[In the case of 29 refrigerant systems or less (when multiple air conditioners are included, their
number of refrigerant systems is also included)]
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.
