Defrost Operation

Recirculating Damper Defrost (4 port models)

The recirculating damper defrost HRV has an electronically controlled damper defrost mechanism. The defrost timer is activated when the outside temperature drops below 27°F (- 3°C). A motor driven damper door mechanism closes off the supply air from outside allowing the exhaust air to recirculate through the unit. After the defrost period, the damper operates in the opposite direction to reopen the fresh air port. Defrost cycle repeats until the temperature again rises above 27°F (-3°C).

The damper defrost HRV has a fifth port for defrost. An electronically controlled damper defrost mechanism activates the defrost timer when the outside temperature drops below 27°F (-3°C). A motor driven damper door mechanism closes off the supply air from outside allowing room air to enter through the fifth port of the unit. After the defrost period, the damper operates in the opposite direction to reopen the fresh air port. Defrost cycle repeats until the temperature again rises above 27°F (-3°C).
