6-3 Changing the Address of the Air Conditioner
In case of more than one air conditioner operating in the same room, it may be necessary to assign an address to each unit in order to
avoid operation conflicts. Address is set acting on the dip-switches located on the indoor PCB and on the remote controller.
The PCB settings must match the corresponding ones on the wireless remote controller.
