temperature sensor in the remote control unit.

FUNCTION
•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
compressor operation.
•Thermo ON: When the room temperature is above T + 1°C (T°C is set temperature).
Compressor ➔ ON.
•Thermo OFF:When the room temperature in equal to or below set temperature T°C.
Compressor ➔ OFF.
