The MR5 Controller can terminate defrost durations based on time or temperature. Temperature termination applications use a temperature sensor (SN2) that you install on the evaporator.
- Time-based defrost terminates the defrost cycle when the user-defined maximum defrost duration elapses.
- Temperature-sensor defrost terminates the defrost cycle when the temperature sensed at the evaporator sensor (SN2) reaches the user-defined defrost termination temperature.
- Temperature-switch based defrost terminates the defrost cycle when the temperature at the defrost termination switch on the evaporator reaches the switch’s cutout temperature.
