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:
(3) Automatic address settings: Refer to the outdoor unit manual for detailed setting
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
improperly or malfunction.
Use an insulated screwdriver to set the DIP switches.

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
Use an insulated screwdriver to set the DIP
switches.
Setting
Indoor unit address
• Rotary switch [IU AD × 1]
CNB
(Factory setting "0")
01
• Rotary switch [IU AD × 10]
(Factory setting "0")
When connecting multiple indoor units to 1
refrigerant system, set the address at IU AD SW
as shown in the Table A.
Refrigerant circuit address
• Rotary switch [REF AD × 1]
(Factory setting "0")
• 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
CNB
refrigerant system.
01
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-
ting using the wireless
remote controller.)
* Do not set the indoor
unit address (IU AD
SW) at 64 to 99.
It may result in failure.
