7. FIELD SETTING
There are 3 methods for address setting by FIELD SETTING as follows.
Set by either of the methods.
Each setting method is described (1) to (3) below.
(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)
CAUTION
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

Rotary switch (REF AD ×10)...Factory setting “0”
In the case of multiple refrigerant systems, set REF AD SW as shown in the Table A for
each refrigerant system.
Set to the same refrigerant circuit address as the outdoor unit.
•
If working in an environ
-
ment where the wireless
remote controller can be
used, the addresses can
also be set using the
remote controller.
• If setting the addresses
using the wireless
remote controller, set
the indoor unit address
and refrigerant circuit
address to “00”.
(For information on set-
