NOTES
1. If the compressor is turned off, the control circuit sets an automatic minimum 3 minutes delay to protect
the compressor from stalling out when trying to start against the high side refrigerant pressure.
2. If the room temperature is 1°C above the set temperature, the compressor starts working if this has been
OFF for at least 3 minutes.
3. If the room temperature is the same or under the set temperature the compressor stops working.
5-2 Heat Exchanger Frosting Prevention
The electronic control stops automatically the compressor each time the coil sensor TH1 reaches a
temperature of 1 °C for 8÷10 minutes long, the compressor starts again automatically when the
temperature of heat exchanger reaches 8 °C. the fan goes "ON" working at the set speed.
