A refrigeration controller that operates with two sensors, one for environment temperature and one that is set on the evaporator, controlling the end of the defrost more precisely. It has a clock for programming in real-time up to eight independent daily defrost actions, with a weekly calendar.

It has an internal sound alarm (buzzer), a switch to manually turn on and off the loads, digital inputs for external alarms, an internal clock to synchronize the defrost, and a compressor working hours counter (hour counter), indicating its maintenance time. It also performs monitoring of low voltage (between 12V and 24V) and also has an economic setpoint and internal memory (datalogger), which allows, for example, storing temperature variations of refrigerated transport throughout its journey.
