Application
Energy Recovery Ventilators (ERV) are used with units
equipped with a return damper assembly. These wheels
conserve energy by mixing warmer air with cooler air in the
following manner:
Recovery Wheel Mode
The Recovery 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 (ERW) within the cassette
frame work. In winter, the ERW 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

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 economizer 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 ERV 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
4
heat load.
During both the summer and winter, the ERV 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
ERV 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.
Low Ambient Kit is appropriate for climates with limited HVAC
system operation when outdoor temperatures are below 15oF.
The frost threshold is the outdoor temperature at which frost
will begin to form on the ERV wheel. For energy recovery
ventilators, the frost threshold is typically below 15oF. Frost
threshold is dependent on indoor temperature and humidity.
The table shows how the frost threshold temperatures vary
depending on indoor conditions.

INDOOR RH AT 70ºF
FROST THRESHOLD
TEMPERATURE
20%
0ºF
30%
5ºF
40%
10ºF
Because Energy Recovery Ventilators have a low frost
threshold, frost control options are not necessary in many
climates. Where outdoor temperatures may drop below the frost
threshold during the ERV operational hours, exhaust only frost
control option is available.
Low Ambient Kit
Low Ambient Kit turns off the supply blower when outdoor
temperatures fall below the frost threshold. Exhaust Only set
points are field adjustable with a factory supplied thermostat.
Supply fan operation is automatically restored when the exhaust
air temperature rises above the thermostat set point. Provisions
for introducing make-up air into the building when the supply
blower is off to avoid depressurization should be considered.
Recovery 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 ERV.
See Figure 2.
System Check
1. Disconnect main power.
2. Turn thermostat to “Cont” for blower operation.

3. Restore power to unit. Observe ERV wheel rotation and both
fresh air and exhaust air blowers will operating.
Note: If Low ambient kit is used the jumper between TB375 & 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 ERV (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 ERV.
c) Reapply power.
A. Return Damper Settings
Manually adjust position of dampers. This is accomplished by
loosing and tightening set screw on positioning rod.
B. Blower Speed Adjustment
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 read
ings will need to be read across the ERV. See Figure 3 for
location to take pressure readings.
1. Disconnect main power to unit before making adjustment
to economizer and/or ERV unit.
2. Replace ERV control access cover.
3. Set thermostat to normal operating position.
4. Restore power to unit.
Maintenance
Motor Maintenance
All motors use prelubricated sealed bearings; no further
lubrication is necessary.
Mechanical Inspection
Make visual inspection of dampers, linkage assemblies and erv
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 Wheel Maintenance
Four pie-shaped ERW segments are seated on stops between
the stainless steel spring retainers, secured to the hub and
rim of wheel. Annual inspection of the self cleaning wheel is
recommended. With power disconnected, remove ERV access
panels (rear) and unplug (J150 & P150). Refer to wiring
diagram in this instruction manual. Each segment is secured in

place by a stainless steel spring retainer located on wheel
rim. Remove one end of the stainless steel spring retainer from
the slot in the wheel rim and remove. Do the same on the next
retainer. Remove segment and wash with water and/or mild
detergent. Replace segment by reversing the above procedure.
See Figure 4. Discoloration and staining of ERV segment does
not affect its performance. Only excessive buildup of foreign
material need be removed. If the segment appears excessively
dirty, it should be cleaned to ensure maximum operating
efficiency. Thoroughly spray plastic surface with household
cleaner such as Fantastic→ or equivalent middle detergent
and gently rinse with warm water using a soft brush to remove
heavier accumulation. Shake excess water from segment and
replace in reverse of removal instructions.

control.
Figure 2
Mode of Operation
The mode of operation is selected with the adjustment of a
jumper. The jumper is located at the lower center position of the
circuit board. The following diagram details the jumper location
for each mode of operation:
Temperature Control (See Figure 1)
The temperature mode of operation incorporates one sensor
located in the fresh air intake of the ERV. The Start Stop
Jog sequence is activated when the outside air temperature
is between 70°F and 40°F. The SSJ module provides two
potentiometers in order to adjust the Low and High temperature
range of the start stop jog sequence. To adjust the High
temperature range, place a Multimeter on the COM and HIGH
test points. Use a screw driver to adjust the potentiometer
to the desired VDC representing the temperature. The Low
temperature range is adjusted by placing a Multimeter on
the COM and LOW test points with the adjustment of the
potentiometer to the desired VDC representing temperature.
The VDC can be calculated for a desired temperature using the
following formula: VDC = 0.1429 x (Temperature) - 5.7143.
Figure 1
Enthalpy and Temperature (See Figure 3)
The combination mode of operation will activate the Start Stop
Jog sequence when the Enthalpy meets the control curve setpoint and the outside air temperature is between the Low and
High temperature setpoint.
LED and Test Switch
There is a +5V LED indicating the module is wired and powered properly. If the LED is not illuminated check the wiring and
power supply. The SSJ LED indicates when the SSJ module
has entered the start stop jog sequence. The RELAY LED illuminates when the relay is activated cutting power to the relay
contacts.
The pushbutton on the module is used to test the relay. When
the pushbutton is activated the LED under the button illuminates. The LED indicates test mode of the relay is operating.
The SSJ sequence will not operate while the module is test
mode.
Figure 3
Enthalpy Control (See Figure 2)
The enthalpy mode of operation incorporates one enthalpy sensor located in the fresh air intake of the ERV. The SSJ module
compares the outdoor enthalpy to a preselected set point. The
value of the set point can be identified on a psychometric chart
with the standard control curves as A, B, C or D. The set point
can be selected as an aggressive set point A for higher levels
of free cooling or a conservative set point D for lower levels of
free cooling. The Enthalpy sensor provides a 4-20 mA (0-100%)
signal proportional to the selected control curve A, B, C, or D.
The SSJ module begins the start stop jog sequence when the
Enthalpy sensor reports 60%. The Enthalpy 60% setpoint for
each control curve is detailed in the following table:
