Controller for frozen foods that automates the defrosting process according to the needs of the facility (intelligent defrosting), providing energy savings. It operates with two sensors, one for room temperature and the other, fastened to the evaporator, that controls defrosting completion and fan restarting. The room temperature control has a normal setpoint and an economic setpoint, in addition to the fast freezing functionality and alarm functions indicating that the door is open. It features two digital inputs. One of these inputs may be configured as sensor 3* to monitor the condenser temperature and disconnect the control outputs in case of an alarm or control defrost termination in a second evaporator. It also features a digital filter, which is intended to simulate an increase of the mass of the room temperature sensor (S1), thus increasing its response time (thermal inertia), and avoiding unnecessary compressor activations. Its main feature is to have a powerful relay to drive compressors up to 2HP and the defrost output has a current capacity of 10 Amp.
