4.2. S etting the room temperature detection
location
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 detection location of the room tempera-
ture can be selected from the following 2
methods. Choose the detection location that
is best for the installation location.
The temperature sensor of the indoor unit or
the remote controller can be used to detect
(e)
the room temperature.

When the remote controller is not used, the following functions cannot
be used.
• [Custom Auto] of the operation modes: Refer to operating manual.
• [Away Setting]: Refer to operating manual.
4.3. Installation space
• Do not embed this remote controller in a wall.
• Recommendation installation height of the remote controller is 55 in (1.4
m) (from the floor surface to the bottom of the remote controller).
• Even when you install a remote
controller to one of a switch box
and the surface of a wall, secure
the space shown in following
figure. When there is insufficient
space, there may be remote con-
troller sensor misdetections and
remote controller removal may be
difficult.
* Please secure enough space where a flat-blade screwdriver to take off a
case can be inserted.
