6-5. Wiring System Diagram for Multiple Remote
Control
■ When Installing Multiple Remote Controllers
This multiple remote controller system is used for
operating the unit(s) at different positions. (A maximum
of 2 remote controllers can be installed.)
● Setting method
To execute this control, make the setting according
to the following procedure.
(1) Of the two installed remote controllers, make one
the main remote controller (factory-shipped
state).
(2) On the other remote controller, change the
address connector on the PCB from main to sub
position.
In this state, it functions as a sub-remote controller.
● Basic wiring diagram
Install wiring correctly
(incorrect wiring will damage
the equipment).
● To operate 1 indoor unit with 2 remote controllers
set at different places.

6-6. How to Switch the Indoor Temperature Sensor
The indoor unit and the remote controller both contain
an indoor temperature sensor. The sensors on either
unit can be used but normally only the sensor set on
the indoor unit is used. However, use the following
procedure if you must use the sensor on the remote
controller.
(1) Hold down the + + buttons for at least
4 seconds.
Note: The Unit No. first displayed is the main indoor
unit address for group control.
Note: Do not press the button.
(2) Select CODE NO. 32 with the Temp.setting ( )
/ buttons.
(3) Change the set data from 0000 to 0001 with the
Timer ( ) / button.
(4) Press the button. (Setting is OK if the blinking
display changes to a lit up display.)
(5) Press the button.
This is the usual off condition. At this time,
(remote controller) appears on the LCD display.

CAUTION
NOTE
* 1 If using 2 remote controllers, either one (main or
sub-remote controller) can be used to make setting
but only the main unit functions as the remote
controller sensor.
* 2 The remote controller sensor will not function
during group control unless the group address is
set in the main remote controller indoor unit.
* 3 Do not use remote controller switch for the remote
control sensor if the remote sensor is being used
jointly with the remote controller switch.
