When the outdoor temperature is below 14°F, recovery of energy creates frost in the core.

To maintain its proper operation, the unit is programmed to defrost the energy recovery core.

For ERV100S model, during the defrost cycle, the unit keeps the same speed but stops to supply fresh air.

For ERV100SP model, during the defrost cycle, the dampers close but the unit speed can be set on high or low, according to your needs.

See point 2.4 for more details.

After defrosting, the unit returns to the operating mode selected by the user.
