NOTA
●
The control circuit will not attempt to turn the compressor ON until the compressor has been OFF for at least
3 minutes. To protect the compressor from stalling out when trying to start against the high side refrigerant
pressure, the control circuit has a built-in automatic time delay to allow the internal pressure to equalize.
●
As a protective measure, the control circuit switches the compressor OFF after 5 minutes or more of com-
pressor operation.
●
Thermo ON:
When the room temperature is above T + 1 °C (T°C is set temperature).
