Simplifi ed Remote Controller Installation Guide-
lines
Place of installation
Mount the simplifi ed remote controller at a height of 3.3
to 5.5 ft above the fl oor where it can sense the average
temperature of the room.
Do not mount the simplifi ed remote controller in a place
exposed to direct sunlight or a place exposed to outside
air such as near a window.
Do not mount the simplifi ed remote controller behind an
object so that it is separated from the air circulation of the
room.
Mount the simplifi ed remote controller within the room be-
ing air conditioned.
The simplifi ed remote controller must be mounted on the
wall or other surface vertically.
SWITCHING THE ROOM TEMPERATURE SENSOR
The room temperature sensor is placed both in the indoor unit
and the simplifi ed remote controller respectively. Either sensor
can be used to sense the room temperature. The indoor unit
sensor is usually used.
If you use the simplifi ed remote controller to sense the room
temperature, switch the remote controller sensor switch (RCU.
SNS) on the P.C.B. of the simplifi ed remote controller from
OFF to
ON. See the diagram below.
NOTE
Even though the simplifi ed sub-remote controller switch is
switched from OFF to ON, the sub-remote controller can-
not detect the room temperature.
The standard remote controller cannot detect the room
temperature.

Do not twist the simplifi ed remote controller wiring with the
power wiring or run it in the same metal conduit, because
this may cause malfunction.
Install the simplifi ed remote controller away from sources
of electrical noise.
Install a noise fi lter or take other appropriate action if elec-
trical noise affects the power supply circuit of the unit.
* Use an electric junction box (supplied locally) (Fig. 3-41)
for fl ush mounting of the simplifi ed remote controller.
