NOTIFICATION

When using the equipment for the first time, the remote controller will not accept any commands for a short period of time.

•Automatic address

•While automatic addressing no operations can be performed on the remote controller.

•Automatic addressing will take a maximum duration of 10 minutes (generally 5 minutes).

•Upon turning on the unit after completion of automatic addressing, a maximum period of

10 minutes (generally 3 minutes) are required prior to the start up operation of the outdoor unit.

All indoor units are shipped from factory as standard. Change if necessary.

To change the setup use the main remote controller (wired remote controller).

*The setup change for wireless remote controller, sub remote controller or a unit without a controller (Centrally controlled.) is not possible. In such cases, temporarily install a separate main remote controller.
