(Wiring procedure)
(1) Set the No. 1 wall-mounted indoor unit so that it can be operated by the wireless remote controller. (This is set
at the time of shipment.)
On the indoor unit control PCBs, set the No. 2 and following wall-mounted units to the sub remote controller.
(Refer to 10-16-5.)
GB
(2) Connect the crossover wiring to the lead wires (white/black) that extend out from the remote controller
connectors of the No. 1 indoor unit and other wall-mounted indoor units (as shown in the basic wiring diagram 1
above).
Connect the crossover wiring to 1 and 2 on the remote controller wiring terminal plate for units (4-way, ceiling-
FR
mounted, etc.) other than the No. 1 indoor unit.
(3) 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.
DE
(4) 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
IT
* 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).
PT
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.
