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
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.

2. Scroll through menus by pressing down on joystick: Status> Alarms> Summary> Commission> PowerEx> ERV Enable- Make sure this is set to "Yes"
3. The economizer minimum setting must be set at 50% or greater. Status> Alarms> Summary> Commission> PowerEx> ERV 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.
