The appliance keeps this performance till the difference is between temperature of room and the setted temperature is 3°C degrees,
than the control begin degrease the performance of appliance without any stage continuously to 50% of performance where the control
keeps it during this time till the temperature reaches the setted temperature. After these the thermostat sut off the appliance. Type of
