Automatic Address Setting (no compressor operation)
● Indoor and outdoor unit power can be turned ON for each system separately.
Indoor unit addresses can be set without operating the compressors.
Automatic Address Setting from Outdoor Unit
1. On the No. 1 (main) unit control PCB, set the unit No. switch (S007) to
On the No. 2 (sub) unit control PCB, set the unit No. switch (S007) to
On the No. 3 (sub) unit control PCB, set the unit No. switch (S007) to
2. To set the number of outdoor units on the outdoor main unit control PCB, set the No. of outdoor units DIP switch (S006) to

5. Turn on power to all indoor and outdoor units in the system.
6. Short-circuit the automatic address pin at the outdoor main unit (CN054) for 1 second or longer, then release it.
(Communication for automatic address setting begins.)
* To cancel, again short-circuit the automatic address pin (CN054) 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.
(Automatic address setting is completed when LEDs 1 and 2 on the outdoor main unit control PCB turn OFF.)
7. Next turn the power ON only for the indoor and outdoor units of the next (different) system. Repeat steps 1 – 5 in the same way to
complete automatic address settings for all systems.
8. Operation from the remote controllers is now possible.
* To perform automatic address setting from the remote controller, perform steps 1 – 5, then use the remote controller and
complete automatic address setting.
● Refer to "Automatic Address Setting from Remote Controller."
