TEMPERATURE

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.

HEAT EXCHANGER FROSTING PREVENTION

The electronic control stops automatically the compressor each time the coil sensor TH 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.
