2. Processes and functions
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. 6 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 0.5°C above the set temperature T˚,
(T˚+0.5 °C):
Compressor ➞ ON
❑ Thermo OFF: When the room temperature is equal to or below the set temperature T˚:
Compressor ➞ OFF
❑ In case of wireless remote control model (GS type).
• The remote control unit sends the temperature signal to the air conditioner regularly at 3
minute intervals. If the signal from the remote control unit stops for more than 10 minutes
due to the damage of the remote control unit or other trouble, the air conditioner will
switch to the temperature sensor which is built in the indoor unit and control the room
temperature. In these cases, the temperature around the remote contorl unit may differ
from the temperature detected at the air conditioner’s position.
• If the remote control is located near a heat source, such as a space heater or in direct
sunlight, press the A/C SENSOR button to switch to the sensor in the indoor unit.
