7. 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 (7.1. 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)

7.1. Setting the address
Manual address setting method
• The indoor unit address and the refrigerant circuit address can also be set up through
the wireless remote controller
CAUTION
Be sure to turn OFF the power before performing the
fi
eld setting.
• Please set it according to the following procedures when setting manually.
