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 flashes 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
indoor unit and the temperature 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 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
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 difference 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.
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 flash when the THERMO SENSOR button is pressed.
