Requirement to install the remote sensor
Installation place
• Install the remote sensor at a position with height 1 to
1.5m from the floor, where the average temperature in
the room can be felt.
• Do not install the remote sensor at a place exposed to
the direct sunlight or direct outside air, such as a side of
window, etc.
• Do not install the remote sensor at a place behind
something or rear side of something, where air flow is
poor in the room.
• Do not install the remote controller near the freezing
box or refrigerator because water proof or drop-proof is
not applied to this remote controller.
• Be sure to set the remote sensor vertically on the wall
surface, etc.
How to install the remote sensor
NOTE 1 : Avoid to twist the remote sensor cable with the
power supply cable, etc. or to store them in the
same metal pipe, otherwise it causes a
malfunction.
NOTE 2 : Install the remote sensor apart from the
generation source of noise.
NOTE 3 : When noise is induced to the power source of
the indoor unit, some measures such as
mounting the noise filter is necessary.
• In case of using the remote sensor as a concealed type
1. Inserting a minus screwdriver, etc. into the groove at
the lower side of the remote sensor body, force open
the rear case to remove it.
2. Using the attached M4 screws (2 pcs.), fix the rear
case of the remote sensor. Before installation, press to
open the screw hole with a screwdriver, etc.
Fix it with the spacer, but not so strongly. If the remote
sensor does not fit closely to the wall, adjust it by
cutting off the spacer.
3. Connect the remote sensor cable (2 cores) to the
terminal numbers of the indoor unit.
(Applying AC 220/230/240V breaks the unit.)
4. Install the remote sensor body by matching to hooks
on the rear case and putting into the hooks.
How to perform cabling of the remote sensor
In case of using the remote sensor as a concealed type
• Connection diagram
• Non polarity, 2 core cable is used..
• Use 0.5mm² to 2 mm² cable.
Attached wire joint
(White, 2 pcs.)
1) Peel the sheath of the cable to be
connected by approx. 14mm.
2) Twist two cables and pressure-connect
them using a wire joint.
3) When an exclusive pressure-connecting
tool is not used or soldering connection
is used, apply insulation process with an
insulation tape.
