Defrost: When outdoor temperature falls to -5º C (23º 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.
Warranty: There is a 5-year warranty on all internal components. The heat recovery core has a lifetime warranty.
