WIRING EXAMPLE
-&CAUTION
Be sure to install an earth leakage breaker to the outdoor unit.
This is to avoid electric shocks or a fire.
For the wiring of outdoor units, refer to the installation manual
attached to the outdoor units. Confirm the system type.
• Pair type:
1 remote controller controls 1 indoor unit (standard system).
(Refer to Fig. 25)
• Simultaneous operation system:
1 remote controller controls 2 indoor units
(2 indoor units operates equally).
(Refer to Fig. 26)
• Group control:
1 remote controller controls up to 16 indoor units
(All indoor units operate according to the remote
controller). (Refer to Fig. 27)
• 2 remote controllers control:
2 remote controllers control 1 indoor unit.

1. Terminal numbers of outdoor and indoor units must be
matched.
2-1. Connect the remote controller only to the master unit.
2-2.
The remote controller needs to be wired only to the master
unit; it does not need to be connected to the slave units
through transition wiring. (Do not connect transition wiring
to the slave units.)
2-3. The indoor temperature sensor is effective only for indoor
units to which the remote controller is connected.

When implementing group control
• When using as a pair unit or as a master unit for
simultaneous operation system, you may carry out
simultaneous start/stop (group) control up to 16 units with
the remote controller. (Refer to Fig. 28)
• In this case, all the indoor units in the group will operate in
accordance with the group control remote controller.
• Select a remote controller which matches as many of the
functions (airflow direction, etc.) in the group as possible.
