Unit Description
5-8
When a Defrost cycle is initiated, the defrost relay energises the damper motor, pilot solenoid and heater contactor (during electric
standby operation on Model 50 units with optional electric heaters). If the unit is in Null mode on CYCLE-SENTRY or Electric
Standby operation, pressing the manual defrost key will initiate a manual defrost. The unit remains on Defrost until the evaporator
coil temperature increases to 14 C, at which time, the unit shifts back to the operating mode required by controller demand.
NOTE: If the controller calls for the Null mode (CYCLE-SENTRY or Electric Standby operation) while the unit is defrosting,
the unit will continue to operate until defrosting is complete. Then the unit will stop.
