Automatic address setting from the outdoor unit
When there are multiple outdoor units as shown in basic wiring diagram 2
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 AUTO ADD (CN041) pin 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.
(2) Next, turn ON the power only at the indoor and outdoor units in a different system.
Short-circuit the AUTO ADD (CN041) pin for 1 second or longer 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.
