Be careful to avoid miswiring when connecting the wires. (Miswiring will damage the units.)

Example: Using a wireless remote controller with a system
Leakage breaker
(Wiring procedure)
(1) Connect the communication wiring to 1 and 2 on the remote controller wiring terminal plate for units.
(2) Connect the inter-unit control wiring to 1 and 2 on the No.1 indoor unit terminal plate, and to 1 and 2 on the
outdoor unit terminal plate. Also connect the inter-unit control wiring between the indoor units.
(3) When the indoor and outdoor unit power is turned ON, automatic address setting is performed
(when there is only 1 outdoor unit or when the system address is "0").
NOTE * If the system address is "0", automatic address setting is performed when the power is turned ON
(in the case shown in Basic wiring diagram 1).
This requires approximately 4 – 5 minutes (when the outdoor / indoor unit ratio is 1:1 as shown in
Basic wiring diagram 1).
During automatic address setting, LED 1 and 2 on the outdoor unit control PCB blink alternately.
These LED turn OFF when automatic address setting is completed.
