How to install the sensors
* The positions where the sensors can be installed are limited to the
corners (A) in Fig. 1. Therefore, for installation of the sensor units,
consider the direction when a panel is installed to the indoor unit.
1. Remove the suction grille.
2. Take off the screw fixing the corner cap and remove the corner cap
sliding it side-ward. (Fig. 2)

Fig. 2
3. The thermal insulation material is stuffed in the square hole
provided to pass through cables of the panel, so take off it once
and pass the cable out of the sensor of wireless remote controller
through the grille. Using a clamp, fix the cable with screws and
then be sure to stuff again the removed thermal insulation material
as original. (Fig. 3)
If the thermal insulation material is not stuffed, dewing may
happen.
Fig. 3
4. After cabling according to “How to perform cabling of sensor units”,
remain the cable length enough to remove the sensor unit and fix it
with screws using a clamp. (Fig. 3)
5. Install the sensor units to the panel. In this time, slide the panel so
that the hooks are fit in completely at 3 positions.
And also be careful not to pinch the cable. (Fig. 4)
Fig. 4
NOTES :
1. Avoid to twist the cables of the operation section with cables of the
power supply, etc. It causes a malfunction.
2. When noise is contained to the power supply of the indoor unit,
counter measures such as mounting the noise filter is necessary.

How to set the room temperature sensor
• The room temperature sensors are equipped in the indoor unit and
the wireless remote controller. One of two sensors works.
• The room temperature sensor is set to the indoor unit side at the
shipment from the factory. To select the sensor in the remote
controller, push the SENSOR button (Right figure) inside of the
remote controller cover and check “Main sensor” disappears from
LCD.
How to set the address switch
• When the multiple sensors are installed in the same room, an
address can be set to prevent cross communication.
• When replacing the battery and pushing SET button, the address of
the remote controller becomes [ALL] and the sensor is enabled to
receive signal regardless of setting of address switch of the
operation section.
• For selecting of the remote controller address, refer to Owner’s
Manual.
• Change the address of the sensor by removing screws of P.C. board
cover of the sensor unit. After then, fix the cover with screws using
a clamp.
Slide switch
• Check the slide switch in the battery box of the remote controller is
set to [S] / [A] at shipment from the factory.
Do not change the setting.
Test run
• How to use [TEST]
1. Turn No.1 of DIP switch [S003] on sensor P.C. board from OFF to
ON.
2. During the test run, all the indication lamps on LCD flash.
3. During the test run, the temperature cannot be controlled.
4. After the test run, be
sure to turn DIP switch 1
from ON to OFF and
check the indication
lamps do not flash.
Use [TEST] function
only for a test run,
otherwise the unit is
overloaded. Fix the
cover as original.
How to handle the remote contr oller
• In case using remote controller mounting to the wall, etc.
Check a signal is received correctly by pushing
button at the
position to be fixed.
Cautions for installation of the remote controller
• To operate the remote controller by fixing it to the wall, etc. with a
remote controller holder, turn on the fluorescent lamp, operate the
remote controller at the position to be fixed, check the air condi-
tioner normally operates, and then mount it.
• When the room temperature is sensed by the remote controller,
mount the remote controller paying attention to the following items.
• Place not exposed directly to cold or hot wind.
• Place not exposed directly to the sunlight.
• Other places where the remote controller is not influenced.
Explanation to customers
• Hand over the “Owner’s Manual” and “Installation Manuals” to the
customer after installation works.
• Explain usage and maintenance of the remote controller according
to “Owner’s Manual”.

Requirement
The control by two remote controllers is enabled by installing the
wireless remote controller with the wired remote controller for an
indoor unit.
(Max. 2 remote controllers of wireless or wired are installable.)
“2-remote controllers” controlling means that one or multiple units
are operated by the multiple remote controllers.
NOTES :
1. Upon confirmation of the terminal numbers of the indoor unit,
connect the remote controller cables without miscabling.
(If applied AC 220/230/240 Volt, damage the unit.)
2. The multiple wireless remote controller kits cannot concurrently be
used for an indoor unit.
3. When installing simultaneously the wireless remote controller with
the wired remote controller, set one of them as the sub remote
controller.
• When setting the wired remote controller as the sub, exchange the
address connector at the rear of P.C. board of wired remote
controller from master to sub remote controller.
• When setting the wireless remote controller as the sub, turn No.3 of
DIP switch [S003] on P.C. board of wireless remote controller
sensor unit from OFF to ON.
To operate an indoor unit by 2 remote controllers
* The indoor unit is operated if either wireless or wired remote
controller is set as master or sub remote controller.
