Set up the address in the following procedure.
CAUTION
1. Set up address after wiring work.
2. Be sure to turn on the power in order of indoor unit → outdoor unit. If turning on the power in the reverse
order, a check code [E19] is output. When a check code is output, turn on the power again.

Automatic address : Setup from SW15 on the interface P.C. board of the outdoor unit
Manual address : Setup from the wired remote controller
