(Wiring procedure)
(1) Connect the remote controller to the indoor unit remote controller wiring terminal plate (1, 2).
(Remote controller wiring)
(2) Connect the indoor units (U1, U2) and the outdoor units (1, 2). Connect the other outdoor units and indoor units
(with different refrigerant systems) in the same way. (Inter-unit control wiring)
Connect the remote controller communication wiring to the indoor units (U1, U2) for each refrigerant system.
(Interunit control wiring)
(3) Connect the remote controller communication wiring (2 wires) from the remote controller wiring terminal plate (1,
2) on the indoor unit (unit where the remote controller is connected) to the remote controller terminal plates (1,
2) on the other indoor units. (Remote controller communication wiring)
(4) Turn ON both the indoor and outdoor unit power and perform automatic address setting from the remote
controller. (For the automatic address setting procedure, refer to 2-8-4.)
NOTE
* Models with auxiliary heaters cannot be used for crossover wiring of the indoor unit power wires.
(Use a pull box to divide the wiring.)
Be sure to use the indoor unit temperature sensor (body sensor) when using this control. (Status at shipment.)
