Indoor and outdoor unit power cannot be turned ON for each system separately.
In the following, automatic setting of indoor unit addresses is not possible if the compressors are not operating.
Therefore perform this process only after completing all refrigerant tubing work.
Automatic address setting can be performed during Cooling operation.
Automatic Address Setting from Outdoor Unit
1. Perform steps 1 – 2 in the same way as for .
3. Turn the indoor and outdoor unit power ON at all systems.
↓
4. To perform automatic address setting in , on the outdoor unit control PCB in the refrigerant system where
you wish to set the addresses, short-circuit the mode change 2P pin (CN50). At the same time, short-circuit the automatic
address pin (CN51) for 1 second or longer, then release it. (Be sure to perform this process for one system at a time.
Automatic address settings cannot be performed for more than one system at the same time.)
↓
(Communication for automatic address setting begins, the com p ressors turn ON, and automatic address setting in
Cooling mode b egins. )
(All indoor units operate.)
↓
(Automatic address setting is completed when the compressors stop and LEDs 1 and 2 on the outdoor unit control PCB turn
OFF.)
5. At the outdoor main unit in the next (different) system, short-circuit the automatic address pin (CN51) for 1 second or longer,
then release it.

(During automatic address setting, “SETTING” is displayed on the remote con-
troller. This message disappears when automatic address setting is completed.)
5. Repeat the same steps to perform automatic address setting for each successive system.

Case 3B
* To cancel, again short-circuit the automatic address pin (CN51) for 1 second or longer, then release it.
The LED that indicates automatic address setting is in progress turns OFF and the process is stopped.
Be sure to perform automatic address setting again.
