Your ventilation system is equipped with a heat recovery core specifically designed 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.

Stale air to outdoors

Fresh air to building

Stale air from building
22°C/72°F
When the outdoor 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 outdoor temperature. Defrost lasts 7 minutes for 100H model and
6 minutes for 200H model (or 10 minutes for both models 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.
