11. PROCESSES AND FUNCTIONS

(1) Room Temperature Control

The Unit adjusts room temperature by turning the outdoor unit’s compressor ON and OFF. This process is controlled by the thermostat located in the indoor unit.

The figures shows how each part of the system performs when the room temperature changes and the thermostat activates the compressor to start (thermo ON) or stop (thermo OFF). Fig. 1 shows about the cooling cycle.

Chart Summary and Explanations

Once the compressor starts, it keeps running for 5 minutes.

Once the compressor stops, it will not start running again for 3 minutes.

If you change the operation mode during the cooling cycle, the control circuit stops the compressor for 3 minutes.

For 5 minutes after the compressor is first turned on, and for 3 minutes after it is turned off, the compressor is not controlled by the room sensor.

Thermo ON: When room temperature rises 1 °F above the set temperature T˚, (T ˚+1 °F):

Compressor ON

Thermo OFF: When the room temperature is equal to or below the set temperature T˚:

Compressor OFF
