8. 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.

The room temperature is detected by the indoor unit temperature sensor.
(1) When the “
” button is pressed, the lock
display

A
Indoor unit
B. Indoor unit/remote controller setting (room temperature sensor
selection)
The temperature sensor of the indoor unit or the remote controller can be
used to detect the room temperature.
When use this function, set “Indoor room temperature sensor switching
function (Function Number:42)” of “9. FUNCTION SETTING” to “Yes(01)”.
(1) Enable the room temperature sensor selection in FUNCTION SETTING,
which will be described later.
(2) Press the “
” 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 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 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 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
example 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
“
” button is pressed.
