1. Enable the room temperature sensor selection in function setting, which will be described later.
2. Select either of the temperature sensor on the indoor unit or on the remote controller for temperature detection. (For how to configure the setting, refer to the operating manual.)

CAUTION
When select the “Remote controller setting”, if the detected temperature value between the temperature sensor of the indoor unit and the tempera-ture sensor of the remote controller varies significantly, 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 tempera-ture 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 sometimes. 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 temperature differ-ence is significant.
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.

1. Indoor room temperature sensor switching function (Only for Wired remote controller) The following settings are needed when use the control by Wired remote controller temperature sensor.
   (*…Factory setting)

• If setting No. is “00” : Room temperature is controlled by the indoor unit temperature sensor.
