Date

Note

2_0 E26 16/06/2011 Improvements: Inserted section:pCOe electric schematic Improved section Electrical modbus connection

2.0.1 E28 15/07/2011 Improvements: Fixed sensor fault alarm B11 and B12, high pressure and low pressure sensor.

2.0.2 E28 01/08/2011 Improvements: Fixed various appearances and operations on VMF-E5.

2_1 E29 14/06/2011 Improvements: Inserted geothermal side modulating valve 3P. The valve will be indicated with Z in the unit configuration (special unit). If “compressor off with Zones off” is selected and there is a demand for dehumidification the system pump will activate. Specifics: Rewritten introduction section. Updated table of alarm

2_2 E30 16/09/2011 Improvements: Inserted in the set-up codes the letter "4" and "5". Inserted screen unit code double typing. Helps end of line tester. Inserted synchronising function at power-out: for 20s forces Geothermal Y2 output to 80%. Lets the Mut valve know that it is active. Improved screen H3 (total heat recovery=3 heat exchangers, DHW with valve, DHW with pump). Wizard: if STH is selected then the default enables also the control of dehumidification in the zones. Inserted screen D60 in/out modbus. Verifies the state of the modbus network. Heat recovery outlet water temperature sensor. Default enabled with heat recovery units. Inserted a K7 screen in the Wizard to ask if the sensor is NOT present, with visualisation of the temperature value. Summer total heat recovery. The system sensor is affected by the routing of the hot gas on the heat exchanger. Solution: insert a minimum run time for the DHW MQ6, default 10 minutes. Redesigned O15 screen, DHW status. As well as the value of the temperature insert also the outlet water. On recovery from power-out check if there is low pressure: below 2.0 bar. If there is open the electronic expansion valve until it returns to above the differential (2.5). Even so the function must not last more than 3 seconds. Improved screen manual override EEV. Sometimes the override to 0% did not work. Debug screen. Changed principal screen icon logic. Winter mode= sun, summer mode= snowflake. Carel recommended PID parameters with integrated EEV integrate and not external (Proportional = 5; Integral = 60; Derivative = 1") Now if Enter is pressed in the principal screen you end up in the ON/OFF screen.

2_2 E32 14/10/2011 Specifics: Inserted schematics of system side drycooler and drycooler with valve.

2.2.1 E33 26/10/2011 Improvements: Inserted parameter “time to pre-position EEV valve” for unipolar valves. Faster action digital input (thermal, high pressure). Update BIOS to 5.17, updated control function electronic valve on board µPC.

The latest software version is compatible with all previous.

2 Introduction The electronic controller fitted to the WRL (Water Refrigerant series L) unit contains the most important functions typical of Aermec water/water chillers. It has a whole series of functions designed to promote energy saving, such as:

- Stepped temperature control of the heat exchanger’s inlet/outlet water temperature - Proportional and integral control - Compressor rotation based on hours run - Operation of the primary and secondary pumps - Outdoor temperature based setpoint compensation (temperature sensor kit KSAE) - Seasonal change based on external temperature or calendar - Daily/weekly time-clock - Intelligent control of domestic hot water (DHW) production with desuperheater, bypass valve or double pump - Anti-legionella control through an immersion heater - Geothermal freecooling control - Solar heating control producing hot water for the system as well as DHW - Operation of a supplementary boiler only during critical periods of the year

The software developed and tested entirely by Aermec’s laboratory ensures the unit’s safety functions: - Monitors pump and compressor thermal cut-out - Anti-freeze function with the unit in standby mode - Pressure transducers in the evaporating and condensing sides provide low and high pressure control - Alarms (all displayed) can be automatic, semi-automatic or manual reset based on importance - All faults are recorded in the history log with the state of the unit at the time of alarm

Through an intuitive graphical interface the WRL unit shows the user the status of the various devices, sensors, etc., and allows a simple auto-assisted configuration (Wizard). A series of remote controlled options are additionally available:

- Remote control panel with main functions (accessory) - Volt free contacts for remote monitoring of the system or DHW - Double setpoint for both summer and winter preset in the menu - RS485 serial interface with ModBus protocol (AER485P1 accessory)

The WRL unit can control the air-conditioning of 3 environments (zones) with radiant floors - Each zone can have a dehumidifier, a circulating pump, a water temperature sensor and a mixing valve - Each zone can have up to two rooms except for Zone 1 which can have only one room - Each room will have a room sensor (STA -> th-tune) with an internal temperature sensor and a humidity sensor (optional)

WRL Schematic installation

3.5 Carel µPC board hardware characteristics

3.5.1 Carel µPC board power supply (terminal J1) The version used in the WRL unit is a Carel µPC board 230 Volt version.

It is recommended to separate the power supply of the Carel μPC board and display terminal from the rest of the electrical devices (contactors and other electro-mechanical components) within the electrical panel. The transformer provides double insulation between the device and the power supply network.

3.5.2 Sensors (various analogue input terminals)

All the low voltage connections (analogue and digital inputs of 24 Vac/Vdc, analogue outputs, serial bus connections, power supply) must have upgraded insulation or double insulation with respect to the network.

If the product is installed in an industrial location (application of the EN 61000-6-2 standard) the length of the connections must be less than 30 m. To avoid errors of measurement it is recommended not to exceed this length in any case.

3.5.3 Electronic expansion valve EEV connection (connector J11) The connector pins of the electronic expansion valve controlled by the Carel µPC board are connected as follows:

For WRL units up to size 140 the Carel model E2V electronic expansion valve is connected directly to the Carel µPC board through the appropriate connector (connector J11):

1 = green 2 = yellow 3 = brown 4 = white

In the case of unit models greater than size 140 the electronic expansion valve is indirectly controlled using the J8 output of the Carel µPC board to then control a support driver (see the Technical Assistance Service Manual).

3.5.1 Carel pGD1 display panel

The terminal can be mounted up to 50 m away using a telephone type cable, whilst using a twin screened cable, a TCONN6J000 and separate power supply, it can be mounted up to 500 m away. Note: in the case of a domestic installation the cable must always be screened. Cable type Distance Power supply Telephone 50 m From the pCO (150 mA) Screened cable AWG24

200 m From the pCO (150 mA)

15 pCOe Expansion board The Carel µPC board does not have sufficient input/outputs for all the functions.

The software therefore requires expansion input/outputs called pCOe (expansion boards) to meet the requirements of other functions (see section 3.4.1.1 Zone Control and 3.4.1.2 Drycooler Control). The pCOe boards can be powered by 24 Volt alternating or direct current. For the electrical connection see section 5.1 “Table of devices controlled on the ModBus network”.

16 Regulation

16.1 Chiller/Heat pump The application provides control of a water/water heat pump which can have up to two compressors in one refrigerant circuit. These can produce either hot or cold water for the system, based on the active seasonal mode and hot water for the DHW circuit. It controls up to two compressors in one refrigerant circuit which alternate using a rotation type FIFO (First In First Out). It controls the safety timers of the compressor and the relative pumps. For further information see the sections relevant in the Menu Service and Manufacturer. The unit can be supplied with an electronic expansion valve EEV, which below side WRL160 is directly controlled, whilst above this size requires the driver EVO. The guided installation (Menu Wizard) allows an easy configuration of the WRL once installed.

16.1.1 Control of the system side water The Carel µPC board controls the return water temperature of the system, or the outlet temperature (adjustable parameter). The control is divided between hot water production (winter), and cold water production (summer). The operational values are adjustable from the Menu Service sub-menu Chiller.

In the following diagrams the winter temperature control of the compressors (in the cases of 1 or 2 compressors); the summer operation is reversed and relative to the chilled water setpoint. Control can be either just proportional or proportional and integral.

In the winter operating mode of the primary circuit the supplementary heaters used (digital output NO6) are either heating elements inserted in the heat exchanger or a boiler. The temperature control of the chiller can be enabled even on the demand of a single zone. There are timers to ensure the correct functioning of the chiller. In the summer heating mode the outlet sensor of the primary circuit provides anti-freeze protection (see also the section dedicated to the anti-freeze function) of the unit’s heat exchanger.

16.1.2 Reversing control of the refrigerant circuit / water-side The WRL units can produce hot or cold water (heating or cooling mode), through a refrigerant reversing valve (heat pump unit); in this mode the flow of refrigerant is reversed in the heat exchangers (system and geothermal); alternatively installing a four way water-side valve for reversing the unit. 1. Reversing the refrigerant circuit


4.3.doc Pag. 82/135


Pag. 82/135 Pag. 82/135

2. Reversing water-side To reverse the cycle enter the Menu On/Off, turn off the unit and reverse the selection of the function in the same screen. The reversible unit is configurable in the Menu Service, in the sub-menu Conf.System.

The compressor(s) are always off during the change of mode.

16.1.3 Control of the system pump

The Carel µPC board has a digital output NO3 (terminal J12) to control a system pump. This is normally on when the unit status is ON. It is possible through screen P3 of the sub-menu Pump in the Menu Service to select pump ON with compressor demand. In this mode when the system thermostat demands the pump is enabled and the compressors are started after the normal timers.

If “ON COMP DEMAND” is selected it is recommended to select the control type as entering and to mount the inlet sensor B4 on the system buffer tank.

16.1.4 Control of geothermal pump The Carel µPC board has a digital output NO2 (terminal J12) to control the geothermal pump, as well as a 0-10 Volt output (Y2 terminal J5) to control a pump speed or throttling valve. The control of the pump can be: Type of control Geothermal heat exchanger as Evaporator Geothermal heat exchanger as Condenser Control compressors ON Output Y2 fixed, Pump ON Output Y2 variable, controls on outlet pressure and

differential Control on pressure Output Y2 fixed, Pump ON Output Y2 variable, controls on outlet pressure and

differential Control on geothermal side return water temperature

Set - differential = maximum speed Temperature above set = pump off

Set + differential = maximum speed Temperature below set = pump off

Control on geothermal side outlet water temperature

Set - differential = maximum speed Temperature above set = pump off

Set + differential = maximum speed Temperature below set = pump off

Before the compressor(s) start a minimum time from the start of the geothermal pump must pass, after the compressor(s) stop a time delay must pass to stop the geothermal pump. All the parameters are accessible in the sub-menu Pumps entering the Menu Service.

Control with condensing pressure Valv %= Speed of inverter or percentage open of the modulating valve HP= Value of the high pressure read from the transducer Max= Maximum inverter speed Min = Minimum inverter speed Set = Condensing setpoint Diff = Control differential

In total heat recovery mode (for DHW) the geothermal pump will always control with reference to the condensing pressure to avoid it dropping too.

16.1.5 Control of the alarms relating to the refrigerant circuit The Carel µPC board control the alarms of the compressor(s) exactly as: Alarm Cause Delay Reset Action Compressor thermal cut‐out Digital Input 2 and 9 No Manual Switch off compressor Pressostat high pressure Digital Input 4 No Manual Switch off compressor High pressure from HP Pressure B11 YES Manual Switch off compressor Low pressure 1 from LP Pressure B12 YES Automatic / Manual Switch off compressor Low pressure from LP lack of refrigerant Pressure B12 YES Manual Switch off compressor High temperature compressor discharge Temperature B9 YES Automatic Switch off compressor The low pressure alarm from the transducer is automatic reset for five attempts; the successive attempt becomes manual reset.

After restoration of power loss if the evaporating pressure is below 2.0 bar the electronic expansion valve EEV opens for 5 seconds to attempt to equalise pressures. This avoids the problem of resetting the serious alarm of low pressure.

All parameters regarding the safeties are found in the sub-menu Conf.Alarm in the Menu Factory.

16.1.6 Control of alarms relating to the hydraulic installation (system, geothermal, DHW) The Carel µPC board can control up to three pumps: one system pump, one geothermal pump and one dedicated to the DHW. Additionally two anti-freeze heating elements can be controlled which can also be used as supplementary heaters. The safeties connected to these pumps are: Alarm Cause Delay Reset Action Pump thermal cut‐out Digital Input 4 No Automatic Switch off all pumps Geothermal flow switch Digital Input 1 Start + run Automatic / manual Switch off geothermal pump System flow switch Digital Input 10 Start + run Automatic / manual Switch off system pump Geothermal anti‐freeze Temperature B1 or B2 No in cool / Yes in heat Selectable Switch off compressor System anti‐freeze Temperature B3 or B4 No in cool / Yes in heat Selectable Switch off compressor DHW tank immersion heater thermal cut‐out

Digital Input 6 No Automatic Switch off DHW immersion heater

System heater thermal cut‐out Digital Input 7 No Automatic Switch off boiler/electric heater External alarm to pCOe Digital Input 1 pcoe No Yes Switch off everything For the control of the system water flow switch either manual or automatic reset can be selected; in the automatic case five resets are allowed after which manual reset is required.

In the case of a reversible installation (with water-side reversing and external pump) the geothermal flow switch becomes the system flow switch and vice-versa.

All parameters regarding the safeties are found in the sub-menu Conf.Alarm in the Menu Factory.

16.1.8 Control to prevent refrigerant circuit high pressure The software installed in the Carel µPC board limits the unit’s capacity to prevent high pressure. The function to limit alarms, by limiting the capacity of the refrigerant circuit, ensures the continued operation of the unit. As can be seen in the following graph, if the high side pressure is higher than the Set value the software removes 50% of the unit capacity (in the case of a unit with two compressors one is witched off). If the pressure continues to increase the software removes even more capacity from the circuit until it reaches the high pressure alarm limit, turning off the system. If the condensing pressure drops below Set – Diff, the demand to limit capacity is disabled.

The capacity reducing function is not considered as an alarm but as an anomalous operation of the system.

16.1.9 Chiller setpoint There are various functions that will affect the unit’s principal setpoint

• Summer/Winter • Comfort/Economy • Temperature profiles based on exthernal air temperature • Low load control

Depending on the type of system configured in the Menu Wizard different setpoints are selected. As seen in this graph the operational setpoint will depend on the system type conditioned (cooling/heating) based on the exthernal air temperature.

16.1.10 Control of Chiller temperature profile

For energy saving purposes a setpoint compensation function based on outdoor air temperature can be enabled. Based on selected parameters the compensation can be selected as either positive or negative compensation.

As can be seen in the adjacent graph (summer example) the software creates a straight line with the parameters entered in the screen and depending on the offset there will be a smaller or greater compensation with respect to the initial setpoint. Legend:

The boiler can be activated based on the geothermal return water temperature or based on the outdoor air temperature. In any case there will always be a delay timer when enabling the boiler.

Through digital input ID7 (terminal J4 of the Carel µPC board) which serves as thermal cut-out for the heater/boiler, the alarms of the electric heater or boiler supporting the system can be controlled.

16.2 Control of DHW Through the Carel µPC board the software can control a DHW tank.

The type of control can be selected from the screens found in the sub-menu Conf.system in the Menu Service. The DHW tank can be controlled as:

• Desuperheater • Total heat recovery with DHW priority • Priority with mixing valve • Priority with DHW pump in parallel to the system pump

The demand for DHW production comes from a thermostat request and functions based on setpoint, DHW temperature and range, with reference to the sensor B3 (terminal J3 of the Carel µPC board). The demand for compressor(s) is based on the system outlet temperature or of the total heat recovery outlet temperature.

DHW only operation can be forced from the screen in the sub-menu On/Off in the Menu User, or through the digital input ID4 terminal J4 adding and additional pCOe expansion board.

The active setpoint does not change with the change of season.

The control of the DHW valve, output Y1 (terminal J5 of the Carel µPC board), follows the same logic of output NO4 (terminal J13) but with a modulating proportional control based on the parameters found in the sub-menu DHW in the Menu Service.

16.2.1 Control of the desuperheater in cooling only mode The desuperheater is a heat exchanger installed in the compressor(s) discharge piping and partially recovers the discharge heat directly after the compression phase during cooling mode operation of the unit (remember that the complete condensing phase of the compressed refrigerant occurs in the condenser). Therefore heat recovery from the desuperheater is linked to the production of chilled water for the system by a demand for the unit to run. The installer can decide whether to use the DHW pump to obtain the benefit of the heat of compression through the desuperheater. The DHW pump NO4 (terminal J13) is on only if the compressor(s) are operating and the unit is in summer mode. The DHW pump NO4 (terminal J13) can operate either through the demand from the sensor B3 (SSAN DHW sensor), or acting on the parameter P18 in the sub-menu Pumps of the Menu Service, “activation DHW pump in summer” selecting the option of when compressors run.

16.2.2 Control of the total heat recovery The WRL unit with total heat recovery are made up of three heat exchangers: system, geothermal and DHW, generally of equal sizes. Whilst for the cooling only unit with desuperheater the partial heat recovery function is linked to the demand of the system thermostat. For the heat pump unit with total heat recovery the controls operate as follows:

Through the refrigerant reversing valve the system and geothermal heat exchangers can exchange roles of evaporator and condenser based on the requested functioning mode. The DHW heat exchanger always remains a condenser. The DHW demand is always priority so the unit always satisfies the DHW based on the setpoint and temperature read at the DHW tank sensor (SSAN), then satisfies the system demand. In heating function the system pump remains switched off when there is a DHW demand and the geothermal heat exchanger acts as the evaporator. In cooling function if there is a simultaneous demand for DHW and for system cold water the geothermal pump is switched off and the system heat exchanger acts as the evaporator. Once the DHW demand is satisfied the unit will operate in cooling or in heating mode based on the operating mode configuration. During changes of functions the compressor and reversing cycle timers are always respected.

From software version 1.9 it is possible to use a sensor in the heat recovery outlet (selectable) to control the demand for compressor(s) operation. The setpoint and differential are found in the parameter Q30 in the sub-menu DHW in the Menu Service. The enabling and control of the DHW remains unchanged.

16.2.3 Control of the DHW (priority) with 3 way device valve The device valve is a water-side valve located downstream of the unit’s system heat exchanger. The device valve diverts the water either towards the system/system buffer tank or towards the DHW. In the case of DHW demand: - compressor(s) on are switched off, respecting compressor timers - system/sanitary pump is switched off (output NO3,remind, it is used the same pump for system and sanitary water because is presente the three way device valve from system to sanitary) - the three way device valve is activated (output NO4) - wait for an adjustable delay timer (parameter Q12 in the sub-menu DHW in the Menu Service) that allows the valve to position towards the DHW tank - system/sanitary pump is switched on (output NO3,remind, it is used the same pump for system and sanitary water because is presente the three way device valve from system to sanitary) - geothermal pump is switched on (output NO2) - the reversing valve is forced into heat pump mode (if it is not already) - compressor(s) restart based on the sensor entered in parameter Mq3 in the sub-menu DHW of the Menu Factory - once the DHW demand is satisfied the above operations are repeated and position the device valve towards the system buffer tank

16.2.4 Control of the DHW (priority) with DHW pump The DHW pump is a pump located downstream of the unit’s system heat exchanger in parallel with the system/system buffer pump. The two pumps operate alternately to each other. In the case of DHW demand: - compressor(s) on are switched off, respecting compressor timers - system pump is switched off (output NO3), ignoring the stop delay timer - geothermal pump remains on (output NO2) - DHW pump is switched on (output NO4) - the reversing valve is forced into heat pump mode (if it is not already) - compressor(s) restart based on the sensor entered in parameter Mq3 in the sub-menu DHW of the Menu Factory - once the DHW demand is satisfied the above operations are repeated and the system pump is switched on in case of demand

16.2.5 Control of the DHW pump of inverter type or modulating valve The Carel µPC board has as standard a digital output NO4 to control a pump ON/OFF and an output Y1 to control variable pump speed or a modulating valve (throttling) on to the sanitary side. In DHW mode when the DHW pump starts low pressure in the DHW heat exchanger could occur, which is acting as a “condenser”, causing a low condensing pressure. To avoid this it is advantageous to have a DHW pump of inverter type or a modulating valve to maintain an adequate condensing pressure. The setpoint and differential values and the values for minimum and maximum pump speed/valve opening are contained in parameter Q21 found in the sub-menu DHW of the Menu Service.

Inv(%)= percentage speed of the pump inverter or percentage opening of the modulating valve Max= Maximum pump speed/valve opening Min = Minimum pump speed/valve opening Setpoint= Minimum pressure value below which the pump inverter runs at minimum speed (eventually stops)/modulating valve starts to close Diff = Differential

16.2.6 Control of the DHW pump ON/OFF

To maintain condensing control during DHW functioning an alternative to a pump inverter an ON/OFF pump control function can be selected where the operation is based on not just on the thermostatic demand with reference to the water temperature of sensor B3, but also taking into account the values inserted in the parameter Q21 found in the sub-menu DHW of the Menu Service.

In this case the following function occurs: • DHW demand for hot water • Reversing cycle to winter mode or total heat recovery • Start of the DHW pump and eventually geothermal and system pumps • Delayed start of the compressor(s) • Stop the DHW pump based on low condensing pressure • Start the DHW pump to raise condensing pressure • Starting and stopping the pump to bring the condensing pressure to an acceptable value

Clearly during these phases the safeties of the compressor always remain active.

The choice to make the DHW pump operate immediately after a demand for DHW or only after starting compressor(s) is selectable in parameters P18 found in the sub-menu Pumps of the Menu Service.

For units fitted with the electronic expansion valve (digit X in the configurator) the operation of the DHW pump with condensing pressure control must not be selected, because the LOP, internal algorithm controlling the electronic expansion valve, will ensure the condensing pressure is maintained within normal operating values.

16.2.7 Control of the condenser pump during heat recovery When the heat recovery heat exchanger operates the other heat exchanger used as the condenser in the refrigerant circuit is not used, then its may be or the system heat exchanger during heat pump mode operation or the geothermal heat exchanger during cooling mode operation. Vice-versa, when the heat exchanger used as condenser is operating the heat recovery heat exchanger is not used. In particular during the last situation described, taking into account that the heat recovery heat exchanger is not operating since the DHW temperature is satisfied; if during operation the evaporating pressure should drop below 7.0 bar (0°C) the pump is started relating to the heat exchanger that is off and will stop at 7.5 bar (1.6°C). This operation permits the heat of the hot water in the heat exchanger not operating to be used to raise the condensing pressure and as a consequence the evaporating pressure. The forced starting of the pump for the heat exchanger not operating will not be activated if the inlet water temperature is too low.

Parameter P34 found in the sub-menu Pumps of the Menu Service. The forcing of the pump for the heat exchanger not operating operates in this mode: NO: function not enabled WINTER ONLY: to avoid sending hot water to the system during summer operation ALWAYS: whenever heat recovery is operating this function is always active

16.2.8 Control of the anti-legionella treatment From the DHW menu found in the Menu User, it is possible to activate (if a supplementary system is enabled in the Menu Wizard screens K18 and K21) a weekly algorithm for anti-legionella treatment. Through the output of the board NO8 a supplementary system can be activated (boiler or immersion heater) to heat the DHW so that raising the temperature avoids problems associated with the proliferation of the Legionella bacteria. This function is only available if the immersion heater within the DHW tank is enabled (screens K18 and K21 of the Menu Wizard). This function is active even with the unit off.

Entering in parameter Q15 of the sub-menu DHW of the Menu Service allows: - insertion of the start time of the anti-legionella function - the days of the week it is activated - decide whether to disable

To stop the treatment the DHW temperature B3 must remain above the setpoint for a minimum time of 5 minutes (adjustable). If the treatment does not stop within the maximum time of 120 minutes (adjustable) an alarm is generated and the anti-legionella function is interrupted

It is possible to force the anti-legionella function entering in parameter M27 of the sub-menu Manual of the Menu Service.

16.2.9 Control of the DHW time-clock The operation can be enabled or disabled by the DHW daily time-clock. If in the menu DHW contained in the Menu User the DHW time-clock is enabled (screen D6) up to 4 daily programmes for the 7 days of the week can be programmed.

16.3 Control of zones The Carel µPC board, supported by Carel pCOe expansion boards with addresses 11 and 12, can control the conditioning of up to 3 spaces (zones). Each zone can have up to two rooms, except for Zone 1 which can have only one. Each room is defined by a room sensor (STA) with an internal temperature sensor or temperature and humidifier sensor (STH). The temperature control of the chiller is enabled on the demand of a single zone. There are timers to ensure the operation of the chiller. While Zone 1 is controlled directly from the Carel µPC board, Zones 2 and 3 are controlled by a pCOe expansion board for each zone. Each zone can control a modulating valve and a recirculating pump. In detail, every zone can control: - a 0-10 V output for a mixing valve - two digital outputs for the pump control or valve for each room - a digital output for the principal pump control of the zone - a digital output to control the dehumidifier - an input for the mixed circuit outlet sensor - a digital input for pump thermal cut-out Each room can be switched on by the room sensor or the main controls, and has a time-clock (see section relating to time-clock), and two dedicated setpoint (adjustable even from the room sensor) for heating and for cooling. The control of spaces is divided between winter control and summer control. In case of only one zone then one room, request heat/cool, the Carel µPC manage directly the pump of zone (output NO12) and the mixing valve (output Y3). In case of 2 or 3 zones then with pCOe expansion board, if there is/are a room/s heat/cool demand the room’s valve will be closed (output NO2 or NO3), the circulating pump (output NO1) and the mixing valve (output Y1) are switched on.

16.3.1 Control of room setpoint Based on the functional status of the unit (heat/cool) the software will use one of the two setpoints present in the screens found in the sub-menu Zones of the Menu Service. If instead the time-clock of that room is used the setpoints configured in the time-clock selected in the Zones of the Menu User are used. If the time-clock is selected but it does not require the room to be switched on then the two setpoints will be used as default.

It is possible to change the active setpoint from the screens found in the menu Zones of the Menu User or directly from the room sensor, creating a “temporary” setpoint. For each new time-clock programme activated, or for a change of mode (heat/cool) the “temporary” setpoint that was previously inserted will be overwritten

The temperature control using the active or temporary setpoint acts on the room valve to try to maintain the space temperature within the operating range using the differential control

16.3.2 Control of zone setpoint Each zone controls one pump and one mixing valve 0-10 Volt. If at least one room has a demand (from the STA/H sensor) of that zone, the pump is started and the valve begins to control.

If a STA/H is not configured as present the system works with reference to the temperature seen by the sensor B1 or through the digital input “ON/OFF Zone” of the pCOe expansion board (see section 3.4.1.1 with relevant wiring schematic on page 13). The valve can be controlled by simple proportional control or proportional and integral control.

3 different types of setpoint can be selected: 1. A fixed setpoint for heating and a fixed setpoint for cooling 2. Setpoint based on a temperature profile 3. Setpoint based on dewpoint temperature (only in summer mode).

The temperature profile depends on the outdoor temperature and the parameters configured as in the example of the screen adjacent (Z39). Like this temperature profile others can be found in the screens found in the sub-menu Zones of the Menu Service

Winter:

SpV= setpoint valve mix Text = external air temperature MaxS= maximum setpoint limit valve mix MinS= minimum setpoint limit valve mix AvrS= average setpoint valve mix MaxText= maximum external temperature limit MinText= minimum external temperature limit AvrText= average setpoint external

Summer:

For the three zones six temperature profiles are available: three summer and three winter. All the parameters are found in the sub-menu Zones of the Menu Service or in the menu Zones of the Menu User.

It is possible to manually force the percentage opening of the zone valve entering the parameter M6 of the sub-menu Manual of the Menu Service.

16.3.3 Control of dewpoint setpoint With radiant cooling of the floor there is always the risk of the formation of humidity and associated problems. The humidity and temperature sensors are found within the room sensor STAH (th-tune). With these sensors the dewpoint is calculated. The software takes the greater of the two dewpoints obtained from the STAH sensors present in the two rooms of the zone, and adds on safety offset to this value adjustable from screens Z45, Z57 and Z69 found in the sub-menu Zones of the Menu Service. This new value is used as the water setpoint for the mixing valve.

16.3.4 Control of the room time-clock To each room one of the 5 time-clock programmes can be associated configured in the menu Time-clocks of the Menu User. This allows several rooms to have the same time-clock programme. Each programme has 8 possibilities: 7 days of the week plus one “holiday”. The latter is only active if the holiday mode is requested in the calendar function. In this way it is possible to programme the time-clocks for days when absent or for days that a special temperature control is desired. Each day is subdivided into 4 time-clocks (a,b,c,d). Each time-clock has a start time and finish time. Additionally, each time-clock has two setpoints: one for winter control and one for summer control. Outside of these time-clocks the room is considered Off (temperature control switched off).

The programmes of the time-clock are not visible on the STA/STAH room sensor.

16.3.5 Control of compressors off with zones off To save energy for the operation of the system pump or the operation of the compressors in small installations, the compressors can be switched off when there are no STA/H sensors that demand hot/cold water or dehumidification, through the parameters E4 found in the sub-menu Chiller of the Menu Service. Obviously there will be a delay in switching off the compressors when the zones switch off and a delay starting the compressors when the zones start. This is because the thermal inertia of the water controlled by the chiller/heat pump is different to the thermal inertia of the air controlled by the STA/H sensors.

16.3.6 Control of the dehumidification For better comfort control of the space the temperature and the humidity can be controlled. Each zone has a digital output to control a dehumidifier. The humidity sensors are within the STAH (th-tune) room sensors. If one of the two humidity sensors STAH in the rooms of a zone see a humidity value below the setpoint defined in parameter r48 found in the menu Zones of the Menu User (making reference also to parameter Z78 found in the sub-menu Zones of the Menu Service), the operation of the dehumidifier is enabled.

16.3.7 Control of zone safeties The system controls for each zone the high and low temperature alarms relating to the mixing sensor. Additionally based on the temperature read on the STA/H room sensor it can control an anti-freeze function. In the case the ant-freeze function is active the room valve is forced open, the pump zone is started and the system is forced On y anti-freeze.

This safety operates even with the room switched off. Alarm Cause Delay Reset Action High temperature mixed circuit 1,2,3

16.4 Control solar heating KIT Available as an option for all models. The solar heating kit is made up of a Carel pCO Compact board that can operate stand alone (using its own sensor) or connected via ModBus to the Carel µPC board (adding the Carel pCO Compact board with address 16) and using the sensors from the WRL unit. The solar heating kit can work in substitution to the WRL unit or supplementary to.

The parameter B3 for enabling the solar module is found in the sub-menu Accessory of the Menu Service; all the other parameters for the control of the solar module are found in the sub-menu Solar of the Menu Service. To use the solar heating there must be a temperature differential between the solar panels sensor S3 and the DHW temperature (read from sensor S2) or the system temperature (read from sensor S1). If the temperature of the collector S3 – S2 or S1> dT solar = solar enabled for DHW or system If the temperature of the collector S3 – S2 or S1 < dT minimum solar = solar disabled for DHW or system The priority is always for the DHW, then the system heating, and eventually rejecting excessive heat to the geothermal.

16.5 Control of freecooling KIT Available as an option for models below size WRL180. As seen in the hydraulic system “Cool only with freecooling” on page 24, the Carel µPC board through a 3 way water valve V3V controlled from output NO11, can use the low water temperature of the ground in summer mode.

The parameter B3 to enable the freecooling and the parameter B21 for the control of the freecooling are found in the sub-menu Accessory of the Menu Service. At the demand of the thermostat the geothermal pump starts (output NO2) and the freecooling valve opens (output NO11). After an adjustable time the software controls the temperature difference between the system return temperature (B4 sensor) and the geothermal return temperature (sensor B2). - If there is a cooling demand and the difference in temperatures B4-B2 > dT entered in the parameter the freecooling valve (output NO11) remains on. - If there is a cooling demand and the difference in temperatures B4-B2 <dT –hysteresis entered in the parameter the freecooling valve (output NO11) switches off and the compressor(s) start. - If there is no cooling demand the freecooling valve (output NO11) switches off.

The freecooling valve and the compressor(s) are never on together. The system and geothermal pumps remain on with the unit switched on. Example 1: Operation with freecooling only

Example 2: Operation with compressor(s) only

16.6 Control of the electronic expansion valve EEV The WRL unit supports two types of drivers for electronic expansion valves. The units below size WRL180 use the on board driver and so the electronic expansion valve is directly connected to the Carel µPC board at output J11. The units above size WRL180 use an external driver connected to the pLAN network at output J8 of the Carel µPC board, code EVD0000E40, and with address pLAN 5. The driver operates a two direction stepper motor to control the electronic expansion valve. The electronic expansion valve controls the refrigerant superheat and to optimise the refrigerant circuit output. The low pressure sensor is always a single one and depending on the case is connected to the Carel µPC boards or the driver EVO. Model WRL Model Electronic Valve WRL H 025 E2V18 WRL H 030… 070 E2V24 WRL H 100 E2V30 WRL H 140…200 E3V45 WRL H 300…400 E3V55 WRL H 500…550 E3V65 WRL H 600..650 E3V85

16.6.1 Control of unit mounted EEV For small refrigerant capacities the dedicated output from the Carel µPC board can be used to control the electronic expansion valve. To calculate the superheat the sensors B10 and B12 are used: suction temperature and evaporating pressure. The control is completely identical to the external driver. The type of valve connected shall only be the EXV Carel bi-flow.


4.3.doc Pag. 97/135


Pag. 97/135 Pag. 97/135

16.6.2 Control of external EEV In the medium large refrigerant capacities it is necessary to connect the Carel EVD****50 drive on the pLAN network to the Carel µPC board to control the electronic expansion valve. The address of the driver will be 5; no digital inputs from the Carel µPC board are needed.

16.6.3 EEV PID parameters The control of the superheat comes through a PID type characterised by three contributors: proportional, integral and derivative. The proportional action opens or closes the valve proportionally in variation to the superheat. The greater the value of the proportional gain the greater the speed of response of the valve. If the superheat does not vary significantly the valve will remain almost closed and the setpoint will not be guaranteed. The integral action is linked to time and makes the valve move in proportion that the superheat is away from setpoint. The greater the value the greater the integral action; additionally the smaller the integral time value the greater will be the action. The integral time effectively represents the intensity of the reaction of the valve particularly when the superheat is far from setpoint. The derivative action is linked to the speed of variation of superheat, or effectively the rate of change of superheat. It counteracts the quick variations anticipating a corrective response and the greater the derivative time value the greater the action.

All the parameter linked to the control of the electronic expansion valve can be found in the sub-menu Driver EEV in the Menu Factory.

16.6.4 EEV alarms The driver is provided with the following protective functions: Code Alarm Cause Param Delay Action AL89 Sensor alarm Temperature B10 /pressure B12 or driver sensor ‐ 30s EEV forced closure AL90 Low superheat (LowSH) ‐‐‐ ER12 ER18 Circuit off AL91 Low evaporator temperature (LOP) Pressure ER12 ER18 Circuit off AL92 High evaporator temperature (MOP) Pressure ER12 ER18 Circuit off AL93 High condensing temperature ‐‐‐ ‐‐‐ ‐‐‐ AL94 EEProm alarm Configuration error ‐‐‐ ‐‐‐ Call Service AL95 Valve motor error Valve disconnected or configuration error ‐‐‐ 10s Circuit off AL96 Driver Offline Driver disconnected ‐‐‐ 60s Circuit off AL97 Low suction temperature Temperature B10 – suction sensor ER21 ER21 Circuit off AL98 Low battery External EVD battery ‐‐‐ ‐‐‐

All alarms are automatic reset.

16.7 Unit On/Off In the WRL units the On/Off of the unit is affected by several factors, which can be:

• from the display on the unit • from remote control, digital input ID8 • from time-clock • from supervisory BMS system • from forced evaporator anti-freeze

From the first selection row of the screen u3 in the menu On/Off of the Menu User it is possible to change the state of the unit (see section “Menu On/Off “): Off: the whole system is in off mode On: the system is enabled to operate based on the setpoints entered Economy: the system controls with energy saving setpoints Auto: the system operates according to the time-clock programmes

For the unit to be in the On state all factors which can influence the On/Off must be enabled to the On state. The only exception is the forced anti-freeze which forces the state of the unit to On.


4.3.doc Pag. 98/135


Pag. 98/135 Pag. 98/135

16.8 Change of season Still on screen u3 of the menu On/Off of the Menu User the functioning mode of the unit can be changed. See section “Menu On/Off “ Generally it is possible to change the mode of the unit only when switched off. For “Summer” it means chilled water production. DHW will still be priority. For “Winter” it means hot water production. DHW will still be priority. For “Only DHW” it means the unit ignores the system temperature and tries to satisfy the DHW demand.

If the change of season with external temperature sensor is selected in this screen u27 of the menu On/Off of the Menu User it is possible to select the limits of change of function of summer to winter. If the temperature is within the two limits the unit will remain in the mode it was functioning before

Clearly the selection of operating mode is activated based on the configuration of the unit and based on the accessories installed. In parameter B22 found in the sub-menu Accessories of the Menu Service the change of season can be enabled from a digital input of the pCOe board accessory, or in parameter B24 still in the same sub-menu Accessories, the operation of the unit can be enabled based on demand from the supervisor system VMF. The system VMF will have priority on all other selections.

16.9 Control of low load and force off Through parameters E18 and E21 found in the sub-menu Chiller of the Menu Service the system for situations of low thermal load can be controlled.

If the temperature of the evaporator outlet water side (cooling mode, geothermal in heat pump mode) drops below the minimum limit the compressor(s) are stopped ignoring the safety timers.

The control of low load foresees that the unit reaches the level of forced stopping due to low outlet temperature in cooling mode. The compressor(s) restart at a higher temperature level (in cooling mode) than that requested by the thermostat so that the compressor(s) operate for at least the minimum run time. In the case of two compressors the second compressor can start when the first has exceeded the minimum run time.

16.10 Output control alarm To eliminate the problem of inverted sensors between the water inlet and outlet (as a function of the operating mode determined), the software checks the difference in water temperature between inlet and outlet of the heat exchanger of interest.

Through parameter A54 found in the sub-menu Conf. Alarm in the Menu Factory, the functions can be enabled, the delay timer, the temperature differential required for the operation in cooling and heat pump mode can be selected. The control results when:

• the heat exchanger pump (system or geothermal) is on • the compressor is on after a adjustable time • following the preceding timings there must be a minimum temperature difference

between water inlet and outlet (as a function of the operating mode determined)

If the temperature difference (dT) between water inlet and outlet (as a function of the operating mode determined) is less than the selected value the output alarm is generated.

16.11 Auxiliary Sensor B5 Through the software an auxiliary sensor B5 can be used for multiple functions:

Through parameter B33 found in the sub-menu Accessories of the Menu Service the auxiliary sensor can be disabled or enabled selecting what it controls:

• Total heat recovery outlet temperature. Used in the unit with total heat recovery • System common temperature. Used when there is a system buffer tank • Setpoint compensation (4-20 mA) • Setpoint from analogue input (for example potentiometer, control from PLC, etc.)

Still in the sub-menu Accessories in the screen B36 the maximum and minimum limits of the deviation from the system principal setpoint can be fixed for both heating and cooling (compensation)

Example of system setpoint compensation through active analogue input 4-20 mA B5= analogue input B5 Set= principal setpoint used by the unit Max= maximum offset Min = minimum offset

In the case the B5 auxiliary sensor is enabled selecting a control mode in parameter B33 found in the sub-menu Accessories the value read by the auxiliary sensor can be seen in parameter D03 found in the sub-menu In/Out assistance of the Menu Service.

16.12 Control of the drycooler system Using the outputs of the pCOe expansion board accessory with address 10, the software is capable of controlling a drycooler system (air heat exchanger with fans) to produce chilled water which will be used on the geothermal side (heat exchanger) in place of or to assist (for particular cases) the geothermal probes. If normally the air heat exchanger drycooler is used in place of the geothermal probes (or for particular cases as supplementary), then there are certain installations where a continued supply of chilled water is needed, where the drycooler, assuming the outdoor climatic conditions are optimal, will offer this energy directly to the system; in these cases the drycooler becomes effectively a freecooling system on the air-side of the system. See sections 6.8, 6.9 and 6.10 of the text.

In the sub-menu Accessories of the Menu Service, entering screen B27, the operation of the drycooler system can be enabled. The fans/valve controlled from output Y1 (0-10 Volt) control based on the setpoint and differential defined in the screen B27 in the sub-menu Accessories of the Menu Service based on: - Return geothermal temperature - Supply geothermal temperature - Drycooler temperature (sensor B1 of the pCOe board) - System return temperature

For the drycooler to operate the external temperature must be less than the temperature controlled plus a temperature difference (dT) defined in the screen B30 found in the sub-menu Accessories. If the operation of the geothermal or freecooling pump is not requested then the Drycooler will remain switched off. If the system return Temperature is selected the Drycooler will operate as external freecooling. Hence it will start if the unit is in summer mode and the unit is on with demand for compressor(s) operation.

17 System alarms

17.1 Alarm history The last 100 alarms of the WRL unit or related devices can be seen in the alarm history pressing the key. For each alarm event it is possible to have:

Principal screen - date and time of the event - nature of the alarm - geothermal inlet/outlet temperature - system inlet/outlet temperature - DHW temperature - refrigerant circuit low pressure

Successive screen to the preceding (visible pressing the Enter key) - date and time of the event - nature of the alarm - status of the unit - status of the compressor(s) - status of the pumps - refrigerant circuit high pressure

When the last position of the alarm history is reached the software will overwrite the first (which was the oldest) with the most recent event.

17.2 Alarm list Rearm mode: Auto = Automatic, the alarm disappears when the event that has triggered the alarm has ended. Manual = Manual, manual reset of the event is required in order to resume standard operation when the event that has triggered the alarm has ended. Semi = Semi-automatic, rearming is automatic but it becomes manual when alarm is triggered more than three times in one hour period. Alarm Code

18 BMS System

18.1 Addresses dedicated to the control of the VMF E5 The software installed in the WRL unit is compatible with the VMF platform. In particular it can be used as a simple Chiller or Heat pump.

In this case the control of the DHW and of the internal zones of the WRL unit will remain stand alone.

The WRL unit must be addressed to 200 as ModBus. The VMF-E5 panel can start/stop the WRL, change its setpoint and have information about its operation. There can be several different reasons for the lack of hot/cold water production from the WRL unit following a request from the VMF-E5: - pump/compressor timers - internal time-clock - internal alarms of the WRL unit - non-optimal output conditions for the WRL unit - inhibition of system water production in favour of the DHW Theoretically the client could have the two WRL + VMF-ACS systems of DHW production. In this case the system will operate in this way: The DHW sensor of the WRL unit and the DHW sensor of the VMF-ACS system will be placed in the same DHW tank. If hot water is needed for the DHW the WRL unit will give priority to produce DHW. When finished it will produce hot/cold water for the VMF system. In 99% of cases when the DHW demand is satisfied by the WRL unit even the demand from the VMF system will be satisfied as they have similar setpoints and the sensors are located in the same tank. If the tank cannot be brought to temperature in 3 hours the VMF system will give an alarm signal. Type Addr.

mc43_0.s19 13-06-2011 Version 4.3.0 - Control WRL cooling only (water/water unit). Read condenser input sensor in place of condenser coil sensor and read condenser outlet sensor in place of outdoor air sensor. - The outdoor air temperature (optional Kit KSAE) is read from sensor 25° 10 kOhm connected in place of the low pressure transducer (ratiometric).

22 Introduction The Moducontrol electronics was introduced in 2006, besides to meet the need for a controller for the new range of air-water chillers series ANL with refrigerant R410a, but also to have a new electronic controller designed and produced by Aermec. Since then this controller has been used on two compressor units and the ANZ (high performance heat pump unit with R407c, sometimes accompanied with accessories like supplementary electric heating and soft start) that were call ANR Then the control logic for inverter units was added, known as ANLI and the condensing version ANL-C. The last update of this electronics is for the water-water series WRL cooling only.

Important: as the control logic of the Moducontrol board is practically the same for the ANL/ANR series, this document only shows the complete hardware architecture (analogue and digital inputs and outputs) and the main menus (Menu readings and Menu set user), where specific to the parameters relating to the control of the units WRL series. Only relevant parts of other menus will be shown.

For the complete document of the Moducontrol electronic controller refer to the specific control manual.
