EAT RECOVERY CORE
Units with a heat recovery core (HRV Constructo 1.5ES and HRV Constructo 2.0ES units) are
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.

NERGY RECOVERY CORE
The ERV Constructo 2.0ES unit is equipped with an energy recovery core (enthalpic core) that can
reduce ventilation costs in winter as well as in summer.
1. During heating season, the unit draws humidity and heat from the stale air and transfers them,
in part, to the cold air entering the house, thus avoiding dryness problems and providing
maximum comfort (Example 1).
2. During cooling season, the unit reverses the process, preventing humidity from the outside air
from entering the house (Example 2).

EFROST MODE

When the outside temperature is below -5°C (23°F), recovery (of heat or energy) 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 for HRV
Constructo 1.5ES, 6 minutes for HRV Constructo 2.0ES and 10 minutes for ERV Constructo 2.0ES
models (or 10 minutes for all 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.
