(3) Connect the remote controller communication wiring (2 wires) from the remote controller wiring terminal plate
(R1, R2) on the indoor unit (unit where the remote controller is connected) to the remote controller terminal plates
(R1, R2) 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
