EFROSTING
When the outdoor temperature is below 23°F, heat (or energy) recovery creates frost in
the core.
To maintain its proper operation, the unit is programmed to defrost its core. The defrost
frequency varies according to the outdoor temperature.
During the defrost cycle, the dampers close and the unit turns on high speed.
After defrosting, the unit returns to the operating mode selected by the user.
