Installation manual
¶
Do not twist the remote
sensor wiring with the
power wiring or run it in
the same metal conduit,
because this may cause
malfunction.
¶
Install the remote sensor
away from sources of
electrical noise.
¶
Install a noise filter or take
other appropriate action if
electrical noise affects the
power supply circuit of th
unit.
The mounting position for the remote sensor should be
located in an accessible place for control. Never cover
over the simplified remote controller or recess it into the
wall.
(1)
Insert a screwdriver or the like in the groove on
the lower side of the remote sensor body to pry
off the back case.
When using a wall box for flush mounting
¶
If local codes allow, this remote sensor can be
mounted using a conventional wall box for flush
mounting.
(2)
Use the two supplied M4 machine screws to
secure the remote sensor back case. Prior to
mounting, push open the cutouts in the back
case corre sponding to the holes in the wall box
using a screwdriver or the like. Use the spacers
and take care not to tighten the screws exces-
sively. If the back case will not seat well, cut the
spacers to a suitable thickness.
(3)
Connect the remote controller wires (3 wires) to
the electric cable from the remote sensor body.
(See “How to wire the remote sensor”)
CAUTION
When connecting the remote sensor wires,
check the terminal num bers in the indoor unit
to make sure that the wires are correctly con
nected.
(The remote sensor is damaged if 220 / 240 V
AC is applied.)
(4)
Fit the remote sensor body to the tabs of the back
case into the remote sensor body and mount it.
Remote sensor body
• Mount the remote sensor at a height of 1 to 1.5 meters

• Do not mount the remote sensor in a place exposed to
direct sunlight or a place exposed to outside air such
as near a window.
• Do not mount the remote sensor behind an object so
that it is separated from the air circulation of the room.
