EFROSTING
When the outside temperature is below 23°F, recovery of heat or 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.
After defrosting, the unit returns to the operating mode selected by the user.
