Model XR77CX, format 32x74mm, is microprocessor based controller, suitable for applications on low temperature ventilated refrigerating units. It has 4 relay outputs to control compressor, fan, defrost (which can be either electrical or reverse cycle -hot gas-) and light (configurable). It could be provided with a Real Time Clock which allows programming of up to 6 daily defrost cycles, divided into holidays and workdays. A “Day and Night” function with two different set points is fitted for energy saving. It is also provided with up to 3 NTC or PT1000 probe inputs, the first one for temperature control, the second one, to be located onto the evaporator, to control the defrost termination temperature and to manage the fan and the third one for condenser alarm management or the display. A digital input can be set to operate as fourth temperature probe
