8-4. Address setup
This product requires address setup before operation.
Follow this procedure for address setup.
8-4-1. Precautions
(1) Address setup is not performed simply by turning on the power supply.
(2) For indoor units, address setup can be done either by manual address setup or by automatic address setup:
Automatic address setup: Setup from SW15 on the interface P.C. board of the outdoor unit
Manual address setup: Setup from the wired remote controller. (For details, refer to “8-4-3. Address setup
procedure.”)
(3) Automatic setup usually takes about 5 minutes per line. In some cases, however, it may take up to 10 minutes.
(4) It is unnecessary to operate the air conditioner to achieve address setup.
