CAUTION

Make sure at all times that the outside intake and exhaust hoods are free
from any snow during the winter season. It is important to check your unit
during a big snow storm, so it doesn’t draw in any snow. If this is the case,
please operate the unit in recirculation mode, or turn it OFF for a few hours.
Do not use your unit during construction or renovation of your house or
when sanding drywall. This type of dust may damage your system.
Since the electronic control system of the unit is incorporated with a
microprocessor, it may not operate correctly because of external noise
or very short power failure. If this happens, unplug the unit and wait
approximately 10 seconds. Then, plug the unit in again.

1. DEFROSTING MODE

When the outdoor temperature is below 23°F, recovery of heat in HRV units creates
frost in the core. For ERV units, when the outdoor temperature is below 14°F,
recovery of energy creates frost in the core.
To maintain its proper operation, the unit is programmed to defrost the recovery core. The
defrost frequency varies according to the outdoor temperature.

During the defrost cycle, the unit shifts to maximum speed and the dampers close.
After defrosting, the unit returns to the operating mode selected by the user.

2. CONTROLS

2.1 BOOTING SEQUENCES

HRV160 ECM AND ERV 140 ECM UNITS ONLY

The unit booting sequence is similar to a personal computer booting sequence.
Each time the unit is plugged after being unplugged, or a power failure occurs, the unit will
perform a 30-second booting sequence before starting to operate.
During the booting sequence, the integrated control LED will light AMBER for 10 seconds.
After that, the LED will light RED for the rest of the booting sequence. During this RED light
phase, the unit is checking and resetting the motorized damper position.
Once the motorized damper position completely set, the RED light turns off and the booting
sequence is done.
NOTE: No command will be taken until the unit is fully booted.

normal defrost) or AMBER (unit set in extended defrost) for 3 seconds, and then will shut
off for 2 seconds. After that, the LED will light RED for the rest of the booting sequence.
During this RED light phase, the unit is checking and resetting the motorized damper
