ON-SITE SETTING AND OTHERS
(2) Manual setting/change of indoor unit refrigerant line addresses
[In the case of 30 refrigerant systems or more (when multiple air conditioners are included,
their number of refrigerant systems is also included)]
Regarding refrigerant systems up to No. 29, manual setting/change is the same as that on the
previous page.
• Refrigerant address “1” is assigned to all indoor units except for group control by the auto address
setting after system power on. Therefore, change refrigerant line address of each refrigerant
system using the wired remote controller.
• Also change indoor unit addresses so as to avoid duplication of indoor unit numbers.
* For changing/setting refrigerant line addresses by wired remote controller, refer to
11
ADDRESS
SETTING.
* Change refrigerant line address of all indoor units connected directly to the central controller to
“30”.
These indoor units are under twin or triple control, also change the refrigerant line address of
follower indoor units to “30”.
* Change indoor unit addresses so that they are not duplicated.
