1. YOUR UNIT AND ITS PURPOSE (

ECOVERY
Your ventilation system is equipped with a heat recovery core that is designed specifically to control
excess humidity and reduce ventilation costs by recovering the heat energy from the exhausted air,
and using that same heat energy to warm the fresh air being supplied. This heat recovery process
is accomplished in such a way that the stale air is never mixed with the fresh air.

EFROST MODE
When the outside temperature is below -5°C (23°F), heat recovery creates frost in the module. To
maintain its proper operation, the unit is programmed to defrost the recovery module. The defrost
frequency varies according to the outside temperature. Defrost lasts 7 minutes (or 10 minutes if set
on "Extented Defrost"). 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.
