Heating

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

temperature sensor in the remote control unit.

The room temperature (and other information) is transmitted every 

5

 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 5

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 

not before than

 5 minutes

of compressor 

operation.

Thermo. ON : When the room temperature is below T – 1°C (T°C is set temperature).

Compressor

ON

Thermo. OFF : When the room temperature is equal to or above set temperature T°C.
