andextremely cost-effective.
Disadvantages:
Performance—Pneumatic controlsprovide proportional-only control forVAV terminal unit systems. This controlscheme is less accurate than the moreadvanced control schemes. Impropercalibration of pneumatic controls leadsto poor energy utilization.
Versatility—A central pneumatic controlsystem, where each of the control zonescan be monitored and adjusted from aremote location, is extremely costly toconfigure and to modify.
Operating and Maintenance Costs—Pneumatics easily drift and requireconstant upkeep and scheduledmaintenance. Diagnostic capability forpneumatics is not available. A maincompressor which is not maintainedand becomes contaminated with oil orwater can pump those contaminantsinto the compressed-air-distributionsystem. This may require costly cleaningof the system and a possiblereplacement of system components.
Direct digital control (DDC)systems became available asadvances in computer technologymade small microprocessorsavailable and affordable. Much of thehardware in DDC systems is similarto analog electronic systems. Theprimary difference is that DDCcontrollers allow system integration,remote monitoring, and adjustment.The microprocessor is programmedusing software that gives thecontroller a higher level of capabilitythan either the pneumatic or analogelectronic options.
Benefits:
Performance—DDC controls offer PIcontrol capability. A PI controlscheme is the most accurate andrepeatable control scheme availablein the VAV terminal unit industry.
Versatility—DDC controls acceptssoftware commands to determinehow its outputs will be controlled.When a control sequence must bemodified, making changes to thesoftware instructions is easier andquicker than changing hardware.
Operating and Maintenance Costs—DDC controls can be networkedtogether to provide system-controlstrategies for energy savings.Multiple controllers can be easilymonitored and adjusted from aremote location. DDC controls alsohave system and individualdiagnostic capability.
Analog electronic control systemsbegan to be used in the 1970s and1980s. Cost effective and reliabletransistors, resistors, relays, and triacs(electronic relays) allowed analogelectronics to become a substitute forpneumatic controls. Analog electroniccontrols use varying voltage signals tochange an output in response to amonitored variable.
Benefits:
Performance—Analog electroniccontrols are a basic technology thathas good repeatability.
Operating and Maintenance Costs—Analog electronics have minimal driftand therefore require much lessrecalibration than pneumatics.
Ease of Use—Analog electroniccontrols can be modified using tools asbasic as a screwdriver and a voltmeter.Knowledge and availability of apersonal computer is not required.
Disadvantages:
Performance—Analog electronicsprovide proportional-only control forVAV terminal unit systems. This controlscheme is less accurate than the moreadvanced control schemes.
Installed Cost—Analog electronicshave a higher installed cost thanpneumatic controls for systems withbasic functions.

ControlTypes
DDC Controls Basic InformationDDC controls have become theindustry standard for VAV terminal unitcontrol systems. DDC systems useelectronic field devices such as a flowtransducer, a primary air modulatingdamper, and an electronic thermostat.These field devices report softwareinstructions of how the outputs arepositioned in relation to the inputs to acontroller. The VariTrane system uses aprimary air valve and flow transducerfor both DDC systems and analogelectronic systems. However, the DDCzone sensor is different from theanalog electronic thermostat.
DDC controls provide much flexibilityand considerable diagnostic capability.DDC controllers can be connectedtogether to form a network ofcontrollers. Once the controllers arenetworked, they can be monitored forproper operation from a remotelocation. Commands and overrides canbe sent for groups of controllers at onetime to make system-wide changes.Commands and overrides can be sentto individual units to allow problemdiagnosis, temporary shutdown,startup schedules or other specializedchanges. When integrated into abuilding management system, theoperation of the VAV terminal unitsystem can be modified to do suchthings, as coincide with occupancyschedules and reduce energy charges.
DDC control of VAV terminal units is akey element in providing intelligentand responsive building management.Precision control, flexible comfort, andafter hours access are all available withthe VariTrane DDC control system forVAV terminal units.
Key features of the system include:
An advanced unit controller
Flexible system design
User-friendly interaction
Analog Electronic Controls BasicInformationAnalog electronic controls continue tobe useful in specific applications. Theusers of analog electronic controls canbenefit from the analog electronicproduct without the necessary aircompressor capacity for pneumaticapplications or computer-literatepersonnel for DDC applications.
However, as more and more peoplebecome computer literate, DDCcontrols have become the standard fornon-pneumatic VAV terminal unitcontrols. The analog electronic controlsystem will control room temperatureby modulating the position of theelectronic air valve in response to zonetemperature changes. VariTrane analogelectronic controls are only available inpressure-independent operation.Therefore, the flow is proportional tothe deviation from the zone setpoint.The primary airflow through the airvalve is monitored by means of anelectronic pressure transducerconnected to the standard VariTraneflow ring. The thermostat used withthe VariTrane electronic control systemis a thermistor which completes avoltage divider circuit when wired backto the analog control board. Thethermostat is designed to operatespecifically with VariTrane analogelectronic controls and is notinterchangeable with the VariTrane DDCzone sensor.
Pneumatic Controls Basic InformationPneumatic controls modulate airpressure of a controller to maintainsetpoint. For VAV systems, there aretwo primary types of pneumaticcontrollers—the room thermostat andthe pneumatic volume regulator (PVR).
Room ThermostatsThe most visible controller to thecustomer is the room thermostat.Pneumatic room thermostats can beclassified by two characteristics: thetubing connection(s) to the thermostatand the action of the thermostat outputin response to a change in the input.
Room thermostats are available inmodels that require a one-pipe or atwo-pipe configuration. The name isderived from the number of tubes thatmust run to the thermostat location.The difference is really in theconstruction of the thermostats. Thetwo-pipe thermostats have a constantpressure supply connected via an airtube to the thermostat supply air port.The supply air travels through thethermostat’s relays, levers, diaphragm,and bleed port to produce an output.The output line is connected to theoutput port of the thermostat andextends to the controlled device. The
one-pipe thermostat has, as its namesuggests, only one air line connection.The thermostat works by opening andclosing an air bleed valve. This willeither decrease or increase thepressure on the controlled device,which is connected to the same linethat runs to the thermostat.
Room thermostats also can beclassified by their reaction to a changein temperature. Room thermostatsclassified this way are denoted aseither direct-acting or reverse-acting.Direct-acting thermostats will increasetheir output pressure as thetemperature the thermostat measuresincreases.
On the contrary, reverse-actingthermostats will decrease their outputpressure as the temperature thethermostat measures increases.

ControlTypes
Pneumatic Volume RegulatorsThese controllers accept the roomthermostat signal and modulate theVAV terminal unit primary air damper.The primary air damper is controlledfor an airflow setpoint that isdetermined by the room thermostat.The thermostat increases the PVR’sairflow setting when the temperaturein the space is warm. On the otherhand, the thermostat decreases thePVR’s airflow setting when thetemperature in the space is cold.
Currently, VariTrane offers two modelsof pneumatic volume regulators in itscontrols offering—the 3011 regulator(used in most applications) and the3501 model (used in dual-ductconstant- volume applications). Theprimary difference is the 3501 PVR’sability to change the velocity pressurelinearly with a change in thermostatpressure, which results in improvedstability at low flows. In contrast, the3011 PVR resets the velocity pressurewith a change in thermostat pressure.
Reset Control of Minimum andMaximum Flow—The 3011 PVR and3501 use fixed reset control ofminimum and maximum flow settings.The primary benefit of fixed reset in apneumatic volume regulator is stableflow control without excessive dampermovement.
Fixed Reset—A fixed reset controlleroperates over a thermostat signalchange of 5 psi between minimum andmaximum flow, regardless of thedifferential pressure flow sensor signal.The thermostat is usually set for a gainof 2.5; i.e. it produces a 2.5 psi output
change per degree of spacetemperature change. This controlstrategy provides stable flow controlwith the primary air valve throttlingbetween minimum and maximumflow over a 2°F space temperaturechange.
Example 1: Air valve with a 6" inlet,Pneumatic thermostat gain = 2.5 psi/degree:
Minimum Flow = 0 cfm, 0.0 in. wgflow signal
Maximum Flow = 680 cfm, 2.0 in. wgflow signal
2.0 in. wg signal range
The damper will modulate from zero tomaximum position over a 2°Ftemperature change.
Bleed Port to Atmosphere—Bleeding air to the atmosphere is anormal operation for a volumeregulator. The 3011 volume regulatoraddresses this function with adedicated bleed port. When air is bledthrough the flow sensor, the differentialpressure signal from the sensor isaffected. As a result, the flow sensorsignal can be radically altered if thevolume regulator is bleeding air, andmay cause excessive dampermovement.
Calibration—The minimum andmaximum settings are independent ofeach other and need to be set onlyonce during calibration.
Signal Configuration Flexibility—Both can be configured to work withboth normally-open and normally-closed pneumatic air valves, and bothdirect-acting and reverse-actingthermostats.

FlowMeasurementand Control
Flow Measurement andControlOne of the most importantcharacteristics of a VAV terminal unit isits ability to accurately sense andcontrol airflow. The VariTrane terminalunit was developed with exactly thatgoal in mind. The patented, multiple-point, averaging flow ring measuresthe velocity of the air at the unitprimary air inlet. The differentialpressure signal output of the flow ringprovides the terminal unit controller ameasurement of the primary airflowthrough the inlet. The terminal unitcontroller then opens or closes theinlet damper to maintain the controllerairflow setpoint
perpendicular to the airflow. The low-pressure taps on the VariTrane flowring measure a pressure that is parallelto the direction of flow but in theopposite direction of the flow. This“wake pressure” that the downstreamring measures is lower than the actualduct static pressure. The differencebetween the “wake pressure” and thestatic pressure can be accounted for sothat the above relationship betweenflow and differential pressure remainvalid. The difference also helps create alarger pressure differential than thevelocity pressure. Since the pressuresbeing measured in VAV terminal boxapplications are small, this largerdifferential allows transducers andcontrollers to measure and control atlower flow settings than wouldotherwise be possible.
The average velocity of air travelingthrough the inlet is expressed inthe equation:
Where:FPM = Velocity of air in feet per
minute1096.5 = A constantVP = The velocity pressure of the
air expressed in inches ofwater
DENS = The density of the airexpressed in pounds percubic foot
Often, the density is assumed to be aconstant for dry air at standardconditions (68°F (20°C)) and sea levelpressure of 14.7 psi (101.4 kPa)). Theseconditions yield the followingcommonly used equation:
The velocity pressure is defined as thedifference between the total pressurein the duct and the static pressure inthe duct:
VP = TP - SP (All units are expressed ininches of water)
The amount of air traveling throughthe inlet is related to the area of theinlet and the velocity of the air:
AIRFLOW = AREA (square feet) xAVERAGE VELOCITY (feet per minute)
AccuracyThe multiple, evenly spaced orifices inthe flow ring of the VariTrane terminalunit provide quality measurementaccuracy even if ductwork turns orvariations are present before the unitinlet. For the most accurate readings,there should be a minimum of 1½diameters, and preferably 3 diameters,of straight-run ductwork before theinlet connection. The straight-runductwork should be of the samediameter as the air valve inletconnection. If these recommendationsare followed, and the air density effectsmentioned below are addressed, theflow ring should measure primaryairflow within ±5% of unit nominalairflow.
Air Density EffectsChanges in air density due to theconditions listed below sometimescreate situations where the standardflow sensing calibration parametersmust be modified. These factors mustbe accounted for to achieve accuracywith the flow sensing ring. Designers,installers, and air balancers should beaware of these factors and know of thenecessary adjustments to correct forthem.
Air Pressure Measurement Orientations
Flow MeasurementMost VAV terminal units contain adifferential pressure airflowmeasurement device, mounted at theprimary air inlet, to provide a signal tothe terminal unit controller. Numerousnames exist for the differentialpressure measurement device—flowsensor, flow bar, flow ring. Thedifferential pressure measured at theinlet varies according to the volumetricflow rate of primary air enteringthe inlet.
The total pressure and the staticpressure are measurable quantities.The flow measurement device in a VAVterminal unit is designed to measurevelocity pressure. Most flow sensorsconsist of a hollow piece of tubing withorifices in it. The VariTrane air valvecontains a flow ring as its flowmeasuring device. The flow ring is tworound coils of tubing. Evenly spacedorifices in the upstream coil are thehigh-pressure taps that average thetotal pressure of air flowing throughthe air valve. The orifices in thedownstream ring are low-pressure tapsthat average the air pressure in thewake of flow around the tube. Bydefinition, the measurement of staticpressure is to occur at a point

FlowMeasurementand Control
Elevation—At high elevations the air isless dense. Therefore, when measuringthe same differential pressure atelevation versus sea level the actualflow will be greater at elevation than itwould be at sea level. To calculate thedensity at an elevation other thanstandard conditions (mostmanufacturers choose sea level as thepoint for their standard conditions),you must set up a ratio between thedensity and differential pressure atstandard conditions and the densityand differential pressure at thenew elevation.
Since the data from the manufactureris published at standard conditions,this equation should be solved for thedifferential pressure at standardconditions and the other quantitiessubstituted to determine the ratio forthe differential pressure measured atthe new conditions.

Duct Pressure and Air TemperatureVariations—While changes in thesefactors certainly affect the density ofair, most operating parameters whichVAV systems need keep these effectsvery small. The impact on accuracy dueto these changes is less than one halfof one percent except in very extremeconditions (extreme conditions aredefined as those systems with staticpressures greater than 5 in. wg(1245 Pa) and primary air temperaturesgreater than 100°F (37.8°C)). Sincethose types of systems occur soinfrequently, we assume the effects ofduct pressure and air temperaturevariations to be negligible.
Linearity —With the increase in DDCcontrols over pneumatic controls, theissue of linearity is not as great as itonce was. The important aspect of flowmeasurement versus valve position isthe accuracy of the controller indetermining and controlling the flow.Our units are tested for linearity andthat position versus airflow curve isdownloaded and commissioned in thefactory to insure proper control ofthe unit.

Hot Water Reheat
Hot water heating coils are generallyapplied on VAV terminal units as reheatdevices. When applying these coils it isimportant to make sure that they areoperating in the proper air flow andwater flow range. Either a two-way or athree-way valve controls the coils.
The flow and differential pressure aregenerally the known quantities. Theequation is solved for the flowcoefficient. The flow coefficient is thencompared to the published CV valuesfor the control valves that are available.The control valve with the CV that is theclosest, but greater than, the calculatedflow coefficient is the correct choice forthe control valve. This choice will keepthe valve pressure drop below themaximum allowable valve pressuredrop. The valve pressure drop shouldthen be checked against the coilpressure drop. If the coil pressure dropis appreciably larger than the valvepressure drop, a valve with a smallerCV should be selected to produce alarger control valve pressure drop. Ifthis new valve has a pressure drop thatis much larger than the maximumallowable pressure drop for valves, thesystem designer should be consultedto make sure that the system hot waterpumps can deliver the water at thenew conditions.
Electric ReheatElectric heating coils are applied onVAV terminal units as terminal reheatdevices. Electric heat coil capacity israted in kilowatts (kW). Coils areavailable with the total capacity dividedinto one, two, or three stages.
Electric heat coils are available insingle-phase or three-phase models.This refers to the type of power sourceconnected to the coil. Single-phasemodels have resistance elementsinternally connected in parallel. Three-phase models have resistanceelements internally connected in adelta or a wye configuration.
The current draw for the electric coilwill depend upon whether it is a single-phase coil or a three-phase coil. Thecurrent draw is necessary fordetermining what size wire should beused to power the electric coils andhow big the primary power fusingshould be.

ReheatOptions
The most important factor when sizingvalves is the coefficient of velocity orCV. The CV is defined as the flow rate, ingallons of 60°F (15.56°C) water, that willpass through the valve in one minutewith a one pound pressure drop. Thecoefficient of velocity, which iscommonly called the flow coefficient,is an industry standard rating. Valveshaving the same flow coefficient rating,regardless of manufacturer, will havethe same waterside performancecharacteristics.
The equation that governs valvesizing is:

∆ P = The maximum allowabledifferential pressure acrossthe valve in psi

temperature across the coil(usually 50°F (10°C))
Electric heat coils are available withmagnetic or mercury contactors.Magnetic contactors are lessexpensive than mercury contactors.However, mercury contactors can becycled at a more rapid rate withoutfailing. Mercury contactors are ratedfor heavier duty and should be used inas many applications as possible. Forpneumatic applications the electriccoils are available with factory-installedpressure-electric switches.
The equations for current draw forthese coils are:
kW x 1000
1 φ amps = Primary Voltage
kW x 1000
3 φ amps = Primary Voltage x √ 3
VariTrane three-phase electric heat isavailable in balanced configurations.For example, a 9 kW three-phase coil,each stage would carry 1/3 or 3 kW ofthe load.
It is important to note that these coilshave certain minimum airflow rates foreach amount of kW heat the coil cansupply to operate safely. These airflowvalues are based upon a maximumrise across the electric heat coil of50°F (10°C).

Insulation
InsulationInsulation in a VAV terminal unit is usedto avoid condensation on the outsideof the unit, to reduce the heat transferfrom the cold primary air entering theunit, and to reduce the unit noise. TheVariTrane line offers four types ofinsulation for units. The type of facingclassifies the types of insulation. Toenhance IAQ effectiveness, edges of allinsulation types have metalencapsulated edges.
Matte-FacedThis type of insulation is used fortypical applications. It consists of afiberglass core covered by a high-density skin. The dual-densityconstruction provides good soundattenuation and thermal performance.
Foil-FacedThis type of insulation is used inapplications where there is someconcern regarding airbornecontaminants entering the space, ordirt being trapped in the fibers of theinsulation. The insulation is composedof a fiberglass core laminated to a foilsheet. Foil-faced insulation will providethe same sound attenuationperformance as matte-faced insulation.

Double-WallThis type of insulation is used inapplications where there is extremeconcern regarding airbornecontaminants entering the space or dirtbeing trapped in the fibers of theinsulation. The insulation is the sameas the matte-faced insulation.However, after the insulation isinstalled, a second solid wall of26-gage steel covers the insulation. Allwire penetrations of this insulation arecovered by a grommet. This type ofinsulation will result in higherdischarge and radiated sound power.
Closed-CellThis type of insulation is used inapplications where IAQ and fibers areof primary concern. The acoustics ofthe closed-cell insulation are similar todouble-wall insulation. The thermalproperties are similar to fiberglassinsulation. This insulation containsno fiberglass.

Acoustics
Acoustical Best Practices
Sizing of unitsIncreasing the size of a unit can helpdecrease its sound characteristics.Increasing the size of a fan in a fan-powered unit can also help improvesound levels.
When increasing sizes, ensure the unitshave accurate flow measurement atminimums and the fan will operateproperly at the lower speed.
Series vs. Parallel Fan-Powered UnitsAcoustical considerations affectwhether a series or parallel fan-powered terminal unit is selected. Bothunits have their advantages.
The parallel unit has the advantage ofthe fan being on and contributing tothe sound levels only when heating isneeded. The fans are usually smallerbecause they are sized for 30–60% oftotal unit flow. This creates a unit whichis quieter than series units. Thedisadvantage of the parallel unit is thatthe sound is intermittent.
The primary acoustic benefit to theseries fan-powered unit over a parallelfan-powered unit is that the fan runscontinuously. Sometimes the unit canbe selected at slightly higher soundlevels due to the constant nature of thesound.
The primary acoustic disadvantage theseries unit has compared to the parallelunit is the need to size the unit fan forthe total room airflow. Series unitsrequire a larger, louder fan thanparallel configurations.
Note: Operating parallel units with acontinuously operating fan may beconsidered for some applications. Thisprovides the quietest overall fan-powered system with the benefit ofcontinuous fan operation.
Insulation typesInsulation is a factor to consider whendealing with the acoustics of theterminal units. Most insulation typeswill provide similar acoustical results,but there are exceptions. Double-walland closed-cell foam insulation willgenerally increase your sound levelsbecause of the increased reflectivesurface area that the solid inner-walland closed-cell construction provides.This increase in sound will have to bebalanced with the IAQ and cleanabilityconsiderations of the dual-wall andclosed-cell construction.
Placement of unitsWhere the units are placed in abuilding can have a significant impacton the acceptable sound levels.Placement of units above non-criticalspaces (hallways, closets, andstorerooms) will help to reduceconcerns about radiated sound fromthe unit.
Unit AttenuationTerminal unit-installed attenuators arean option available to provide pathsound attenuation. Manufacturer-provided attenuators on the dischargeof a terminal unit are targeted atreducing discharge path noise and aretypically a simple lined piece ofductwork. It would often be easier andless expensive to design thedownstream ductwork to be slightlylonger and require the installingcontractor to include lining in it.Attenuators on the plenum inlet of fan-powered terminals are targeted atreducing radiated path noise since theplenum opening on a fan-poweredterminal unit is typically the criticalpath sound source. Significantreduction in radiated path noise canresult from a well-designed inletattenuator. The attenuation from theseattenuators is due to simple absorptionfrom the attenuator lining andoccupant line of sight sound pathobstruction. Therefore, longerattenuators and attenuators thatrequire the sound to turn multiplecorners before reaching the occupiedspace get superior results, particularlyin the lower frequency bands.
Raw unit sound data can be goodmeasurement criteria for evaluation. Inusing this as a basis for comparison,the designer needs to make sure thatthe information is based on the ARIStandard 880 that gives the procedurefor testing.
Specifying NC or RC sound levels is apossible comparison, but the designerneeds to be sure the comparison is fair.Two options are to specify theattenuation effect on which you wouldlike the units to be evaluated or tospecify that ARI Standard 885-98transfer functions be used. Theimportance of ARI Standard 885-98 isthat it is the first ARI Standard thatspecifies exact transfer functions to beused for evaluation. Previous versionsof the standard gave guidelines, butthe manufacturers could choose theirown set of factors.
Attenuators that are simple “cups” atthe plenum inlet(s) have been shownin Trane’s acoustical mock-up to provideno measurable reduction in soundpressure in the critical octave bandswhich set the occupied spacenoise criteria.
Certification and TestingTerminal units should be submittedbased on the same criteria. There areseveral ways to ensure this bycertification and testing.
By using NC sound levels, it is possibleto express acceptable sound levels forvarious types of buildings orenvironments. A few examples are:
Concert Hall NC-22Hospital Room NC-30School Room NC-35General Office NC-40Cafeteria NC-45Factory NC-65
Path AttenuationThe sound that is generated by aterminal unit can reach the occupiedspace along several paths. The terminalunit generated sound will loseenergy—i.e., the energy is absorbed by

Acoustics
path obstacles) as it travels along thepaths to the occupied space. Thistendency to dissipate energy as ittravels to the occupied space is calledpath attenuation. The amount ofenergy lost along a particular path canbe quantified and predicted using theprocedure outlined in ARI-885. Eachpath must be considered whendetermining acceptable sound powergenerated by a terminal unit.
The term “transfer function” is oftenused to describe the entire pathattenuation value for each octave band(i.e., the sum of all components of aparticular path).
Examples of path attenuation includelocating the terminal unit away fromthe occupied space, increasing the STC(sound transmission classification) ofthe ceiling tile used, internally liningductwork, drywall lagging the ceilingtiles or enclosing the terminal unit indrywall. All of these choices have costsassociated with them that must beweighed against the benefits. Some ofthese alternatives can be acousticallyevaluated from application dataprovided in ARI-885. Others mayrequire professional analysis from anacoustical consultant.
Computer ModelingComputer modeling of acousticalpaths is available to help estimatesound levels and determine problemsources. The software used by Trane forcomputer modeling is called TraneAcoustics Program ( TAP™).
TAP can analyze different roomconfigurations and materials to quicklydetermine the estimated total soundlevels (radiated and discharged) in aspace.
The Trane Official Product SelectionSystem (TOPSS™) can also be used todetermine sound levels of terminalunits. You can base selections on amaximum sound level and enter yourown attenuation factors (defaultsbased on ARI-885 are also available).

Duct Design
Duct DesignDesigning cost-effective VAV ductsystems is challenging. Some ductdesign methods result in betterpressure balance than others do. Ductshape and duct material can influenceduct system design and cost. Inaddition, duct layout is properlydesigned for optimal duct installationand operation.
Design MethodsThe two most widely used supply ductdesign methods—equal friction andstatic regain—are discussed below.
Equal Friction – Using this method,ducts are sized at design flow to haveroughly the same static pressure dropfor every 100 feet of duct. Staticpressures throughout the duct systemcan be balanced at design flow usingbalancing dampers, but are no longerbalanced at part load flows. For thisreason, equal friction duct designs arebetter suited for constant volumesystems than for VAV systems. If theequal friction method is used for theVAV supply duct design, the terminalunits usually require pressure-independent (PI) control capability toavoid excessive flow rates when ductpressures are high.
In VAV systems, the ducts locateddownstream of the terminal unit areusually sized for equal friction. Theadvantage of this design method is itssimplicity. Often, calculations can bemade using simple tables and ductcalculators. Drawbacks includeincreased higher total pressure dropsand higher operating costs.
Static Regain – In the static regainmethod, ducts are sized to maintainconstant static pressure in eachsection, which is achieved by balancingthe total and velocity pressure drops ofeach section. In other words, staticpressure is “regained” by the loss ofvelocity pressure. Since the staticpressures throughout the duct systemare roughly balanced at design andpart load flow, static regain ductdesigns can be used successfully foreither constant volume or VAVsystems. When the static regainmethod is used for VAV systems, thesystem is roughly pressure balancedat design.
Advantages of the static regain methodinclude reduced total pressure drops,lower operating costs, and balancedpressures over a wide range of flows.The drawback of this design is thetime-consuming, iterative calculationprocedure and for large systems, it isessential to have a duct designcomputer program.
Duct Design ProgramThe Trane Company has developed acomputer program, VariTrane™ DuctDesigner, to aid in the duct designprocess. This program is used to
calculate duct sizes, fitting sizes,terminal unit sizes, and pressure dropsaccording to the equal friction or staticregain method.
The duct design program can be easilyincorporated into the selection of VAVterminal units. The inputs and outputsfor the program enable VariTrane unitsto be selected based on the conditionsyou require. This makes selecting andscheduling units much easier. Contactthe local sales office or the TraneC.D.S.™ department for more detailson this program.

SelectionProgram
Selection ProgramThe advent of personal computers hasserved to automate many processesthat were previously repetitive andtime-consuming. One of those tasks isthe proper scheduling, sizing, andselection of VAV terminal units. Tranehas developed a computer program toperform these tasks. The software iscalled the Trane Official ProductSelection System (TOPSS™).
The TOPSS program will take the inputspecifications and output the properlysized VariTrane VAV terminal unit alongwith the specific performance for thatsize unit.
With TOPSS, the user can integrateselections of single-duct, dual-duct,and fan-powered VAV boxes with otherTrane products allowing you to selectall your Trane equipment with onesoftware program.
The program has several requiredfields, denoted by red shading in theTOPSS screen, and many otheroptional fields to meet the givencriteria. Required values for selectionsinclude the maximum and minimumairflows, the control type, and unitmodel. When selecting models withreheat, information regarding theheating coil is needed for selection. Inaddition, the user is given the option tolook at all the information for oneselection on one screen or as aschedule with the other VAV units onthe job.
Also, TOPSS will calculate sound-power data for a selected terminal unit.The user can enter a maximumindividual sound level for each octaveband or a maximum NC value. Theprogram will calculate acoustical datasubject to default or user suppliedsound attenuation data.
The program has many time-savingfeatures such as:
Copy/Paste from spreadsheets likeMicrosoft® Excel
Easily arranged fields to match yourschedule
Time-saving templates to store defaultsettings
Several output report options includingschedules
The user can also export the ScheduleView to Excel to modify and put into aCAD drawing as a schedule.

BestPractices
Common MistakesSome of the most common system orinstallation errors are discussed below.
Reducers at Unit InletThis problem is a very common issuethat is seen in applications of VariTraneproducts. It is often mistaken by thosein the field as an unacceptably largestatic pressure drop through the unit. Itis also sometimes mistaken as amalfunctioning flow ring, pressuretransducer (if DDC or analog electroniccontrols are present) or PVR (ifpneumatic controls are present).
This problem is sometimesunknowingly encountered because ofthe capability of the VariTrane unit toallow greater airflow for a specific sizeduct than other terminal units. Forexample, a project engineer specifiesan 8" (203 mm) round take off from themain duct trunk to the VAV terminalunit. The person supplying the VAVterminal unit checks the requiredairflow and finds that a VariTrane unitwith a 6" (152 mm) inlet will providethe specified terminal unitperformance. The terminal unitsupplier submits, receives approval,and orders the 6" (152 mm) inlet unit.While this is happening, the installingcontractor has run the connecting ductfrom the main trunk to the terminalunit in the specified 8" (152 mm) round.The unit arrives at the job site, and theinstaller notices that the 8" (203 mm)duct and the 6" (152 mm) terminal unitinlet do not match. To get the unitinstalled, an 8- to 6-inch reducer isplaced at the inlet to the terminal unitair valve.
The reducer will cause a phenomenoncalled flow separation at the unit inlet.Fluid dynamics analysis can present adetailed technical explanation of flowseparation, but the characteristicsimportant to this discussion are theproduction of pressure loss andturbulence. The reducer will have asignificant static pressure dropassociated with it since the air velocityis increased (i.e., static pressure isgiven up for increased velocitypressure). The pressure loss issometimes mistaken as a loss due tothe function of the terminal unit. Theturbulence is at its greatest justdownstream of the reducer.Unfortunately, this is the location of theflow ring at the air-valve inlet. Thereducer will cause the flow ring to givean inaccurate and inconsistent readingbecause of the turbulent air.
The solutions to this situation are:
Locate the reducer upstream of theterminal unit at least three ductdiameters to eliminate flow separationand turbulence at the unit inlet and toimprove the airflow measurementaccuracy.
Consider proper sizing of the terminalunit in the duct design and account forthe pressure loss of the reducer in thecentral fan selection if a reducer isrequired. Be cautious of “oversizing” aVAV terminal. It is good practice tomake sure that the inlet duct velocity atthe minimum airflow setting is nolower than 500 feet per minute.
Improper Use of Flexible DuctworkWhile flexible ductwork has manybenefits, improper use can causenumerous problems in a VAV system.Flexible ductwork causes turbulentairflow and relatively large static
pressure drops. Flexible ductwork at aprimary damper inlet (i.e., the flowsensor location) may cause flowaccuracy and repeatability problemsdue to turbulence. The use of flexibleductwork should be primarily limited tothe downstream side of the terminalunits in a VAV system. Use of flexibleductwork upstream of terminal unitsshould be kept to an absoluteminimum. All runs of flexible ductworkshould be kept as short as possible.While most know these guidelines, theease of installation which flexibleductwork provides is always anenticement to push the limits of whatare acceptable practices.
Static Pressure Measurement ErrorsImproper measurement techniques forstatic pressure can lead many tomistakenly believe that the terminalunit is causing a large pressure drop inthe system. The chief error made hereis taking a static pressuremeasurement in turbulent locationssuch as flexible ductwork or neartransitions. This produces invalid staticpressure readings. Another errorcommonly made is trying to read thestatic pressure at the same point as theflow sensing device. The inlets to VAVterminal units produce turbulence andwill give poor readings. Flow sensorswith their multiple-point averagingcapability are best equipped to dealwith this type of flow, while a single-point static probe is not. Anothercommon error is the incorrectorientation of the static pressure probe.The static pressure is correctlymeasured when the probe is orientedperpendicular to the direction ofairflow. The probe, or a part of it,should never be facing the direction ofairflow, because the total pressure willinfluence the reading of the probe.

SelectionProcedure
This section describes the catalogselection of single-duct VAV terminalunits with specific examples. Acomputer selection program is alsoavailable to aid in selection of VAVterminal units.
Selection of single-duct VAV terminalunits can involve three elements:
Air valve selectionHeating coil selection (if required)Acoustics
Air Valve Selection
The wide-open static pressure andairflows are found in the performancedata section of the catalog. To select anair valve, locate the required designcooling airflow for your terminal unittype and find the smallest air valve sizethat has a pressure drop equal to orlower than the maximum wide-openstatic pressure requirement.
Selection Example—Cooling Only VCCF Terminal Unit
Design cooling airflow: 1700 cfmMaximum wide openAir pressure drop: 0.25 in. wgMinimum cooling airflow: 850 cfm
From the performance data charts,select a valve size 12, which has a wide-open static pressure drop of 0.01 in. wg
Check the minimum and maximum cfmdesired with the minimum andmaximum cfm allowed in the table inthe general data section. The maximumsetting of 1700 cfm is within theacceptable range. The desired minimumsetting of 850 cfm is acceptable for thecooling only box desired. Note that if anelectric reheat box was selected, theminimum cfm would be dependentupon the kW of the electric heater. (SeeElectric Heat Unit Selection.)
Heating Coil Selection (Ifrequired)First, determine the amount of heatrequired to meet space anddownstream duct heat losses from aload calculation.
Hot Water HeatSelect a hot water coil sufficient to meetthe design heat loss.
Example:VCWF, Hot Water Unit Heat, Size 12(See air Valve Selection)Heating airflow: 850 cfmHot water flow: 1.0 gpmDesign Heat Loss: Q =25 MBh
Select hot water coil from the coilperformance table in the PerformanceData section of the catalog.
Selection:A one-row coil is sufficient to meetdesign conditions. From the Hot WaterCoil Capacity Data of the PerformanceData Section, a one-row coil for a size12 air valve will operate at the aboveconditions as follows:
Coil Capacity: 25.17 MBhWater pressure drop: 0.72 ft WPD
Air pressure drop (APD) of the hotwater coil is included in the chartpreceding the hot water coilperformance data section.
APD = 0.35 in. wg
Electric HeatDetermine the kW required to meetzone design heat loss.
kW = MBh / 3.414
MBh = Design Heat Loss
Select the nearest available kW withvoltage and steps desired from theelectric heater kW guideline table in thePerformance Data section of thecatalog.
Example:VCEF, Electric Unit Heat, Size 12(See Air Valve Selection)Heating airflow: 850 cfmVoltage: 277/60/1 VACDesign Heat Loss: Q = 25 MBh
kW = Q/3.414
kW = 25/3.414
kW = 7.3
Selection:Select 7.5 kW from the electric heattable in the voltage and stagesrequired. The table shows theminimum cfm allowable for the kWselected. The static pressurerequirement is shown as 0.06 in. wgfor this example with a design coolingflow of 1700 cfm.
Check Leaving Air Temperature:
T is the primary entering airtemperature 55°F for this example.
Decide if leaving air temperature of82.8°F is satisfactory for yourapplication.
AcousticsThe acoustical data found in the"Performance Data" section of the VAVcatalog is used to make adetermination of the amount of noisethe terminal unit will generate. Locatethe table for the VAV terminal unit ofinterest. Sound power data and anequivalent NC level for an ARI 885-98transfer function is listed.
Example:VCCF, Cooling-Only Terminal Unit, Size10 (See air Valve Selection)Cooling Airflow: 1100 cfm
Maximum inlet staticpressure: 1.5 in. wg
Interpolation gives sound powerdata of:
called the Trane Official ProductSelection System (TOPSS).
The TOPSS program will take the inputspecifications and output the properlysized VariTrane VAV terminal unit alongwith the specific performance for thatsize unit.
The program has several requiredfields, denoted by red shading in theTOPSS screen, and many otheroptional fields to meet the criteria youhave. Required values includemaximum and minimum airflows,control type, and model. If selectingmodels with reheat, you will be
LAT = 3414 x 7.51.085 x 850
+ 55 = 82.8
LAT = Q1.085 x CFM
+ T
The maximum NC level is NC-37. If themaximum NC level was exceeded, itwould have been necessary to reselectthe next larger unit size.
Computer SelectionThe advent of personal computers hasserved to automate many processesthat were previously repetitive andtime-consuming. One of those tasks isthe proper scheduling, sizing, andselection of VAV terminal units. Tranehas developed a computer program toperform these tasks. The software is
The NC level above is determined byusing either the catalog’s ARI 885-98(mineral fiber for radiated sound)transfer function for the conditionsshown in the acoustics table. Adifferent transfer function could beapplied as conditions dictate.

The user can select single-duct, dual-duct, and fan-powered VAV boxes withthe program, as well as most otherTrane products, allowing you to selectall your Trane equipment with onesoftware program.
The program will also calculate soundpower data for the selected terminalunit. The user can enter a maximumindividual sound level for each octaveband or a maximum NC value. Theprogram will calculate acoustical datasubject to default or user suppliedsound attenuation data.
Schedule ViewThe program has many time-saving features such as:Copy/Paste from spreadsheets like Microsoft® ExcelEasily arranged fields to match your scheduleTime-saving templates to store default settings
The user can also export the Schedule View to Excel to modify and put into a CADdrawing as a schedule.

Minimum Circuit Ampacity (MCA) EquationMCA = heater amps x 1.25
Maximum Overcurrent Protection (MOP) EquationMOP = heater ampsHowever since MOP ≤ MCA, then choose next fuse greater than MCA.Units without electric reheat would use smallest fuse sizing.Standard Fuse Sizes: 15, 20, 25, 30, 35, 40, 45, 50, and 60.
Example–For MOP of Single-Duct UnitA model VCEF, electric reheat unit size 14 has 480/3 phase 15 kW electric reheat with 2 stages.15 kW – 480/3 heater 15 x 1000 = 18.06
480 x 1.73MCA = 18.06 x 1.25 = 22.58 amps. Since MOP ≤ MCA, then MOP = 25.
Example–For total current draw of unitA model VCEF, electric reheat unit size 14 has 480/3 phase 15 kW electric reheat with 2 stages.Electric Actuator = 0.17DDC UCM Control Board = 0.3315 kW – 480/3 heater 15 x 1000 = 18.06

UNIT CONTROLS SEQUENCE OFOPERATIONThe unit controller continuouslymonitors the zone temperature againstits setpoint and varies the primaryairflow as required to meet zonesetpoints. Airflow is limited by
minimum and maximum positionsetpoints. Upon a further call for heatafter the air valve is at minimum, anyhot water or electric heat associatedwith the unit is enabled.
DIRECT DIGITAL CONTROLS
DDC Actuator—Trane 3-wire,24-VAC, floating-point control actuatorwith linkage release button. Torque is35 in-lb minimum and is non-springreturn with a 90-second drive time.Travel is terminated by end stops atfully-opened and -closed positions. Anintegral magnetic clutch eliminatesmotor stall.Direct Digital Controller—Themicroprocessor based terminal unitcontroller provides accurate, pressure-independent control through the useof a proportional integral controlalgorithm and direct digital controltechnology. The controller, named theUnit Control Module (UCM), monitorszone temperature setpoints, zonetemperature and its rate of change,and valve airflow using a differentialpressure signal from the pressuretransducer. Additionally, the controllercan monitor either supply duct airtemperature or CO2 concentration viaappropriate sensors. The controller isprovided in an enclosure with 7/8"(22 mm) knockouts for remote controlwiring. A Trane DDC zone sensoris required.DDC Zone Sensor—The UCMcontroller senses zone temperaturethrough a sensing element located inthe zone sensor. In addition to thesensing element, zone sensor optionsmay include an externally-adjustablesetpoint, communications jack for usewith a portable edit device, and anoverride button to change theindividual controller from unoccupiedto occupied mode. The override buttonhas a cancel feature that will return thesystem to unoccupied. Wired zonesensors utilize a thermistor to vary thevoltage output in response to changesin the zone temperature. Wiring to theUCM controller must be 18- to 22-awg.twisted pair wiring. The setpointadjustment range is 50–88ºF (10–31°C).Depending upon the features availablein the model of sensor selected, thezone sensor may require from a 2-wireto a 5-wire connection. Wireless zonesensors report the same zoneinformation as wired zone sensors, butdo so using radio transmittertechnology. Therefore with wireless,wiring from the zone sensor to theUCM is unnecessary.
Digital Display Zone Sensor withLiquid Crystal Display (LCD)—The digital display zone sensor containsa sensing element, which sends a signalto the UCM. A Liquid Crystal Display(LCD) displays setpoint or spacetemperature. Sensor buttons allow theuser to adjust setpoints, and allow spacetemperature readings to be turned on oroff. The digital display zone sensor alsoincludes a communication jack for usewith a portable edit device, and anoverride button to change the UCM fromunoccupied to occupied. The overridebutton has a cancel feature, whichreturns the system to unoccupied mode.System Communications— TheController is designed to send andreceive data from a Tracer Summit™
or other Trane controllers. Current unitstatus conditions and setpoints may bemonitored and/or edited via this datacommunication feature. The networktype is a twisted wire pair shieldedserial communication.
ANALOG ELECTRONIC CONTROLS
Analog Actuator—A Trane 3- wire,24-VAC, floating-point control actuatorwith linkage release button. Torque is35 in-lb minimum and is non-springreturn with a 90-second drive time.Travel is terminated by end stops atfully-opened and -closed positions. Anintegral magnetic clutch eliminatesmotor stall.Analog Electronic Controller—Thecontroller consists of a circuit board thatoffers basic VAV unit operation andadditional override functions andoperates using 24 VAC power. Thecontroller uses a capacitive typepressure transducer to maintainconsistent air delivery regardless ofsystem pressure changes. The enclosurehas 7/8" (22 mm) knockouts for remotecontrol wiring. A Trane electronic zonesensor is required.Analog Electronic Thermostat—Thissingle-temperature, wall-mountedelectronic device utilizes a thermistor tovary the voltage output in response tochanges in the zone temperature.Connections to the VAV unit circuitboard are made using standard three-conductor thermostat wire. The setpointadjustment range is 63–85ºF (17–29°C).The sensor is available in two models.One model has a concealed, internally-adjustable setpoint. The other modelhas an externally-adjustable setpoint.

SelectionProcedure
This section describes the catalogselection of dual-duct VAV terminal unitswith specific examples. A computerselection program is also available toaid in selection of VAV terminal units.
Selection of dual-duct VAV terminalunits can involve two elements:
Air valve selectionAcoustics
Air Valve Selection
The wide-open static pressure andairflows are found in the performancedata section of the catalog. To select theair valves, locate the required designcooling and heating airflows for yourterminal unit type and find their verticalintersection, with the smallest air valvesize that has a pressure drop equal to orlower than the maximum wide-openstatic pressure requirement.
Example:VDDF Terminal UnitDesign cooling airflow: 1000 cfmMaximum wide-openAir pressure drop: 0.25 in. wgMinimum cooling airflow: 500 cfmDesign heating airflow: 1000 cfmMaximum wide-openAir pressure drop: 0.25 in. wgMinimum heating airflow: 400 cfm
From the performance data charts,select a valve size 10 for cooling, whichhas a wide-open static pressure drop of0.09 in. wg. Select a size 10 for heating,which has a wide-open static pressuredrop of 0.09 in. wg.
Check the minimum and maximum cfmdesired with the minimum andmaximum cfm allowed in the table inthe general data section. The maximumsetting of 1000 cfm is within theacceptable range. The desired minimumsetting of 500 cfm is acceptable for theunit desired.
AcousticsThe acoustical data found in the"Performance Data" section of the VAVcatalog is used to make adetermination of the amount of noisethe terminal unit will generate. Locatethe table for the VAV terminal unit ofinterest. Sound power data and anequivalent NC level for an ARI 885-98transfer function is listed.
Example:VDDF, Cooling-Only Terminal Unit, Size10 cooling, Size 10 heating (See airValve Selection)Cooling Airflow: 1000 cfm
Maximum inlet staticpressure: 1.5 in. wg
Heating Airflow: 1000 cfm
Maximum inlet staticpressure: 1.5 in. wg
Interpolation gives sound power dataof:
Computer SelectionThe advent of personal computers hasserved to automate many processesthat were previously repetitive andtime-consuming. One of those tasks isthe proper scheduling, sizing, andselection of VAV terminal units. Tranehas developed a computer program toperform these tasks. The software iscalled the Trane Official ProductSelection System (TOPSS).
The TOPSS program will take the user’sinput specifications and output theproperly sized VariTrane VAV terminalunit along with the specificperformance for that size unit.
The program has several requiredfields, denoted by red shading in theTOPSS program, and many otheroptional fields to meet the criteria youhave. Required values includemaximum and minimum airflows,control type, and model. If selectingmodels with reheat, you will berequired to enter information to makethat selection also. The user is giventhe option to look at all the informationfor one selection on one screen or as aschedule with the other VAV units onthe job.
The user can select single-duct, dual-duct, and fan-powered VAV boxes withthe program, as well as most otherTrane products, allowing you to selectall your Trane equipment with onesoftware program.
The program will also calculate soundpower data for the selected terminalunit. The user can enter a maximumindividual sound level for each octaveband or a maximum NC value. Theprogram will calculate acoustical datasubject to default or user suppliedsound attenuation data.
The maximum NC level is NC-40. If themaximum NC level was exceeded, itwould have been necessary to reselectthe next larger unit size.
The NC level above is determined byusing either the catalog’s ARI 885-98(mineral fiber for radiated sound)transfer function for the conditionsshown in the acoustics table. Adifferent transfer function could beapplied as conditions dictate.

DDC Zone Sensor—The UCMcontroller senses zone temperaturethrough a sensing element located inthe zone sensor. In addition to thesensing element, zone sensor optionsmay include an externally-adjustablesetpoint, communications jack for usewith a portable edit device, and anoverride button to change the individualcontroller from unoccupied to occupiedmode. The override button has a cancelfeature that will return the system tounoccupied. Wired zone sensors utilize athermistor to vary the voltage output inresponse to changes in the zonetemperature. Wiring to the UCMcontroller must be 18 to 22 awg. twistedpair wiring. The setpoint adjustmentrange is 50–88ºF (10–31°C). Dependingupon the features available in the modelof sensor selected, the zone sensor mayrequire from a 2-wire to a 5-wireconnection. Wireless zone sensorsreport the same zone information aswired zone sensors, but do so usingradio transmitter technology. Thereforewith wireless, wiring from the zonesensor to the UCM is unnecessary.

SelectionProcedure
This section describes the elementsand process required to properly selectparallel fan-powered VAV terminals,and includes a specific example. Theselection procedure is iterative innature which makes computerselection desirable.
Selection of fan-powered VAVterminals involves four elements:
Air valve selectionHeating coil selectionFan size and selectionAcoustics
Air Valve Selection
Provided in the performance datasection of the catalog is the wide-openair pressure drop vs. airflow curve. Toselect an air valve, locate the requireddesign cooling airflow and find itsvertical intersection with the smallestair valve size that has air pressure dropequal to or lower than the maximumwide-open air pressure droprequirement.
Heating Coil Selection
Supply Air TemperatureThe first step required when selecting aheating coil is to determine the heatingsupply air temperature to the space,calculated using the heat transferequation. Air temperature difference isdefined as the heating supply airtemperature to the space minus thewinter room design temperature. Thezone design heat loss rate is denotedby the letter Q. Supply air temperatureto the space equals the leaving airtemperature (LAT) for the terminal unit.
Coil Leaving Air TemperatureOnce the terminal unit LAT isdetermined, the heating requirementsfor the coil can be calculated. Theleaving air temperature for the coil of aparallel fan-powered terminal unitvaries based on the type of unitinstalled heat being selected.
Electric coil LAT equals terminal unitLAT because the coil is located on theunit discharge. Hot water coils,however, are located on the enteringair side of the fan. In this case, coil LATis calculated using a mixing equation.Given the unit heating airflow and LAT,minimum primary airflow at its supplyair temperature, and the volume ofheated plenum air, the leaving airtemperature for the hot water coil canbe determined (see the unit selectionexample that follows for more details).
Coil Entering Air TemperatureThe entering air temperature (EAT) tothe coil also varies based on the coilposition on the unit.
Electric coil EAT equals thetemperature of blended primary airand plenum air because the coil is in ablow-thru configuration. The unit hotwater coil configuration is draw-thru,therefore, EAT equals the plenumair temperature.
Capacity RequirementOnce both coil EAT and LAT aredetermined, the heat transfer (Q) forthe coil must be calculated using theheat transfer equation. For electric heatunits, the Q value must be convertedfrom Btu to kW for heater selection.The required kW should be comparedto availability charts in the performancedata section for the unit selected. Forhot water heat units, reference thecapacity charts in the performance datasection for the required heat transfer Qand airflow to pick the appropriate coil.
Fan Size and Selection
Fan AirflowFan airflow is determined bycalculating the difference betweenthe unit design heating airflow andminimum primary airflow.
Fan External Static PressureFan external static pressure is the totalresistance experienced by the fan,which may include downstreamductwork and diffusers, heating coils,and sound attenuators. As total airflowvaries so will static pressure, makingcalculation of external static pressuredependent on unit type.
In many applications of parallelterminals, a minimum primary airflowmust be maintained to meetventilation requirements. This primaryairflow contributes to the totalresistance experienced by the fan andshould be accounted for in allcomponents downstream of the fanitself, including electric coils. Hot watercoils are positioned on the fan inlet andare not affected by the additionalprimary airflow. The static pressureresistance experienced by the fan dueto the hot water coil is based on fanairflow only, not the totalheating airflow.
SelectionOnce fan airflow and external staticpressure are determined, reference thefan curves in the performance datasection. Cross plot both airflow andexternal static pressure on eachapplicable graph. A selection betweenthe minimum and maximum airflowranges for the fan is required.
It is common to identify more thanone fan that can meet the designrequirements. Typically, selectionbegins with the smallest fan availableto meet capacity. If this selectiondoes not meet acousticalrequirements, upsizing the fan andoperating it at a slower speed can bedone for quieter operation.
Acoustics
Air Valve Generated NoiseTo determine the noise generated bythe air valve, two pieces of informationare required; design airflow and designair pressure drop. The design airpressure drop is determined by takingthe difference between design inletand static pressure (the valve’s mostover-pressurized condition) andexternal static pressure at designcooling flow. This represents a worst-case operating condition for the valve.

VAV-PRC008-ENFPP 6
SelectionProcedure
Fan Generated NoiseTo determine fan noise levels, fanairflow, external static pressure andspeed information is required.
Evaluation ElementsFor parallel fan-powered terminal units,the air valve and fan operation must beevaluated separately because theseoperations are not simultaneous.
Access the appropriate acousticstable(s) of the catalog and determinethe sound power and NC prediction forboth the discharge and radiated paths. Itis important to understand thatdischarge air noise is generally not aconcern with fan-powered terminals.Radiated noise from the unit casingtypically dictates the noise level ofthe space.
If the entire unit or any element of it isgenerating noise in excess of the NoiseCriteria requirements, the size of theappropriate portion of the terminalshould be increased. Because theselection procedure is iterative, careshould be taken by the designer toconfirm that the change in selectiondoes not affect other elements of theunit or system design.
Selection Example—
Parallel With Hot Water Heat
Air Valve SelectionRequired Information:
Design cooling airflow: 1000 cfmMaximum wide-openair pressure drop: 0.25 in. wg
Choose a size 10 air valve with wide-open air pressure drop of 0.05 in. wg
Heating Coil SelectionRequired Information:
Zone design heat loss: 20000 BtuUnit heating airflow: 600 cfmWinter room design temp.: 68ºFCoil entering water temp.: 180ºFMinimum primary airflow: 200 cfmPlenum temperature: 70ºFCoil flow rate: 2 gpmPrimary air temperature: 55ºF
Heat Transfer Equation (Btu)Q = 1.085 x Cfm x D Temperature
For the heating zone, the temperaturedifference is the zone supply airtemperature (SAT) minus the winterroom design temperature.
20000 Btu = 1.085 x 600 x (SAT - 68ºF)SAT = 98ºF
Because the hot water coil is on theplenum inlet of a parallel fan-poweredunit, the unit supply air temperature isequal to the mix of the heated plenumair from the fan and the minimumprimary airflow.
600 cfm x 98ºF =200 cfm x 55ºF +(600 cfm - 200 cfm) x Coil LAT
Coil LAT = 121ºF
For the heating coil, the temperaturedifference is the calculated coil LATminus the coil EAT (Plenum AirTemperature).Coil Q = 1.085 x 400 x (121-70) =
22134 Btu = 22.13 Mbh
Coil Performance TableSelection:Size 02 fan, 2-row coil with 2 gpm =30.02 Mbh
2-row coil with 2 gpm = 9.15 ft WPD
Fan SelectionRequired Information:
Design airflow: 400 cfmDownstream static pressureat design airflow: 0.25 in. wg
Fan external static pressure equalsdownstream static pressure (ductworkand diffusers) plus coil static pressure.The coil static pressure that the fanexperiences is at the fan airflow(400 cfm). The downstream staticpressure the fan experiences is at fanairflow plus minimum primary airflow.The sum of fan airflow and minimumprimary airflow (600 cfm) is less thandesign airflow (1000 cfm) and thereforethe 0.25 in. wg downstream staticpressure at design airflow must beadjusted for the lower heating airflow.
Using Fan Law Two:Heating Downstream Static Pressure =(600/1000)2 x 0.25 = .09 in. wg
A size 02 fan has the capability to deliverapproximately 650 cfm at 0.09downstream static pressure.
If an attenuator is required, use theattenuator air pressure drop tables todefine additional fan static pressure.
AcousticsRequired Information:
Design inlet static press.: 1.0 in. wgNC criteria: NC-35
The selection is a VPWF Parallel Fan-powered Terminal Unit, primary air valvesize 10, parallel fan size 02, with a 2-rowhot water coil.
Determine the casing radiated noiselevel because it typically dictates thesound level (NC) of the space. With aparallel unit, two operating conditionsmust be considered, design cooling anddesign heating.

If the catalog pathattenuation assumptions areacceptable, this unit meets all of thedesign requirements and the selectionprocess is complete.Computer SelectionThe advent of personal computershas served to automate manyprocesses that were previouslyrepetitive and time-consuming. Oneof those tasks is the proper scheduling,sizing, and selection of VAV terminalunits. Trane has developed a computerprogram to perform these tasks. Thesoftware is called the Trane OfficialProduct Selection System (TOPSS).The TOPSS program will take the inputspecifications and output the properlysized VariTrane VAV terminal unit alongwith the specific performance for thatsize unit.The program has several requiredfields, denoted by red shading in theTOPSS screen, and many otheroptional fields to meet the criteria youhave. Required values includemaximum and minimum airflows,control type, and model. If selectingmodels with reheat, you will berequired to enter information to makethat selection also. The user is giventhe option to look at all the informationfor one selection on one screen or as aschedule with the other VAV units onthe job.The user can select single-duct, dual-duct, and fan-powered VAV boxes withthe program, as well as most otherTrane products, allowing you to selectall your Trane equipment with onesoftware program.The program will also calculate soundpower data for the selected terminalunit. The user can enter a maximum

Notes:1. Electric Heat Units - Units with fan sizes 01 to 0517 and a primary
voltage of 208/60/1, 208/60/3, or 240/60/1 have 115/60/1 VAC fanmotors. Fan sizes 06 and 07 with the same voltages, have208/60/1 VAC motors.
2. Electric Heat Units - Units with primary voltage of 277/60/1,480/60/1 or 480/60/3 use 277 VAC fan motors.
3. Electric Heat Units - Units with primary voltage of 347/60/1 or575/60/3 use 347 VAC fan motors.
4. With 380/50/3 and 230/50/1, use 230/50 motors.
Minimum Circuit Ampacity (MCA) EquationMCA = 1.25 x (Σ motor amps + heater amps)Motor amps is the sum of all motor current draws if morethan one is used in the unit.
Maximum Overcurrent Protection (MOP) EquationMOP = (2.25 x motor1 amps) + motor2 amps + heater ampsmotor1 amps = current draw of largest motormotor2 amps = sum of current of all other motors used in unit
General Sizing Rules:If MOP = 15, then fuse size = 15
If MOP = 19, then fuse size = 15 with one exception. If heateramps x 1.25 > 15, then fuse size = 20.
If MOP ≤ MCA, then choose next fuse size greater than MCA.
Control fusing not applicable.
Standard Fuse Sizes: 15, 20, 25, 30, 35, 40, 45, 50, and 60.
Example:
A model VPEF, electric reheat unit size 10-0517 has 480/3 phase, 12 kWelectric reheat with 2 stages and 277-Volt motor.
For MOP of fan-powered unit:
12 kW - 480/3 heater 12 x 1000 = 14.45 amps480 x 1.73
MCA = (2.4 + 14.45) x 1.25 = 21.06, MOP = (2.25 x 2.4) + 14.45 = 19.9.
Since MOP ≤ MCA, then MOP = 25.
For total current draw of unit:
Electric Actuator = 0.17 ampsDDC UCM Control Board = 0.3312 kW—480/3 heater 12 x 1000 = 14.45

UNIT CONTROLS SEQUENCE OFOPERATIONThe unit controller continuouslymonitors the zone temperature againstits setpoint and varies the primaryairflow as required to meet zonesetpoints. Airflow is limited byminimum and maximum position setpoints. For a parallel unit, the controllerwill intermittently start the fan upon acall for heat. Upon a further call forheat, reheat is enabled.
1. Primary Airflow—The fan energizeswhen primary airflow drops belowthe fan setpoint airflow. The fanautomatically starts when the zonetemperature drops to the heatingtemperature setpoint.
2. Zone Temperature—The fanenergizes when the zone temperaturedrops to a selectable number ofdegrees above the heatingtemperature setpoint.
DIRECT DIGITAL CONTROLS
DDC Actuator—Trane 3-wire, 24-VAC, floating-point control actuatorwith linkage release button. Torque is35 in-lb minimum and is non-springreturn with a 90-second drive time.Travel is terminated by end stops atfully-opened and -closed positions. Anintegral magnetic clutch eliminatesmotor stall.
Direct Digital Controller—Themicroprocessor-based terminal unitcontroller provides accurate, pressure-independent control through the useof a proportional integral controlalgorithm and direct digital controltechnology. The controller, named theUnit Control Module (UCM), monitorszone temperature setpoints, zonetemperature and its rate of change,and valve airflow using a differentialpressure signal from the pressuretransducer. Additionally, the controllercan monitor either supply duct airtemperature or CO2 concentration viaappropriate sensors. The controller isprovided in an enclosure with 7/8"(22 mm) knockouts for remote controlwiring. A Trane UCM zone sensoris required.
DDC Zone Sensor—The UCMcontroller senses zone temperaturethrough a sensing element located inthe zone sensor. In addition to thesensing element, zone sensor options
may include an externally-adjustablesetpoint, communications jack for usewith a portable edit device, and anoverride button to change theindividual controller from unoccupiedto occupied mode. The override buttonhas a cancel feature that will return thesystem to unoccupied. Wired zonesensors utilize a thermistor to vary thevoltage output in response to changesin the zone temperature. Wiring to theUCM controller must be 18- to 22-awg.twisted pair wiring. The setpointadjustment range is 50–88ºF (10–31°C).Depending upon the features availablein the model of sensor selected, thezone sensor may require from a 2-wireto a 5-wire connection. Wireless zonesensors report the same zoneinformation as wired zone sensors,but do so using radio transmittertechnology. Therefore with wireless,wiring from the zone sensor to theUCM is unnecessary.
Digital Display Zone Sensor withLiquid Crystal Display (LCD)—The digital display zone sensor containsa sensing element, which sends a signalto the UCM. A Liquid Crystal Display(LCD) displays setpoint or spacetemperature. Sensor buttons allow theuser to adjust setpoints, and allow spacetemperature readings to be turned on oroff. The digital display zone sensor alsoincludes a communication jack for usewith a portable edit device, and anoverride button to change the UCMfrom unoccupied to occupied. Theoverride button has a cancel feature,which returns the system to unoccupiedmode.
System Communications—TheController is designed to send andreceive data from a Tracer Summit™ orother Trane controllers. Current unitstatus conditions and setpoints may bemonitored and/or edited via this datacommunication feature. The networktype is a twisted wire pair shieldedserial communication.

SelectionProcedure
This section describes the elementsand process required to properly selectseries fan-powered VAV terminals, andincludes a specific example. Theselection procedure is iterative innature, which makes computerselection desirable.
Selection of fan-powered VAVterminals involves four elements:
Air valve selectionHeating coil selectionFan size and speed selectionAcoustics
Air Valve Selection
Provided in the performance datasection of the catalog is the Wide OpenAir Pressure Drop vs. Airflow table. Toselect an air valve, locate the requireddesign cooling airflow and find thesmallest air valve size that has airpressure drop equal to or lower thanthe maximum wide-open air pressuredrop requirement.
Heating Coil Selection
Supply Air TemperatureThe first step required when selecting aheating coil is to determine the heatingsupply air temperature to the space,calculated using the heat transferequation. Air temperature difference isdefined as the heating supply airtemperature to the space minus thewinter room design temperature. Thezone design heat loss rate is denotedby the letter Q. Supply air temperatureto the space equals the leaving airtemperature (LAT) for the terminal unit.
Coil Leaving Air TemperatureOnce the terminal unit LAT isdetermined, the heating requirementsfor the coil can be calculated. Electricand hot water coil LAT equals the LATfor the unit because, in each case, thecoil is located on the unit discharge.
Coil Entering Air TemperatureUnit heat is mounted on the dischargeof the unit. Therefore, electric and hotwater coil EAT equals the temperatureof blended primary air and plenum air.
Capacity RequirementOnce both coil EAT and LAT aredetermined, the heat transfer (Q) for thecoil must be calculated using the heattransfer equation. For electric heat units,the Q value must be converted from Btuto kW for heater selection. The requiredkW should be compared to availabilitycharts in the performance data sectionfor the unit selected. For hot water heatunits, reference the capacity charts inthe performance data section for therequired heat transfer Q and airflow topick the appropriate coil.
Fan Size and Motor Selection
Fan AirflowFan airflow is equal to the unit designflow in both heating and cooling modes.
Fan External Static PressureFan external static pressure is the totalresistance experienced by the fan,which may include downstreamductwork and diffusers, heating coils,and sound attenuators. As total airflowvaries, so will static pressure, makingcalculation of external static pressuredependent on unit type.
With series fan-powered terminal units,all airflow passes through the fan.External static pressure requirementsare the sum of the individualcomponent pressure requirements atthe design airflow of the unit.
Fan Motor TypeThe fan motor type that will be used forthe unit will need to be known beforeselection can begin. The ECM motoroffers a wider range of airflows thanthe standard single-speed motor andwill use different fan curves.
Refer to the Features and Benefitssection to determine which motor ismore appropriate for the unit
SelectionOnce fan airflow and external staticpressure is determined, reference thefan curves in the performance datasection. Cross plot both airflow andexternal static pressure on eachapplicable graph. If selecting with anECM motor, make sure you use theECM fan curves. If the point is inbetween the high and low limits of thegraph, that fan will work.
It is common to identify more than onefan that can meet the designrequirements. Typically selectionbegins with the smallest fan availableto meet capacity. If this selection doesnot meet acoustical requirements,upsizing the fan and operating it at aslower speed can be done for quieteroperation.
Acoustics
Air Valve Generated NoiseTo determine the noise generated bythe air valve, two pieces of informationare required; design airflow and designair pressure drop. The design airpressure drop is determined by takingthe difference between design inletand static pressure (the valve’s mostover-pressurized condition) andexternal static pressure at designcooling flow. This represents a worst-case operating condition for the valve.
Fan Generated NoiseTo determine fan noise levels, fanairflow, external static pressure andspeed information is required.
Evaluation ElementsAir valve and fan are evaluatedtogether because they havesimultaneous operation.

The selection is a VSWE Series Fan-Powered Terminal Unit, primary airvalve size 12, series fan size 0417, witha 1-row hot water coil.
Determine the casing radiated noiselevel because it typically dictates thesound level (NC) of the space. With aseries unit, the air valve and fanoperate simultaneously, so the chartfor air valve and fan sound data mustbe consulted.

The predicted NC level for designconditions is NC-35.
Note: Make sure the water coilacoustical impact is considered. Forthis example, the appurtenance effectadds one (1) NC to fan-only radiatedsound. Because this does not set NCfor this selection, it can be overlooked.The addition of an attenuator (seesame appurtenance effect tablesreduces the NC five (5) points, resultingin a final selection NC = 30 (if required).
Caution: Do not overlook the water coilimpact on acoustics. A good rule ofthumb is that it will add 1 to 2 NC to"fan only" radiated sound for mostapplications.
SelectionProcedure
Access the appropriate acousticstable(s) of the catalog and determinethe sound power and NC predictionfor both the discharge and radiatedpaths. It is important to understandthat discharge air noise is generallynot a concern with fan-poweredterminals. Radiated noise from theunit casing typically dictates the noiselevel of the space.
If the entire unit or any element of it isgenerating noise in excess of the NoiseCriteria requirements, the size of theappropriate portion of the terminalshould be increased. Because theselection procedure is iterative, careshould be taken by the designer toconfirm that the change in selectiondoes not affect other elements of theunit or system design.
Selection Example—Series With Hot Water Heat and ECM
Air Valve SelectionRequired Information:
Design cooling airflow 1000 cfmMaximum wide-openair pressure drop 0.25 in. wg
The 0417 fan will be used in thisinstance. By interpolating, you canchoose a size 12 air valve with wide-open air pressure drop of 0.22 in. wg.
Heating Coil SelectionRequired Information:
Zone design heat loss 35000 BtuDesign heating airflow 1000 cfmWinter room design temp. 68ºFCoil entering water temp. 180ºFMinimum primary airflow 250 cfmPlenum temperature 75ºFPrimary air temperature 55ºFCoil flow rate: 3 gpm
Heat Transfer Equation (Btu)Q = 1.085 x Cfm x ∆ Temperature
For the heating zone, the temperaturedifference is the zone supply airtemperature (SAT) minus the winterroom design temperature.
35000 Btu = 1.085 x 1000 x (SAT-68°F)
SAT = 100ºF
Because the hot water coil is on theunit discharge of a series fan-poweredunit, the unit supply air temperature isequal to the coil LAT. Coil entering airtemperature (EAT) is a mix of plenumair and the minimum primary airflow.
1000 cfm x Coil EAT =250 cfm x 55ºF +(1000 cfm - 250 cfm) x 75ºF
Coil EAT = 70ºF
For the heating coil, the temperaturedifference is the calculated coil LATminus the coil EAT (Plenum AirTemperature).
Coil Q = 1.085 x 1000 x (100-70) = 32550 Btu
On a series unit the hot water coil islocated on the discharge, so the totalheating airflow, 1000 cfm, passesthrough the coil.
Coil Performance TableSelection:Performance:Size 0417 fan, 1-row coil at 3 gpm =35.66 MBh1-row Coil at 3 gpm= 1.78 ft WPD
Fan SelectionRequired Information:Fan airflow: 1000 cfmDownstream static pressureat design airflow: 0.25 in. wg
A size 0417 fan with cfm can operate atup to 1600 cfm with a 1-row coil or1540 with a 2-row coil and 0.25"downstream static pressure. Inlet andcoil selections would need to beverified.
If an attenuator is required, use theattenuator air pressure drop tables todefine additional fan static pressure.

SelectionProcedure
Rearrange what fields you seeand in what order with a fewclicks of a button.
Required entry fields (in Redon TOPSS screen).
NOTE: Use the same procedures for selecting Low-Height Series Fan-Powered Unitsas used for selecting Series Fan-Powered Units
Computer SelectionThe advent of personal computers hasserved to automate many processesthat were previously repetitive andtime-consuming. One of those tasks isthe proper scheduling, sizing, andselection of VAV terminal units. Tranehas developed a computer program toperform these tasks. The software iscalled the Trane Official ProductSelection System (TOPSS).
The TOPSS program will take the inputspecifications and output the properlysized VariTrane VAV terminal unit alongwith the specific performance for thatsize unit.
The program has several requiredfields, denoted by red shading in theTOPSS screen, and many otheroptional fields to meet the criteria youhave. Required values includemaximum and minimum airflows,control type, and model. If selectingmodels with reheat, you will berequired to enter information to makethat selection also. The user is giventhe option to look at all the informationfor one selection on one screen or as aschedule with the other VAV units onthe job.
The user can select single-duct, dual-duct, and fan-powered VAV boxes withthe program, as well as most otherTrane products, allowing you to selectall your Trane equipment with onesoftware program.
The program will also calculate soundpower data for the selected terminalunit. The user can enter a maximumindividual sound level for each octaveband or a maximum NC value. Theprogram will calculate acoustical datasubject to default or user suppliedsound attenuation data.
Schedule ViewThe program has many time-saving features such as:Copy/Paste from spreadsheets like Microsoft® ExcelEasily arranged fields to match your scheduleTime-saving templates to store default settings
The user can also export the Schedule View to Excel to modify and put into a CADdrawing as a schedule.
Specific details regarding the program, its operation, and how to obtain a copy of itare available from your local Trane sales office.

Notes:1. Electric Heat Units—Units with fan sizes 01 to 0517 and a primary
voltage of 208/60/1, 208/60/3 or 0/60/1 use 115/60/1 VAC fan motors. Fansizes 06 and 07 in these same voltages, have 208/60/1 VAC fan motors.
2. Electric Heat Units—Units with primary voltage of 277/60/1, 480/60/1 or480/60/3 use 277 VAC fan motors.
3. Electric Heat Units—Units with primary voltage of 347/60/1 or 575/60/3use 347 VAC fan motors.
4. With 380/50/3 and 230/50/1 use 230/50 motors.
Minimum Circuit Ampacity (MCA) EquationMCA = 1.25 x (Σmotor amps + heater amps)Here motor amps is the sum of all motor current draws if morethan one is used in the unit.
Maximum Overcurrent Protection (MOP) EquationMOP = (2.25 x motor 1amps) + motor2 amps + heater ampsmotor1 amps = current draw of largest motormotor2 amps = sum of current draw of all other motors used in units
General Sizing Rules:If MOP = 15, then fuse size = 15
If MOP = 19, then fuse size = 15 with one exception. If heateramps x 1.25 > 15, then fuse size = 20.
If MOP ≤ MCA, then choose next fuse size greater than MCA.
Control fusing not applicable.
Standard Fuse Sizes: 15, 20, 25, 30, 35, 40, 45, 50, and 60.

Useful formulas:
Example:
A model VSEF, electric reheat unit size 10-0517 has 480/3 phase, 12 kWelectric reheat with 2 stages and 277-Volt motor.
For MOP of fan-powered unit:
12 kW - 480/3 heater 12 x 1000 = 14.45 amps480 x 1.73
MCA = (2.4 + 14.45) x 1.25 = 21.06, MOP = (2.25 x 2.4) + 14.45 = 19.9.
Since MOP ≤ MCA, then MOP = 25.
For total current draw of unit:
Electric Actuator = 0.17 ampsDDC UCM Control Board = 0.3312 kW—480/3 heater 12 x 1000 = 14.45
480 x 1.73Two heat outputs (2 stages) @0.5 amps max each = 1.00Motor amps: 277 V (Fan size 0517) = 2.4

ECM Data—Fan Curves(60 Hz only)
Notes:1. Acceptable selections are any point within the shaded area. The ECM will operate on a vertical performance line using the solid state speed controller provided.2. The ECM motor provides constant volume with changing static pressure conditions. Therefore, the fan curves for the ECM are different compared to fan curves with
PSC motors.3. By using an ECM motor, less fan sizes are used because of the wider turn-down ratios.

DDC Actuator—Trane 3-wire,24-VAC, floating-point control actuatorwith linkage release button. Torque is35 in-lb minimum and is non-springreturn with a 90-second drive time.Travel is terminated by end stops atfully opened and closed positions. Anintegral magnetic clutch eliminatesmotor stall.Direct Digital Controller—Themicroprocessor based terminal unitcontroller provides accurate, pressure-independent control through the useof a proportional integral controlalgorithm and direct digital controltechnology. The controller, named theUnit Control Module (UCM), monitorszone temperature setpoints, zonetemperature and its rate of change,and valve airflow using a differentialpressure signal from the pressuretransducer. Additionally, the controllercan monitor either supply duct airtemperature or CO2 concentration viaappropriate sensors. The controller isprovided in an enclosure with 7/8"(22 mm) knockouts for remote controlwiring. A Trane UCM zone sensor isrequired.DDC Zone Sensor—The UCMcontroller senses zone temperaturethrough a sensing element located inthe zone sensor. In addition to thesensing element, zone sensor optionsmay include an externally-adjustablesetpoint, communications jack for usewith a portable edit device, and anoverride button to change theindividual controller from unoccupiedto occupied mode. The override buttonhas a cancel feature that will return thesystem to unoccupied. Wired zonesensors utilize a thermistor to vary thevoltage output in response to changes
in the zone temperature. Wiring to theUCM controller must be 18- to 22-awg.twisted pair wiring. The setpointadjustment range is 50–88ºF (10–31°C).Depending upon the features availablein the model of sensor selected, thezone sensor may require from a 2-wireto a 5-wire connection. Wireless zonesensors report the same zoneinformation as wired zone sensors, butdo so using radio transmittertechnology. Therefore with wireless,wiring from the zone sensor to theUCM is unnecessary.Digital Display Zone Sensor withLiquid Crystal Display (LCD)—The digital display zone sensorcontains a sensing element, whichsends a signal to the UCM. A LiquidCrystal Display (LCD) displays setpointor space temperature. Sensor buttonsallow the user to adjust setpoints, andallow space temperature readings tobe turned on or off. The digital displayzone sensor also includes acommunication jack for use with aportable edit device, and an overridebutton to change the UCM fromunoccupied to occupied. Theoverride button has a cancel feature,which returns the system tounoccupied mode.

Notes:1. Electric Heat Units - Units with Primary Voltage of 208/60/1, 208/
60/3 or 240/60/1 use 115 VAC fan motors.2. Electric Heat Units - Units with Primary Voltage of 277/60/1,
480/60/1 or 480/60/3 use 277 VAC fan motors.3. Electric Heat Units - Units with Primary Voltage of 347/60/1 or
575/60/3 use 347 VAC fan motors.4. Values are for standard, single-speed, permanent split capacitor
type motors. Consult factory for non-standard motorperformance.
Minimum Circuit Ampacity (MCA) EquationMCA = (motor amps + heater amps) x 1.25
Maximum Overcurrent Protection (MOP) EquationMOP = (2.25 x motor amps) + heater amps
General Sizing Rules:If MOP = 15, then fuse size = 15
If MOP = 19, then fuse size = 15 with one exception. If heateramps x 1.25 > 15, then fuse size = 20.
If MOP ≤ MCA, then choose next fuse size greater than MCA.
Control fusing not applicable.
Standard Fuse Sizes: 15, 20, 25, 30, 35, 40, 45, 50, and 60.

UNIT CONTROLS SEQUENCE OFOPERATIONThe controller continuously monitorsthe zone temperature against itssetpoint and varies the primary airflowas required to meet zone setpoints.Airflow is limited by minimum andmaximum setpoints. For a low-heightparallel unit, the controller willintermittently start the fan upon a callfor heat. Upon a further call for heat,any hot water or electric heatassociated with the unit is enabled.
1. Primary Airflow—The fan energizeswhen primary airflow drops belowthe fan setpoint airflow. The fanautomatically starts when the zonetemperature drops to the heatingtemperature setpoint.
2. Zone Temperature—The fanenergizes when the zone temperaturedrops to a selectable number ofdegrees above the heatingtemperature setpoint.
DIRECT DIGITAL CONTROLS
DDC Actuator—Trane 3-wire,24-VAC, floating-point control actuatorwith linkage release button. Torque is35 in-lb minimum and is non-springreturn with a 90-second drive time.Travel is terminated by end stops atfully-opened and -closed positions. Anintegral magnetic clutch eliminatesmotor stall.
Direct Digital Controller—Themicroprocessor based terminal unitcontroller provides accurate, pressure-independent control through the useof a proportional integral controlalgorithm and direct digital controltechnology. The controller, named theUnit Control Module (UCM), monitorszone temperature setpoints, zonetemperature and its rate of change,and valve airflow using a differentialpressure signal from the pressuretransducer. Additionally, the controllercan monitor either supply duct airtemperature or CO2 concentration viaappropriate sensors. The controller isprovided in an enclosure with 7/8"(22 mm) knockouts for remote controlwiring. A Trane UCM zone sensoris required.
DDC Zone Sensor—The UCMcontroller senses zone temperaturethrough a sensing element located inthe zone sensor. In addition to thesensing element, zone sensor optionsmay include an externally-adjustablesetpoint, communications jack for usewith a portable edit device, and anoverride button to change theindividual controller from unoccupiedto occupied mode. The override buttonhas a cancel feature that will return thesystem to unoccupied. Wired zonesensors utilize a thermistor to vary thevoltage output in response to changesin the zone temperature. Wiring to theUCM controller must be 18- to 22-awg.twisted pair wiring. The setpointadjustment range is 50–88ºF (10–31°C).Depending upon the features availablein the model of sensor selected, thezone sensor may require from a 2-wireto a 5-wire connection. Wireless zonesensors report the same zoneinformation as wired zone sensors,but do so using radio transmittertechnology. Therefore with wireless,wiring from the zone sensor to theUCM is unnecessary.

Notes:1. Coils available with 24 VAC magnetic or mercury contactors, load carrying P.E. switches, and P.E. switch with magnetic or mercury contactors.2. Available kW increments are by 0.5 from 0.5 kW to 8.0 kW and by 1.0 kW from 9.0 to 18.0 kW.3. Each stage will be equal in kW output.4. All heaters contain an auto thermal cutout and a manual reset cutout.5. The current amp draw for the heater elements is calculated by the formula below.6. Only two stages of electric reheat available with Trane controls.
Notes:1. Electric Heat Units - Units with Primary Voltage of 208/60/1,
208/60/3 or 240/60/1 use 115 VAC fan motors.2. Electric Heat Units - Units with Primary Voltage of 277/60/1,
480/60/1 or 480/60/3 use 277 VAC fan motors.3. Electric Heat Units - Units with Primary Voltage of 347/60/1 or
575/60/3 use 347 VAC fan motors.4. Values are for standard, single-speed, permanent split capacitor
type motors. Consult factory for non-standard motorperformance.
Minimum Circuit Ampacity (MCA) EquationMCA = (motor amps + heater amps) x 1.25
Maximum Overcurrent Protection (MOP) EquationMOP = (2.25 x motor amps) + heater amps
General Sizing Rules:If MOP = 15, then fuse size = 15
If MOP = 19, then fuse size = 15 with one exception. If heateramps x 1.25 > 15, then fuse size = 20.
If MOP ≤ MCA, then choose next fuse size greater than MCA.
Control fusing not applicable.
Standard Fuse Sizes: 15, 20, 25, 30, 35, 40, 45, 50, and 60.

DIRECT DIGITAL CONTROLS
DDC Actuator—Trane 3-wire,24-VAC, floating-point control actuatorwith linkage release button. Torque is35 in-lb minimum and is non-springreturn with a 90-second drive time.Travel is terminated by end stops atfully-opened and -closed positions. Anintegral magnetic clutch eliminatesmotor stall.
Direct Digital Controller—Themicroprocessor based terminal unitcontroller provides accurate, pressure-independent control through the useof a proportional integral controlalgorithm and direct digital controltechnology. The controller, named theUnit Control Module (UCM), monitorszone temperature setpoints, zonetemperature and its rate of change,and valve airflow using a differentialpressure signal from the pressuretransducer. Additionally, the controllercan monitor either supply duct airtemperature or CO2 concentration viaappropriate sensors. The controller isprovided in an enclosure with 7/8"(22 mm) knockouts for remote controlwiring. A Trane UCM zone sensor isrequired.
DDC Zone Sensor—The UCMcontroller senses zone temperaturethrough a sensing element located inthe zone sensor. In addition to thesensing element, zone sensor optionsmay include an externally-adjustablesetpoint, communications jack for usewith a portable edit device, and an
override button to change the individualcontroller from unoccupied to occupiedmode. The override button has a cancelfeature that will return the system tounoccupied. Wired zone sensors utilizea thermistor to vary the voltage outputin response to changes in the zonetemperature. Wiring to the UCMcontroller must be 18- to 22-awg.twisted pair wiring. The setpointadjustment range is 50–88ºF (10–31°C).Depending upon the features availablein the model of sensor selected, thezone sensor may require from a 2-wireto a 5-wire connection. Wireless zonesensors report the same zoneinformation as wired zone sensors, butdo so using radio transmittertechnology. Therefore with wireless,wiring from the zone sensor to the UCMis unnecessary.
Digital Display Zone Sensor withLiquid Crystal Display (LCD)—Thedigital display zone sensor contains asensing element, which sends a signalto the UCM. A Liquid Crystal Display(LCD) displays setpoint or spacetemperature. Sensor buttons allow theuser to adjust setpoints, and allow spacetemperature readings to be turned on oroff. The digital display zone sensor alsoincludes a communication jack for usewith a portable edit device, and anoverride button to change the UCMfrom unoccupied to occupied. Theoverride button has a cancel feature,which returns the system tounoccupied mode.
System Communications—TheController is designed to send andreceive data from a Tracer Summit™ orother Trane controllers. Current unitstatus conditions and setpoints may bemonitored and/or edited via this datacommunication feature. The networktype is a twisted wire pair shielded serialcommunication.

GeneralLogic
Trane DDC–UCM operate in a pressure-dependent (PD)mode of operation.Cooling and heating control action ofair valve. In cooling control action, theDDC controller matches cooling airflowto cooling load. In heating controlaction, the DDC controller matches theheating airflow to control heating load.The DDC controller will automaticallychange over to cooling control action ifthe supply air temperature is below theroom temperature and willautomatically change over to heatingcontrol action if the supply airtemperature is 10°F or more above theroom temperature. If the supply airtemperature is between the roomtemperature and the roomtemperature plus 10°F, then the DDCcontroller will provide the activeminimum airflow. The DDC controllerfirst chooses the Tracer Summit-supplied supply air temperature valueto use for auto changeover. If this is notavailable, it uses the temperatureprovided by the optional auxiliarytemperature sensor. If this is also notavailable, it uses the heating/coolingmode assigned by Tracer Summit orthe DDC controller’s service tool(Everyware TM or Rover TM V4).Multiple reheat control optionsincluding staged electric, staged hot-water (normally on or normally off),proportional hot-water, and slowpulsed width modulation. Modulating
reheat options utilize a separate reheatproportional-plus-integral control loopfrom that controlling airflow into theroom. Staged reheat options utilize acontrol algorithm based on heatingsetpoint and room temperature.24 VAC binary input that can beconfigured as a generic input or asoccupancy input. When the DDCcontroller is operation with TracerSummit, the status of the input isprovided to Tracer Summit for itsaction. In stand-alone operation andwhen configured for an occupancyinput, the input will control occupancystatus of the DDC controller.Auxiliary temperature analog inputthat can be configured for an auxiliarytemperature sensor or a 2-to-10 VDCCO2 sensor. When configured fortemperature, the value of the input isused as status-only by Tracer Summit ifTracer Summit is providing a supply airtemperature to the DDC controller.Otherwise, the input will be used fordetermining control action of the DDCcontroller. When configured for a CO2sensor, the value of the input is used asa status-only input by Tracer Summit.Dual-duct support with two DDCcontrollers. One DDC controllercontrols the cooling air valve and theother controller controls the heating airvalve. With constant-volumesequences, the discharge air volume isheld constant by controlling dischargeair volume with the heating UCM.
Control Logic—DDC controllers are today’s industrystandard. DDC controllers providesystem-level data used to optimizesystem performance. Variables such asoccupied/unoccupied status, minimumand maximum airflow setpoints,temperature and temperaturesetpoints, valve position, fan status (onor off, and mode of operation: series orparallel), reheat status (on or off), boxtype and air valve size, temperaturecorrection offsets, flow correctionvalues, ventilation fraction, etc. areavailable on a simple twisted-shieldedwire pair.
Trane DDC controllers provide Trane-designed, solid-state electronicsintended specifically for VAVtemperature control in space comfortapplications. DDC control capabilitiesinclude:Proportional plus integral control loopalgorithm for determining requiredairflow needed to control roomtemperature. Airflow is limited byactive minimum and maximumairflow setpoints.Pressure-independent (PI) operation,which automatically adjusts valveposition to maintain required airflow.In certain low-flow situations or incases where the flow measurementhas failed, the DDC controller will

DDCReheatControl
DDC Remote HeatControl OptionsWhen heat is added to the primary airat the VAV unit before it enters thezone, the air is said to be reheated. Theoperating characteristics of the fourbasic types of VariTrane DDC terminalreheat are discussed.
Single-Duct: On/Off Hot WaterReheat—Three stages of on/off hotwater reheat are available. The watervalves used are 2-position and areeither fully-opened or fully-closed. Theheating minimum airflow setpoint isenabled during reheat.
Stage 1 energizes when the spacetemperature is at or below the heatingsetpoint. When the zone temperaturerises above the active heating setpointby 0.5°F (0.28°C), stage 1 is de-energized. Stage 2 energizes when thespace temperature is 1°F (0.56°C) ormore below the active heatingsetpoint, and is de-energized when thespace temperature is 0.5°F (0.28°C)below the active heating setpoint.Stage 3 energizes when the zonetemperature is 2°F (1.11°C) or morebelow the active heating setpoint, andde-energizes when the spacetemperature is 1.5°F (0.83°C) below theactive heating setpoint. When reheat isde-energized, the cooling minimumairflow setpoint is activated.
Single-Duct: Proportional HotWater Reheat—Proportional hotwater reheat uses 3-wire floating-point-actuator technology. The heatingminimum airflow setpoint is enabledduring reheat.
The water valve opens as spacetemperature drops below the heatingsetpoint. Water valve position isdependent on both the degree thatspace temperature is below the activeheating setpoint and the time that thespace temperature has been below theactive heating setpoint. If not alreadyclosed, the water valve fully closeswhen the zone temperature risesabove the active heating setpoint by0.5 °F (0.28 °C). An additional on/offremote heat output is available andenergized when the proportional valveis driven 100% open and de-energizedwhen the proportional valve reaches50% open. When reheat is de-energized, the cooling minimumairflow setpoint is activated.
Single-Duct: On/Off ElectricReheat—Three stages of stagedelectric reheat are available. Theheating minimum airflow setpoint isenabled during reheat.
Stage 1 is energized when the spacetemperature falls below the activeheating setpoint and minimum airflowrequirements are met. When the zone
temperature rises above the activeheating setpoint by 0.5°F (0.28°C),stage 1 is de-energized. Stage 2energizes when the space temperatureis 1°F (0.56°C) or more below the activeheating setpoint, and is de-energizedwhen the space temperature is 0.5°F(0.28°C) below the active heatingsetpoint. Stage 3 energizes when thezone temperature is 2°F (1.11°C) ormore below the active heatingsetpoint, and de-energizes when thespace temperature is 1.5°F (0.83°C)below the active heating setpoint.When reheat is de-energized, thecooling minimum airflow setpoint isactivated.
Single-Duct: Pulse-WidthModulation of Electric Heat—Electric heat is modulated byenergizing for a portion of a three-minute time period. The heatingminimum airflow setpoint is enabledduring reheat. This allows exact loadmatching for energy efficientoperation, and optimum zonetemperature control. One or twostages can be used.
The amount of reheat supplied isdependent on both the degree thatspace temperature is below the activeheating setpoint and the time that thespace temperature has been below theactive heating setpoint. If not alreadyoff, reheat de-energizes when the zonetemperature rises more than 0.5°F(0.28°C) above the heating setpoint.
The Stage 1 “on” time is proportionalto the amount of reheat required. Forexample, when 50% of stage 1capacity is required, reheat is on for 90seconds and off for 90 seconds. When75% of stage 1 capacity is required,reheat is on for 135 seconds and off for45 seconds. When 100% of stage 1capacity is required, reheat is oncontinuously.
Stage 2 uses the same “on” time logicas stage 1 listed above, except stage 1is always energized. For example,when 75% of unit capacity is required,stage 1 is energized continuously, andstage 2 is on for 90 seconds and off for90 seconds. When reheat is de-energized, the cooling minimumairflow setpoint is activated.

The wall- and duct-mounted carbon dioxide (CO2) sensors are designed for use withTrane DDC/UCM control systems. Installation is made simple by attachment directlyto the DDC/ UCM controller. This allows the existing communication link to be usedto send CO2 data to the higher-level Trane control system.
Wall-mounted sensors can monitor individual zones, and the duct-mounted sensoris ideal for monitoring return air of a given unit. Long-term stability and reliabilityare assured with advanced silicon based Non-Dispersive Infrared(NDIR) technology.
When connected to a building automation system with the appropriate ventilationequipment, the Trane CO2 sensors measure and record carbon dioxide in parts-per-million (ppm) in occupied building spaces. These carbon dioxide measurements aretypically used to identify under-ventilated building zones and to override outdoorairflow beyond design ventilation rates if the CO2 exceeds acceptable levels.

An analog signal from the zone sensor is used to compare the difference in the zone temperature and the zonesetpoint. On a rise in zone temperature above the setpoint, the controller outputs a 24-VAC signal, compensated forchanging duct pressures, to open the air valve and to increase primary cooling airflow. Upon a decrease in zonetemperature, the opposite action occurs. Minimum and maximum primary airflow settings are maintained by thecontroller and are adjustable through potentiometers on the controller board. Upon a continued decrease in zonetemperature, below setpoint, the reheat is enabled. For VCCF units with remote hot water reheat and VCWF units,the hot water valve is opened. For VCCF with remote electric reheat and VCEF units, the electric heat stagesare energized.

With an increase in room temperature, the thermostat output pressure is increased. This signal is input for the volume regulator, whichalso receives inputs from the high- and low-pressure sides of the flow ring. The volume regulator outputs a signal compensated forchanging duct pressure to the valve actuator which opens the damper and increases primary cooling flow to the space. With adecrease in room temperature, the opposite action occurs. Minimum and maximum primary airflow settings are maintained by the volume regulator. When the system is designed with reheat, heating stages are energized at the appropriate pressure settings.
With an increase in room temperature, the thermostat output pressure is increased and the actuator opens to increase primarycooling airflow to the space. With a decrease in room temperature, the opposite action occurs.

With a decrease in room temperature, the thermostat output pressure is decreased. This signal is input to the volume regulator, which alsoreceives inputs from the high- and low-pressure sides of the flow ring. The volume regulator outputs a signal compensated for changing ductpressure to the valve actuator, which closes the damper and decreases primary cooling flow to the space. With a further decrease in roomtemperature, the auxiliary limit will override the thermostat signal, which is followed by the reheat being energized. Once the reheat has beenenergized, the volume regulator will send a signal to the actuator to open to its secondary minimum. With an increase in temperature, theopposite action occurs. Minimum and maximum airflow settings are maintained by the volume regulator. Heating stages are energized at theappropriate pressure settings.

With an increase in room temperature, the thermostat output pressure is increased. This signal is input for the volume regulator, which alsoreceives inputs from the high- and low-pressure sides of the flow ring. The volume regulator outputs a signal compensated for changing ductpressure to the valve actuator, which opens the damper and increases primary cooling flow to the space. With a decrease in room temperature,the opposite action occurs. Minimum and maximum primary airflow settings are maintained by the volume regulator. When the system isdesigned with reheat, heating stages are energized at the appropriate pressure settings.

With an increase in room temperature, the thermostat output pressure is increased. This signal is input to the volume regulators,which also receives the inputs from the high- and low-pressure from the flow ring. The cooling volume regulator outputs a signalcompensated for changing duct pressure to the valve actuator, which opens the damper and increases primary cooling airflow to thespace. The heating valve is at a minimum flow. With a decrease in room temperature, the heating valve modulates in response tosignals from the heating pneumatic volume regulator, while maintaining constant volume at the discharge. The heating minimumand maximum settings and the constant volume settings are maintained by the volume regulators.

This unit is energized by sensing inlet static pressure by the duct pressure switch. The unit fan runs continually during occupiedoperation. With an increase in room temperature the thermostat output pressure is decreased. This signal is input to the volume regulator, which also receives the inputs from high- and low-pressure from the flow ring. The volume regulator outputs a signal compensated for changing duct pressures to the valve actuator which opens the damper and increases primary cooling flow to the space. With a decrease in room temperature, the opposite action occurs. Minimum and maximum primary airflow settings are maintained by the volume regulator. If the zone temperature continues to decrease after the fan has been energized, heatingstages are energized at the appropriate pressure settings.

For all VariTrane units, the unitcontroller continuously monitors thezone temperature and varies theprimary airflow as required to meetzone setpoints. Airflow is limited byadjustable minimum and maximumsetpoints.
Additionally for series fan-poweredunits, the controller will start and run thefan continuously during the occupiedmode and intermittently during theunoccupied mode. Upon a further callfor heat, any hot water or electric heatassociated with the unit is enabled.
For parallel fan-powered units, thecontroller energizes the fan upon a callfor heat. Upon a further call for heat,reheat is enabled.
FAN SPEED CONTROL
Variable Speed Control Switch(SCR)—The SCR speed control deviceis standard on all fan-powered units.The SCR adjusts the fanspeed andprovides simplified system balancing.
DIRECT DIGITAL CONTROLS (DDC)
Direct Digital Controller (UCM)—The microprocessor-based terminalunit controller provides accurate,pressure-independent control throughthe use of a proportional integral controlalgorithm and direct digital controltechnology. The Unit Control Module,or UCM, monitors zone temperaturesetpoints, zone temperature, the rateof temperature change, and valveairflow. With the addition of optionalsensors, room occupancy, supply ductair temperature or CO2 can bemonitored. The controller is providedin an enclosure with 7/8" (22 mm)knockouts for remote control wiring.A Trane DDC zone sensor is required.
DDC Actuator—Trane 3-wire, 18-gage, 24-VAC, floating-point controlactuator with linkage release button.Torque is 35 in.-lb minimum and isnon-spring return with a 90-seconddrive time. Travel is terminated by endstops at fully opened and closedpositions. An integral magnetic clutcheliminates motor stall.
DDC Zone Sensor—The UCMcontroller measures zone temperaturethrough a sensing element located inthe zone sensor. Other zone sensoroptions may include an externally-adjustable setpoint, communicationsjack for use with a portable service tool,and an override button to change theindividual controller from unoccupied tooccupied mode. The override button hasa cancel feature that will return the
system to unoccupied. Wired zonesensors utilize a thermistor to vary thevoltage output in response to changes inthe zone temperature. Wiring to theUCM controller must be 18 to 22 awg.twisted pair wiring. The setpointadjustment range is 50–88ºF (10–31°C)Depending upon the features availablein the model of sensor selected, thezone sensor may require from a 2-wireto a 7-wire connection. Wireless zonesensors report the same zoneinformation as wired zone sensors, butdo so using radio transmittertechnology. No wiring from the zonesensor to the UCM controller isnecessary.
Digital Display Zone Sensor withLiquid Crystal Display (LCD)—The direct digital zone sensor contains asensing element which sends a signal tothe UCM. A Liquid Crystal Display (LCD)indicates setpoint, or space temperature.Sensor buttons allow setpoint adjust,and allow space temperature readingsto be turned on or off. The digital displayzone sensor also includes acommunication jack, for use with aportable edit device, and an overridebutton to change the UCM fromunoccupied to occupied. The overridebutton has a cancel feature, whichreturns the system to unoccupied mode.
The digital display zone sensor requiresseven wires, one for 24-VAC power.
System Communications—TheController UCM sends and receives datafrom a Tracer Summit or other TraneController. Current unit status andsetpoints may be monitored and/oredited via this data communicationfeature. The network type is a twistedwire pair shielded serial communication.

DiffusersThe VariTrane line of variable-air-volume (VAV) products has been anindustry leader in performance andquality for many years. While mostwould associate the VariTrane namewith VAV terminal units, the diffuserproduct line has grown significantlyover the years.
Room Air DistributionWhen variable-flow cooling andconstant-flow heating are combined ina zone, the zone air diffusers areusually selected at partial cooling loadto ensure proper operation. Ceiling-mounted linear slot diffusers arerecommended since they perform wellover a wide range of velocities. Cool airdelivery takes advantage of the“Coanda” effect, whereby cool airdischarged through a linear slotdiffuser hugs the ceiling beforedescending, insuring proper operationover a wide range of flows without“dumping.” When delivering warm airwith constant flow velocities, or warm/cool air with variable flow velocities,the flow velocity must be high enoughto ensure that the air reaches the floor.To prevent stratification, the warm airtemperature should not be more than20°F (6.7°C) above the zone airtemperature.
In addition to choosing the correctdiffuser type, the designer mustproperly size and place each diffuser inthe zone to minimize noise andpressure drop while maximizing thethrow and diffusion performance.
VariTrane Diffuser TypesThe VariTrane line of diffusers containsa variety of different models. Thefollowing is a list of the diffuser types
in the VariTrane line,an explanation ofeach type, and a shortdiscussion of theproper application foreach type.
Linear Slot Diffuser(LINR)Linear slot diffusersare most commonlyused in VAV systems.

nominal airflow. If you start by using100% of the nominal airflow, you willend up with high losses inperformance, acoustical problems, andvery little or no design flexibility.
A diffuser airflow rate is 50 cfm perlinear foot (77.4 L/s per linear meter) ofdiffuser. Therefore, the recommendedflow to use when designing is 50 cfm/linear ft x 0.8 = 40 cfm/linear ft (77.4 L/s/linear m x 0.8 = 61.9 L/s/linear m).
The nominal airflow of a diffuser isdetermined by multiplying the diffuserlength, the number of slots, and theairflow per linear foot. Using theairflow per linear foot calculated above,a 4 foot, 2-slot, 2-way diffuser shouldbe designed to handle 4 linear ft x 2slots x 40 cfm/linear ft = 320 cfm(1.219 m x 2 slots x 61.9 L/s/linear m =150.9 L/s).
To maximize the effectiveness ofventilation with ceiling diffusers,throws should be kept as long aspossible. For proper air circulation, tryto maintain at least a 20°F (6.7°C)difference between the supply air androom temperature. This provides foroptimum performance.
Collision Velocities –The collisionvelocity is the speed at which movingair meets a wall or another airflow
This type of diffuser has a fixed vaneinside, which means that the pattern isnot adjustable. The fixed vane allows awide range of flows through thediffuser without causing drafts. Lowerflanges provide ceiling tile support asan integral part of the diffuser housing.
Recommended Guidelines—LinearSlot DiffusersDiffuser Placement – The maximumrecommended distance betweendiffusers is three diffuser lengths. Forexample, if the diffuser length is 4 feet(1.219 m), the maximum separationdistance would be 4 ft x 3 = 12ft(1.219 m x 3 = 3.658 m).
The maximum recommended distancefor diffusers from an exterior wall, withparallel flow to the wall is two diffuserlengths. For example, if the diffuserlength is 4 feet (1.219 m), themaximum distance from the exteriorwall would be 4 ft x 2 = 8 ft(1.219 m x 2 = 2.438 m).
A simple rule for better air circulation isto avoid placing supply air linear slotdiffusers that allow airflows to collideat right angles.
General Guidelines – Whenbeginning the placement and layout ofdiffusers, assume that each diffuserdelivers only 75% to 80% of its

stream. For exterior walls, the collisionvelocity should be between 100 and150 feet per minute (FPM) (0.508 and0.762 m/s). Do not exceed 150 FPM(0.762 m/s) on an exterior wall. Forinterior walls, the collision velocityshould be between 50 and 75 FPM(0.254 and 0.381 m/s). Try not to exceed75 FPM (0.381 m/s) for interior walls.The maximum recommended collisionvelocity between airflow streamsshould not exceed 150 FPM (0.762m/s). The collision velocity betweenairflow streams is determined by theaddition of both velocities at the pointof collision. Avoid collision of airvelocities at right angles to each otherby trying to maintain parallel flow.Following this guideline will allow oneto maximize the "Coanda" effect andproper air diffusion in a zone.Experience indicates that mixed airafter collision near the ceiling andbelow 150 FPM will produce comfort inthe zone at the occupant's level.
Return Air Slots – Return air slotsare placed perpendicular to supply airslots. This prevents supply air frombypassing the space, and allows forproper air circulation. With asuspended ceiling, low operating staticpressure across the ceiling panels mustbe maintained. Failure to do so willcause the return air to be forcedaround the edges of the ceiling panels.When this happens, soiling of thepanels will occur and the mechanicalsystem can become choked for returnair. A space-to-plenum pressure dropof 0.02 to 0.03 inches of water isacceptable under most conditions.

Fully Adjustable Pattern Flow (FAPF) –The FAPF diffuser, a type of ceilingdiffuser outlet, should be used with lay-in ceilings. The primary benefit of thiskind of diffuser is that it provides themost flexibility of adjustment of theairflow pattern. The FAPF diffuserprovides adjustable vanes forhorizontal or vertical throw. The dual-vane option allows each slot to beadjusted for left, right, or vertical throw.Besides pattern adjustments, the vanesalso provide airflow dampering. Inaddition, the vanes are adjustable fromthe face of the diffuser so changes tothe pattern can be made after thediffuser is installed.
Vane Adjustable Pattern Flow (VAPF) –The VAPF diffuser is very similar to theFAPF ceiling outlet diffusers. Theprimary difference is the design of thepattern adjustment vane. The VAPFdiffuser should be used with lay-inceilings. The pattern is adjustable forhorizontal left, horizontal right, orvertical throw. The pattern adjustmentvane contains a felt seal on the end toreduce air leakage around the vane.The vanes are adjustable from the faceof the diffuser, allowing the pattern tobe easily changed after installation.
Vane Adjustable Pattern Flow–Special (VAPS) –The VAPS diffuser is a special versionof the VAPF diffuser. The design of thevane is slightly different from the VAPFmodel, but the VAPS has the samefunctionality. The VAPS has beenpopular in certain regions of thecountry.
Adjustable Air Bar Diffuser (AABD) –The AABD diffuser is another lay-inceiling type of diffuser. The differencebetween the AABD and the FAPF or theVAPF is that the AABD has noadjustment vane. A sliding air bar inthe outlet of the diffuser makes thepattern adjustments. The pattern isadjustable for horizontal left, horizontalright, or vertical throw.
Light Fixture Diffuser (LITE) –The LITE diffuser should be installedon a suspended ceiling light fixture.This type of diffuser is quite popularwith architects, because the number ofceiling penetrations can be reduced.The diffuser is available with anintegral sliding volume damper andwith or without pattern control vanes(some light fixtures already containpattern control vanes). Both thevolume damper and the patterncontrol vanes (if necessary) are
adjustable with a screwdriver from theface of the diffuser without removingthe light fixture doorframe. The patterncontrol vane allows for eitherhorizontal or vertical throw.
Induction Diffusers (INDT, INDB, INSR,INCB)—Induction diffuser discharges air in atight pattern along a ceiling. Thedischarged air then induces the roomair into the air stream to effectively mixthe streams. Induction diffusers aretypically used in exterior zones thathave unusually high heat loads ordrafts. They are designed to beinstalled in suspended ceilings andhave high induction horizontal airflow.The center down blow option providesa vertical air pattern for exterior wallsor glass. Induction diffusers haveadjustable blades for volume anddirection control.
INDT –This type of induction diffusercontains a supply air outlet only. It willproject air along a ceiling and providemixing of the primary and room airstreams.
INDT –This type of induction diffusercontains a standard supply air outletalong with down blow outlet. Thedown blow outlet will project a jet ofprimary air in a vertical direction whilethe standard outlet projects theinduction jet. The down blow jet isoften washed along an exterior glasswindow or aimed to combatsomething that is producing a draft inthe space.
INSR –This type of induction diffusercontains a supply air outlet along witha separate return air inlet integratedinto one device. This reduces thenumber of ceiling penetrationsnecessary.
INCB – This type of induction diffusercontains a standard supply air outlet, adown blow outlet, and a separatereturn air inlet integrated into onedevice.
Perforated Diffuser (PERF)The PERF diffusers are designed foruse with lay-in ceilings and provide themost economical option for airdiffusion. The pre-assembled diffuser ismade to lay in a 24" x 24"(0.610 m x 0.610 m) ceiling openingand is available with multiple roundinlet connection sizes. Outlets areavailable with disc or adjustabledeflector. The air is projected in acircular pattern from the diffuser.
