1. YOUR UNIT AND ITS PURPOSE (CONT’D)
When the outdoor 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 outdoor 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.
