WALL CONTROL
Step 1.—Location
The ERV/HRV wall control is unique to this unit. The ERV/HRV
will not operate without it. This control senses humidity not
temperature. It must be located in an area where it will continually
monitor fresh air circulating within the home. Install ERV/HRV
wall control as close as possible to main system thermostat and
follow same guidelines as installing a thermostat (locate
approximately 5 ft. above floor, mount on an inside partitioning
wall, etc.)
Step 2.—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 ERV/HRV connector following color code (See
Fig. 8 and 9). Replace top cover assembly. In Fig 9, item A shows
a correctly inserted wire, item B shows an incorrectly inserted wire.
NOTE: ERV/HRV wall control and circuit board operate on 12vdc.

Step 3.—Operation
The ERV/HRV wall control has 4 basic modes of operation, OFF,
LOW, HIGH, and INTERMITTENT. Be sure that all modes of
operation are fully functional. See Table 1 indicating standard
control operation.
1. With switch off, ERV/HRV is inoperative and the LED is
out.
2. With switch on LOW, ERV/HRV continuously 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 idealfor
maintaining proper humidity levels when no one is home.
Step 4.—Humidity Selector
The humidity selector is a built-- in control designed to properly
control the levelof 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 monthsto control high relative indoorhumidity.
Table 2 recommends humidity levels to avoid condensation.
Step 5.—OneTo uch Control
The OneTouch control can be used as the primary wall control for
theERV/HRV.Thiscontrolwillstep through themodes of operation
with consecutive presses of the button. The LED indicates which
mode is currently selected, Off, Intermittent, Low, or High.
Step 6.—Latent Control
NOTE: To ensure highest degree of humidity control in cooling
season, the INTERMITTENT mode should be used. See Table 1
and reference LOW and INTERMITTENT control operation listed
above.
NOTE: The ERV/HRV may be controlled using the Infinity system
control. The ERV/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.
The Infinity system control will simultaneously control the
ERV/HRV and the indoor blower.
Push Button Timers may be used and are connected to the
ERV/HRV. 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 onezone shouldbe setto continuousfan.
OPERATING THE ERV/HRV WITH
THE INFINITY 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 willrun atHigh continuous speed.Otherwise, thefan willstay
at the chosen continuous fan speed.
