2-15-3. Automatic address setting from the Outdoor unit
If the power can be turned ON separately for the indoor and outdoor units in the system
(indoor unit addresses can be set without operating the compressor):
(1) Turn ON the indoor and outdoor unit power for refrigerant system 1.
Press and hold the automatic address setting button (black) for 1 second or longer at the outdoor unit where
the power was turned ON.
Communication for automatic address setting begins. LED 1 and 2 on the outdoor unit control PCB blink
alternately, and turn OFF when address setting is completed.
<Approximately 4 – 5 minutes are required.>
(2) Next, turn ON the power only at the indoor and outdoor units in a different system.
Press the automatic address setting button (black) on the outdoor unit.
LED 1 and 2 on the outdoor unit control PCB blink alternately, and turn OFF when address setting is
completed. Repeat the same procedure for each system and complete automatic address setting.
(3) Operation using the remote controller is now possible.
