ECOVERY
This unit is equipped with a
heat recovery core
, specifically designed to
reduce ventilation costs by recovering the heat energy from the exhaust 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.
Example (in winter):
VF0015
INSIDE
OUTSIDE
STALE AIR TO OUTSIDE 25°C/77°F
FRESH AIR FROM OUTSIDE 0°C/32°F
FRESH AIR TO BUILDING 35°C/95°F
STALE AIR FROM BUILDING 60°C/140°F
(During heating mode)
When the outside temperature is below the freezing point, heat recovery
creates frost in the module. If the furnace blower is set to operate
intermittently, the heat coming from the stale air will prevent unit frosting.

CAUTION
When the outside temperature is under -10°C (14°F), the furnace must
operate intermittently in heating mode to prevent frost accumulation
inside the unit.
