If the power can be turned ON separately for the indoor and outdoor units in each system:
●
The indoor unit addresses can be set without running the compressor.
Be sure to use a jig for short-circuiting.
●
(1) Turn on the indoor and outdoor unit power for refrigerant system 1.
Short-circuit the A.ADD pin.
Communication for auto address setting begins.
LED 1 and 2 on the outdoor unit control PCB blink alternately, and turn OFF when address setting is completed.
(2) Next, turn ON the power only at the indoor and outdoor units in a different system. Short-circuit the A.ADD pin.
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 auto address setting.
(3) Operation using the remote controller is now possible.
