(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 control
communication wiring to the indoor units (U1, U2) for each refrigerant system. (Inter-unit control wiring)
(3) Connect the remote control communication wiring (2 wires) from the remote control wiring terminal board
(1, 2) on the indoor unit (unit where the remote controller is connected) to the remote controller terminal board
(1, 2) on the other indoor units. (Remote control 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 section "Automatic address setting using the remote
controller".)
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.)
