Automatic Defrost Cycle Features
All models offer a non- -electric defrost cycle feature which
prevents frost and ice buildup within the heat recovery core.
When the outside air temperature falls below 23_F (- -5_C) it is
electronically sensed and the dampers close the outside air ports.
This allows warm indoor air to recirculate within the heat
recovery core. The frequency of this cycle increases as the outside
air temperature decreases.
