Fig. 10 -- Typical Wall Control
Operation
The Standard and Latent wall controls have 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 ex-
changes air with outside on high--speed blower, and unit
shuts down when control is satisfied. The ON LED is illu-
minated all the time, and AIR EXCHANGE LED is illumi-
nated only when unit is running.
Humidity Selector
The humidity selector is a built--in control designed to properly
control the level of humidity in the house during the winter and
summer 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 2 recommends humidity levels to avoid condensation.

OneTouch Control
The OneTouch Control can be used as the primary wall control for
the ERV/HRV. This control will step through the modes of
operation with consecutive presses of the button. The LED
indicates which mode is currently selected, Off, Intermittent, Low,
or High.
NOTE: OneTouch Control does not have a humidity selector.
NOTE: OneTouch Intermittent mode exchanges air on low speed
for 20 minutes per hour.
Latent Control
NOTE: For Latent Controls used with ERV;s, to ensure highest
degree
of humidity control in cooling season, the
INTERMITTENT mode should be used.
Integrated Control
All units are equipped with an integrated control, located under the
unit, in front of the electrical compartment. Use the push button (1)
to control the unit. The LED (2) will then shows on which mode
the unit is in. Integrated Control overrides Wall Control function.
When LED is off, ventilator responds to Wall Control command.
See Fig. 11.
WARNING
Risk of electric shock. Before performing
any maintenance or servicing, always
disconnect the unit from its power source.

If a problem occurs during the unit operation, its integrated control
LED (2) will blink. The color of the blinking light depends on the
type of error detected. Refer to Troubleshooting for further details.
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 or 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 one zone should be set to continuous
fan.
