SETTING THE ROOM TEMPERATURE DETECTION 
LOCATION

The detection location of the room temperature can be selected from the following 2 examples. 

Choose the detection location that is best for the installation location.

A.  Indoor unit setting (factory setting)

The room temperature is detected by the indoor unit temperature sensor.

(1)  When the THERMO SENSOR button is pressed, the lock display 

fl

 ashes because the 

function is locked at the factory.

A

Indoor unit

B.  Indoor unit/remote controller setting (room tempera-

ture sensor selection)

The temperature sensor of the indoor unit or the remote controller can be used to detect 

the room temperature.
(1)  Enable the room temperature sensor selection in FUNCTION SETTING, which will be 

“(5) Indoor room temperature sensor switching function”.

(2)  Press the THERMO SENSOR button for 5 seconds or more to select the temperature 

sensor of the indoor unit or the remote controller.

B

Indoor unit

 

CAUTION

When select the “Remote controller setting”, if the detected 
temperature value between the temperature sensor of the in-
door unit and the temperature sensor of the remote controller 
varies signi

fi

 cantly, it is likely to return to the control status of 

temperature sensor of the indoor unit temporarily.

As the temperature sensor of remote controller detects the temperature near the 
wall, when there is a certain difference between the room temperature and the 
wall temperature, the sensor will not detect the room temperature correctly some-
times.
Especially when the outer side of the wall on which the sensor is positioned is 
exposed to the open air, it is recommended to use the temperature sensor of the 
indoor unit to detect the room temperature when the indoor and outdoor tempera-
ture difference is signi

fi

 cant.

The temperature sensor of the remote controller is not only used when there is a 
problem in the detection of the temperature sensor of the indoor unit.

NOTES

If the function to change the temperature sensor is used as shown in examples A (other 
than example B), be sure to lock the detection location. If the function is locked, the lock 
display 

 will 

fl

 ash when the THERMO SENSOR button is pressed.
