This is a Fridge controller with four temperature bands each with a fixed temperature differential and with compressor ON/OFF Control. The controller also provides four alarm /status LED indication and an automatic defrost. (Automatically defrosts the freezer compartment for 30 minutes in every 12 hours) The controller uses extremely high reliability Thermometrics fridge probe sensors (10K NTC Thermistor). The operating voltage of the controller is from 90 VAC to 140 VAC with low voltage and high voltage cut OFF.
