1. DEFROSTING MODE When the outside temperature is below -5°C (23°F), recovery of heat in HRV units creates frost in the core. For ERV units, when the outside temperature is below -10°C (14°F), recovery of energy creates frost in the core. To maintain its proper operation, the unit is programmed to defrost the recovery core. The defrost frequency varies according to the outside temperature. During the defrost cycle, the unit shifts to maximum speed and the dampers close.
