2-1 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 remote control unit.
The figures on this and the next pages show 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, and Fig. 2 shows about the heating 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 (HEAT, COOL, or FAN) 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 2°F (4°F when set on body sensor) above
the set temperature T˚, (T˚+2°F or T˚+4°F when set on body sensor):
