Your ventilation system will help eliminate poor air quality problems by
drawing the stale and humid air out of the house and replacing it with fresh
outside air. By eliminating accumulated pollutants and humidity, it maintains
an optimum air quality and an ideal relative humidity during cold season.
The unit is also equipped with a heat recovery core which reduces ventilation
costs in winter.
Shown with a forced air heating system; can also operate on its own.
Units equipped with a heat recovery core can reduce
ventilation costs in winter. The unit draws the heat from the
stale air and humid air before it is released and uses it to
heat the air coming in from outside. The recovery core is
designed in such a way that the stale air is never mixed with
the fresh air.
When the outside temperature is below -5°C (23°F), heat recovery creates frost in the core. To maintain its proper operation, the unit is
programmed to defrost the recovery core. The defrosting frequency varies according to outside temperature. Defrosting lasts 7 or 10 minutes,
according to outside temperature. During the defrost cycle, the unit shifts to maximum speed and the dampers close.
After defrosting, the unit returns to the operating mode previously selected by the user.
