operation are fully functional. See Table 3 indicating
standard control operation.
1. With switch off, ERV/HRV is inoperative and the LED is
out.
2. With switch on LOW,
exchanges air with outside. If control is satisfied,
blower will run in low speed, otherwise, blower will run
on high speed. The LED is illuminated all the time.
3. With switch on INTERMITTENT, the ERV/HRV
exchanges air with outside on high ---speed blower,
and unit shuts down when control is satisfied. The ON
LED is illuminated all the time, and AIR EXCHANGE
LED is illuminated only when unit is running. This mode
is ideal for maintaining proper humidity levels when no
one is home.
5. Automatic Control Operation
This control contains an adjustable dehumidistat and push
button switch to cycle between 3 modes of operation.
There are 5 LEDs to indicate mode of operation (See Table
4).
Note:This control is designed to be used primarily with
installations which are independent of a forced air system.
1. Initially the switch is off. All LEDs are off and HRV is
inoperative
2. First push of mode button puts HRV into intermittent
mode. The HRV operates at high speed when there is
a call for dehumidification. Intermittent and exchange
LEDs are illuminated. When dehumidistat is satisfied,
HRV shuts down and exchange LED goes out.
3. Next push of mode button puts system in continuous
mode. Continuous and exchange LEDs remain on.
The HRV operates at high ---speed blower during calls
for dehumidification
dehumidistat is satisfied.
4. Next push of mode button and exchange puts system
in circulation mode. HRV operates in high speed at all
times. Circulation LED remains on. When there is a call
for dehumidification, exchange LED is on and HRV
exchanges air with outside. When dehumidistat is
satisfied, HRV dampers close which recirculates
indoor air. The exchange LED goes off.
5. The maintenance light illuminates every 3 months to
indicate filter should be cleaned. It is reset by opening
the door to the HRV.
Note: The standard and automatic controls sense humidity
not temperature. Either control must be located in an area
where it will continually monitor fresh air circulating within the
home. Install HRV wall control as close as possible to main
system thermostat and follow same guidelines as installing a
thermostat, (locate approximately 5 ft. [60 in.] above floor,
mount on an inside partitioning wall, etc).
Note: The HRV may be controlled using the Infinity system
control. The HRV may be connected using either a NIM or a
4 ---Zone Damper Module. See the appropriate instructions if
using the NIM of a 4 ---Zone Damper Module for connection
instructions.
Blower interlock relay is not needed for use with the Infinity
system control. The Infinity
simultaneously control the HRV and the indoor blower.
Push Button Timers may be used and are connected to the
HRV as shown in Figure 13. However, the Infinity system
should be set to continuous fan to ensure that the fresh air
is circulated in the home. In a Zoned System, at least one
zone should be set to continuous fan.

OPERATING THE HRV WITH THE EVOLUTION CONTROL
The ventilator has four settings in heating mode and three
settings in cooling mode.
HEATING:
AUTO --- the ventilator selects the speed based on
indoor humidity and outdoor temperature. It may cycle
on/off every 30 minutes depending on humidity and
outside temperature.
LOW --- low speed all of the time.
HIGH --- high speed all of the time.
DEHUM --- will only turn on if humidity is 3% over set
point. The speed is determined by indoor humidity and
outdoor temperature.
COOLING:
AUTO --- the ventilator selects the speed based on
indoor humidity and outdoor temperature. It may cycle
on/off every 30 minutes depending on humidity and
outside temperature.
LOW --- low speed all of the time.
HIGH --- high speed all of the time.
If the fan speed is set to Auto and the ventilator wants to
run, the fan speed will run at High continuous speed.
Otherwise, the fan will stay at the chosen continuous fan
speed.
6. Wiring
Remove top cover assembly from wall control and pass
thermostat wire through hole located on back of control
before attaching to wall. Connect Y, R, G, and B (yellow,
red, green and black) between wall control and HRV circuit
board. Following color code (See Fig. 11 and 12). Replace
top cover assembly.
Note: HRV wall control and circuit board operate on 12vdc.

7. Humidity Selector
The humidity selector is a built---in dehumidistat designed
to properly control the level of humidity in the house during
the winter months. This control helps avoid condensation
problems in upper northern regions where indoor humidity
is a problem during the winter season.
Note:This control is not to be confused with a dehumidistat
used during the summer months to control high relative
indoor humidity.
Table 4 recommends
condensation.
