How to install remote controller
NOTE 1 : Avoid to twist the remote controller cable with
power supply cable, etc. or to store them in
the same metal pipe, otherwise it causes a
malfunction.
NOTE 2 : Install the remote controller apart from the
generation source of noise.
NOTE 3 : When noise is contained to the unit power
supply, counter measures such as mounting
the noise filter is necessary.
• When using the remote controller as exposed,
install it at the wall surface where it can be fixed.
Fig. A
1. For removal and mounting of the remote controller
body and the rear case, refer to the item, “Using as
concealed type”.
2. Remove the lead wires wound to the fixing part of
lead wires of the remote controller body, remove the
connectors, and then connect the remote controller
cable (sold separately) to the connector section of the
remote controller body. Insert the remote controller
cable into the groove and form it, and wind it around
the fixing part of lead wires.
Notching the lower case (thin part of the upper center
part) with nipper, etc., pull out the remote controller
cables from this part. (Fig. A) (Refer to the item, “How
to perform cabling of the remote controller”.)
Connect cables of the remote controller after
check of terminal No. of the indoor unit so that
there is no miswiring. (Do not apply AC 200/230/
240V to the remote controller.)
3. Fix the remote controller body by two wood screws.
4. Using the cable clips (Accessory of remote controller
cable sold separately), fix the remote controller cable
to the wall surface.
• Non polarity, 2 core cable is used.
• Use 0.5mm² to 2mm² cable.

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.
• For cabling of the remote controller, use the
remote controller cable (sold separately).
1. Remove the lead wires wound to the fixing part
of lead wires of the remote controller body,
remove the connectors, and then connect the
remote controller cable (sold separately) to the
connector section of the remote controller body.
Insert the remote controller cable (sold
separately) into the groove and form it, and wind
it around the fixing part of lead wires.
2. When using the remote controller cable (sold
separately), refer to the Installation Manual
attached to the remote controller cable.

• How to install
For 2 remote controllers, install the remote
controllers in the following procedure.
1. Set one of two remote controllers as the master
remote controller. (At shipment from factory)
2. For the other remote controller, exchange the
remote controller address connector of the
master to sub remote controller on the P.C.
board. Under this condition, the other remote
controller functions as the sub controller.
• Basic wiring diagram
NOTE :
Connect cables without miswiring.
(Miswiring breaks the unit.)
• In a case to operate an indoor unit from the
remote controllers at two positions
• In a case to operate a group control of multiple
indoor units from the remote controllers at two
positions
*
Master and Sub remote controllers are
operable even if they are installed to any
indoor unit.
Remote controller test run setup
1. When the remote controller is used at the first time, it accepts an operation approx. 5 minutes after the power
supply has been turned on. It is not a trouble, but is because the setup of the remote controller is being checked.
2. Push
key after [TEST] has been displayed on LCD by keeping
button on the remote controller for
4 seconds or more.
• During the test run, [TEST] is displayed on LCD.
• The temperature cannot be controlled if [TEST] is displayed.
Do not use [TEST] in a case other than a test run, otherwise an excessive load is applied on the machine.
3. Use [TEST] in one of HEAT, COOL, and FAN operation modes.
NOTE : The outdoor unit does not operate for approx. 3 minutes after the power supply has been turned on or the
operation has stopped.
4. After the test run has finished, push
button again to check [TEST] on LCD has gone off.
(For this remote controller, a release function of 60 minutes timer is provided to prevent continuous test runs.)

Requirement for installation of
multiple remote controllers
“2 remote controllers” means that one or multiple
units are operated by the multiple remote
controllers.
(Max. 2 remote controllers can be set.)
Requirement to install the
remote controller
Installation place
• Install the remote controller 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 controller at a place exposed to direct
sunlight or direct outside air, such as a side of window, etc.
• Do not install the remote controller at a place behind something
or rear side of something where air flow is poor in the room.
• Do not install the remote controller in the freezing box or
refrigerator because water proof or drop-proof is not applied to
this remote controller.
• Be sure to set the remote controller vertically on the wall
surface, etc.
How to select the room temperature sensor
The room temperature sensors are equipped in the indoor unit and
remote controller.
One of two sensors works. Usually, the room temperature sensor
in the indoor unit is set to work. To select the sensor in the remote
controller side, refer to the following procedure.
1. Keep
,
SET
, and
CL
buttons pushed for 4 seconds or more.
NOTE) The UNIT No. displayed at the first time is the indoor
unit address of the master unit in the group control.
NOTE) Do not push
UNIT
(select) button.
2. Using the temperature setup buttons
/
, specify
↓
the item code
0032 .
3. Using the timer buttons
/
, change the set
↓
data from
0000 to 0001 .
4. Push
SET
button.
↓
(OK if the display changes from flashing to lighting)
5. Push
button.
The status returns to the normal status. In this time,
is
displayed in LCD.
NOTE 1 :
When using two remote controllers, the master remote controller
is recognized as
sensor though the temperature can be set
from either master or sub remote controller.
NOTE 2 :
In a group control, the
sensor does not work if the group
address is not set to the indoor unit of the master unit.
NOTE 3 :
When using the remote sensor together with the remote controller,
do not use the
sensor of the remote controller.
