- Defrost: When outdoor temperature falls to -5° C (23° F), an automatic timed defrost cycle is initiated. The fresh air motor will go to high speed and the exhaust air motor will turn off. A damper will shut off the cold supply port, directing ambient air through the core for defrosting. The unit will resume normal operation for a fixed duration, then the processor will read outdoor temperature and initiate defrost as necessary.
