System Control
System control refers to the link wiring connection for control of simultaneous-operation multi systems, group
control, and mainsub remote controller control.
(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 section “Indoor unit remote controller main-sub setting” for K1 type.)
(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 Basic wiring diagram 1).
Connect the crossover wiring to 1 and 2 on the remote control wiring terminal board for units
(4-way, ceilingmounted, 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 board, and to 1 and 2 on the
outdoor unit terminal board. Also connect the inter-unit control wiring between the indoor units.
(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”).
Single type and simultaneous-operation multi system
Basic wiring diagram 1
(Wiring procedure)
Simultaneous-operation multi system
Up to 2 (Twin) indoor units can be connected to 1 outdoor unit for operation.
(However, coordinate the outdoor unit capacity and the total capacity of the indoor units.)
(It is not possible to connect individual remote controllers for independent operation.)
Be careful to avoid miswiring when connecting
the wires. (Miswiring will damage the units.)

Wall mounted units do not include a terminal board
for connecting a remote controller.
To connect the remote controller, a remote controller
cord is required.

* When using wall mounted units in a simultaneous-operation
multi system, connect the remote control communication
wiring to the remote controller connector (2P) on the main
unit, as shown in the diagram.

* 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.
