6. FIELD SETTING

There are 3 methods for address setting by field setting as follows.
Please set by either of the methods.
Each setting method is described in below (1) to (3).
(1) IU AD, REF AD SW settings: This section (refer to "6.1. Setting the address")
(2) Remote controller settings: Refer to the wired or wireless remote controller manual for
detailed setting information. (Set IU AD, REF AD SW to 0)
(3) Automatic address settings: Refer to the outdoor unit manual for detailed setting
information. (Set IU AD, REF AD SW to 0)
Be sure to turn off the power before performing the field setting.
Do not operate any switches other than prescribed, as it can cause the unit to operate
