1.1 AIR EXCHANGE (PRO250 & PRO225)

1. FUNCTIONS OF YOUR HEAT RECOVERY VENTILATOR
Your PRO250 or PRO225 Heat Recovery Ventilator eliminates the excessive humidity
problems by exhausting stale and humid air to the outside and by drawing in fresh air. Either
unit offers superior air quality and fresh air sensation, an important factor to overall comfort,
by eliminating the accumulation of
pollutants and humidity.
These units also come equipped with a heat recovery core which reduces ventilating costs
in winter.
The PRO250 and PRO225 Heat Recovery Ventilators are ventilation systems which carry
out the following operations:
During winter, these units recover the heat contained in the stale air before it is exhausted,
and transfer it to the fresh air drawn from the outside (reverse process in summer).
These units exhaust stale and humid air from the house and replace it with fresh air from
the outside.
1.2 HEAT RECOVERY (PRO250 & PRO225)
Example (in winter):
VF0015
STALE AIR TO OUTSIDE
4°C/39°F
FRESH AIR FROM OUTSIDE
0°C/32°F
FRESH AIR TO BUILDING
18°C/64°F
STALE AIR FROM BUILDING
22°C/72°F
1.3 RECIRCULATION (PRO250 ONLY)
During the recirculation mode, this unit stops to exchange air with the exterior. Continuous
recirculation is thus undertaken inside the home and insures the purification of the ambient
air. Two mechanical filters trap the large dust particles (those visible to the eye).
