When connecting multiple indoor units to 1 refrigerant system, set the address at IU AD
SW as shown in the Table A.
(2) Refrigerant circuit address
Rotary switch (REF AD × 1)...Factory setting "0"

In the case of multiple refrigerant systems, set REF AD SW as shown in the table below
for each refrigerant system.
Set to the same refrigerant circuit address as the outdoor unit.
• If working in an environment where the wireless remote controller can be used, the ad-
dresses 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".
