V - Ap pli ca tion
Unitary Energy Recovery Ventilator (UERV) are used with 15 to 30
ton rooftop units equipped with a balancing damper assembly. These
wheels conserve energy by mixing warmer air with cooler air in the
following manner:
Recovery Wheel Mode
The Recovery Wheel mode is accomplished by two blowers providing
continuous exhaust of stale indoor air and replacement by equal
amount of outdoor air. Energy recovery is achieved by slowly
rotating the energy recovery wheel within the cassette frame work.
In winter, the UERV adsorbs heat and moisture from the exhaust air
stream during one half of a complete rotation and gives them back
to the cold,drier intake air supply during the other half rotation.
In summer, the process is automatically reversed. Heat and moisture
are absorbed from incoming fresh air supply and transferred to the
exhaust air stream. This process allows outdoor air ventilation
rates to be
increased by factors of three or more without additional energy
penalty or increase in size of heating or air conditioning
systems.

VIII - Operation
How It Works
The unit contains an Energy Recovery Wheel (ERW) that is a new
concept in rotary air-to-air heat exchanger. Designed as a packaged
unit for ease of installation and maintenance, only matching up to
rooftop unit with an internal balancing damper and connection of
electrical power is required to make the system operational. The
concept consists of a unique rotary energy recovery wheel that
rotates in and out of fresh air streams within a heavy duty,
permanently installed blower cabinet that provides ready access to
all internal components. The media is polymeric material that is
coated and permanently bonded with a dry desiccant for total
enthalpy recovery. The wheel is belt driven by PSC motor and drive
belt.
When slowly rotating through counter flowing exhaust and fresh air
streams the UERV adsorbs sensible heat and latent heat from the
warmer air stream and transfer this total energy to the cooler air
stream during the second half of its rotating cycle. Rotating at 60
revolutions per minute, the wheel provides constant flow of energy
from warmer to cooler air stream. The large energy transfer surface
and laminar flow through the wheel causes this constant flow of
recovered energy to represent up to 85% of the difference in total
energy contained within the two air streams.
Sensible and latent heat are the two components of total heat.
Sensible heat is energy contained in dry air and latent heat is the
energy contained within the moisture of the air. The latent heat
load from the outdoor fresh air on an air conditioning system can
often be two to three times that of the sensible heat load and in
the winter it is a significant part of a humidification heat
load.
During both the summer and winter, the UERV transfers moisture
entirely in the vapor phase. This eliminates wet surfaces that
retain dust and promote fungal growth as well as the need for a
condensate pan and drain to carry water.
Because it is constantly rotating when in the air stream, the UERV
is always being cleared by air, first in one direction then the
other. Because it is always dry, dust or other particles impinging
on the surface during one half cycle, are readily removed during
the next half cycle.
Additional Information for Options are provided in Options
Manual.
Re cov ery Mode
On a thermostat call for blower operation in heating, cooling or
continuous blower, the ERW will rotate between fresh air and
exhaust air streams. Both the fresh air and exhaust air blowers
will also be operating to overcome the air resistance of the
UERV.
Free Cool ing Mode (op tional)
The Start, Stop, Jog kit is an optional control board with
temperature and/or enthalpy sensor(s) that stops the enthalpy wheel
from spinning (and transferring heat) when temperature conditions
are conducive for free cooling. The board will spin the wheel
intermittently in 10 min off 1 min on intervals to keep dust from
building up on the surface.
All units shipped with the Start, Stop, Jog option installed have
the temperature and enthalpy sensors installed, and the jumper (J9)
set to T(emp). A qualified tech can adjust the setting to
E(nthalpy) only or Temp and Enthalpy by adjusting the jumper
(J9).
The factory set points to allow for free cooling during ventilation
are 40oF-70oF, but they can be field adjusted to narrow the band by
adjusting two potentiometers while measuring VDC between the Com
& High or Com & Low terminals (0 VDC = 40 degrees, low set
point, 5 VDC = 70 degrees, high set point).
IX - Sys tem Check
1. Disconnect main power.
2. Turn thermostat to "Cont" for blower operation.
3. Restore power to unit. Observe UERV wheel rotation and both
fresh air and exhaust air blowers will operating.
Note: If Low ambient kit is used the jumper between TB37-5 &
TB37-6 should be removed. Also if system check out is being
conducted at low ambient temperatures, technician should be aware
that this kit can cause system not to operate.
4. Verify that the UERV (3) three phase blower motors are phased
sequentially ensuring correct rotation and operation.
a) Disconnect power.
b) Reverse any two field power leads to the UERV.
c) Reapply power.
A - Re turn Damper Set tings
Manually adjust position of dampers. This is accomplished by
loosing and tightening set screw on positioning rod.
B - Blower Speed Ad just ment
Blower speed selection is accomplished by changing the sheave
setting on both fresh air and exhaust air blowers. Both blowers are
factory set at "closed" for maximum airflow. To determine air flow
setting, external static pressure readings will need to be read
across the UERV. See Figure 15 for location to take pressure
readings.
PAGE 6
& VR062A15M/H/25M/H (STATIONARY)
1. Remove plastic plugs in door panels (4 total).
2. With a manometer measure the pressure drop [Inches Of water
column] across the wheel on the supply airflow side of the unit
(Top). The unit’s CFM is determined by referring to Table #1. If
the Cfm value is not per design adjust the motor sheave until the
desired CFM is reached.
3. To adjust the exhaust airflow check the pressure on the exhaust
side of the unit (Bottom), then remove the door panel to access the
return air dampers installed inside the RTUs return air section.
Adjustment of the damper is made by loosening the wingnut,
adjusting the damper blades and then tightening the wingnut before
closing the panel and measuring again.
4. Once desired the CFM is reached replace the plastic plugs in the
access holes in the doors.
X - Main te nance
Motor Maintenance All motors use prelubricated sealed bearings; no
further lubrication is necessary.
Mechanical Inspection Make visual inspection of dampers, linkage
assemblies and UERV rotating bearings during routine maintenance.
Filters should be checked periodically and cleaned when necessary.
Filter is located in fresh air hoods. DO NOT replace permanent
filters with throwaway type filters.
Belt Alignment Proper alignment is essential to maintain long
V-Belt life. Belt alignment should be checked every time belt
maintenance is performed, each time the belt is replaced, and
whenever sheaves are removed or installed.
Belt Installation Always move the drive unit forward so the belt
can be easily slipped into the groove without forcing them. Never
force the belt into a sheave with a screw driver or wedge. You will
damage the fabric and break the cords. It is recommended that the
pulley center distances be offset by ¾" for proper length. This
will allow the motor assembly to slide forward to remove belt and
backward for belt tension.
Belt Tension Measure the span length (center distance between
pulleys when belt is snug). Mark center of span, then apply a force
(6 to 9 Lbs on new belts) perpendicular to the span large enough to
deflect the belt 164" for every inch in span length.
Energy Recovery Wheel Maintenance Eight pie-shaped ERW segments,
are seated on stops between the segment retainer which pivots on
the wheel rim and secured to the hub and rim of wheel. Annual
inspection of the self cleaning wheel is recommended. With power
disconnected, remove UERV access panels (rear) and unplug [J150 and
P150] (Refer to wiring diagrams in this instruction manual). Remove
segment and wash with water and/or mild detergent.
To install wheel segments follow steps A through E . See Figure 17.
Reverse procedure for segment removal.
A. Unlock two segment retainers (one on each side of the selected
segment opening.
B. With the embedded stiffener facing the motor side, insert the
nose of the segment between the hub plates.
C. Holding segment by the two outer corners, press the segment
towards the center of the wheel and inwards against the spoke
flanges. If hand pressure does not fully seat the segment, insert
the flat tip of a screw driver between the wheel rim and outer
corners of the segment and apply downward force while guiding the
segment into place.
D. Close and latch each segment retainer under segment retaining
catch.
E. Slowly rotate the wheel 180o. Install the second segment
opposite the first for counterbalance. Rotate the two installed
segment 90o to balance the wheel while the third segment is
installed. Rotate the wheel 180o again to install the fourth
segment. Repeat this sequence with the remaining four
segments.

and press Enter. The restore should only take 15-20 seconds. Once
the restore is complete the SE unit control will reboot. Note: If
updating a version "H" board it may require two firmware updates to
take place. Please verify the active version of firmware after
updating.
If the unit does not reboot, restart cycle power to the unit and
wait again for re-boot start-up.
If loading more than one file, example upgrading CDR unit from
version 1, you should cycle power after loading the first file and
again after the last file is complete.
It is a good practice to conduct a "RE-LEARN" from within the menu
after the file(s) have been upgraded if the function of the unit
does not appear to be normal. Status> Alarms> Summary>

Enable- Make sure this is set to "Yes"
4. Once the ERV is set to "Enable" the ERV will operate any time
the unit is in the occupied mode. The ERV, if equipped with
pivoting wheel, will rotate the wheel out of the air stream anytime
the packaged units economizer enters the free cooling mode. In
order to test for proper operation the unit must see a call for
cooling (24 vac on the Y1 terminal) and an outdoor temperature of
55oF or less. If the outdoor ambient temperature is above 55oF the
unit may not enter free cooling. If the ambient temperature is
above 55oF the packaged unit can be forced into free cooling mode
by doing the following:
5. Scroll through menus by pressing down on joystick: Status>
Alarms> Summary> Commission> Controller> Update>
Details, under details press Enter then scroll to the Service menu
heading, press Enter then scroll to Inputs> NetworkInputs,
scroll to NetOAT and change it to a setting well below the 55oF
default by toggling the joystick left or right to increase/decrease
the value, then pressing Enter to store the new value. If the
setting is now 30oF for example the unit should go into free
cooling mode within a few minutes of the change. Note: Once the
NetOAT is forced to a temperature below 55oF it will remain at the
forced value for 15 minutes and revert back to default
settings.
For additional details on navigating, changing and operating the SE
unit control board please refer to the SE (Smart Equipment)
