HRV/ERV Operational Modes Functionality
4
Off Mode: HRV/ERV fans are off. Defrost damper is closed to prevent cold air from entering the unit.
Normal Mode: In Normal mode HRV/ERV fans run and the unit exchanges indoor air with outdoor air. The
airflow exchange can be adjusted in four preset airflow values. Normal Mode is intended to be requested by the
user for long time HRV/ERV operation.
High Ventilation Mode: In High Ventilation Mode the fans run and the unit exchanges indoor air
with outdoor air, as in Normal Mode, but the airflow level is much higher. The airflow exchange can be adjusted
in four preset airflow values. High Ventilation Mode is intended to be requested by the user if he/she requires
quick air exchange in the house. The
can run in High in Ventilation mode for unlimited period of time
or for one of three preset timeout periods: 1,2 or 3 hours.
Energy Saving Mode: The will switch to Energy Saving Mode when it is requested by the User,
from the Wall Mount Unit. In Energy Saving Mode will automatically run in Auto mode 20 minute per
every 4 hours. The rest of the time the unit will stay in OFF mode. The defrost damper is closed to prevent cold-
air from entering the unit and the first running will start immediately after the
was set to Energy
Saving mode.
Humidity Mode: In Humidity Mode, the switches to High Ventilation Mode automatically when the
indoor humidity level exceeds the humidity set point, and returns to Normal Mode when the humidity level
becomes lower than the set point. The humidity level is measured by an external humidity sensor mounted in
the inlet of
station #3. The Humidity Mode can be disabled by the user by setting the humidity set
point to zero.
Recirculation Mode: When the User requests Recirculation Mode from the Wall Mount Unit, the
Control will place the supply fan into high speed with damper closed. Exhaust fan is off in this mode.
Manual Balancing Mode: (Optional for unit without automatic balancing) In manual balancing Mode, fan
speed can be manually adjusted by operating Wall Mount display in programming mode. (refer to page 7)

Defrost Mode: In Defrost mode the HRV/ERV re-circulates or only exhausts indoor air through the heat
exchanger, for a prescribed length of time over a prescribed time period. The unit automatically switches to
Defrost mode, when the outdoor air is below -5°C, and return to the last requested mode when the outdoor air
temperature becomes above -5°C. The period of time when the unit re-circulates or exhausts indoor air, will
lengthen as the external temperature lowers. While re-circulating, the unit runs in High Ventilation Mode with
supply fan shutting off and damper closed. While non-recirculating (exhausting), the exhaust fan runs in High
Ventilation Mode with supply fan shutting off and damper closed. Outdoor temperature is measured by a
thermo sensor, located in the HRV/ERV outdoor air intake duct. The Defrost Mode is an automatic mode which
cannot be enabled/disabled by the user, but the user can select from two defrost methods - recirculation or
non-recirculation and also one of nine preset maps for the defrost period length depending on the outdoor
temperature and type of heat exchanger / core. (see page 6)

The Timer Switch Unit consists of 3 LEDs and 1 push button. The Timer
Switch Unit can put the unit in to High Speed Mode for the set time on the

one Timer Switch is activated the Timer Switch having longest time wins
and only that Timer Switch can turn off the timer switch operation.
All 3 LEDs will blink to indicate error if the Control Board reports error or the
Timer Switch loses communication with the Control Board.
