(Wiring procedure)
(1) Connect the crossover 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.
