8-2. Cooling

8-2-1. Room Temperature Control

● Room temperature control is obtained by cycling the compressor ON and OFF under control of the room

temperature sensor in the indoor unit.

● All information is transmitted every 3 minutes by the remote control unit to the controller in the indoor unit.

● 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 3 minutes or more of com-

pressor operation.

● Thermo. ON: When the room temperature is above T°F (T°F is set temperature).

Compressor ➔ ON

● Thermo. OFF: When the room temperature is equal to or below set temperature T – 1°F.
