Trane CNT5482 Heat Pump Defrost Control Board

The Trane CNT5482 Defrost Control is an electronics defrost timing part that controls defrost cycles in commercial refrigeration. They include evaporator temperature, compressor run time, and ambient conditions which it constantly measures. According to these readings, the control smartly starts and stops the defrost cycles to ensure that there is no too much ice build up while at the same time using as little energy as possible. This reduces the amount of food products that go bad and increases system productivity.
