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]
(Factory setting "0")
• 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
refrigerant system.
Set to the same refrigerant circuit address as the
outdoor unit.
• If working in an environ-

7.2. Custom code setting
• Selecting the custom code prevents the indoor unit mix-up. (figure below)
(Up to 4 codes can be set.)
• Perform the setting for both the indoor unit and the remote controller.

7.3. Static pressure mode
If the applicable static pressure does not match the static pressure mode, the static
pressure mode may be changed to another mode manually.
RC AD
Recommended range of external static pressure
ARUH72: 0.20 and 1.20 in WG (50 and 300 Pa)
ARUH96: 0.20 and 1.16 in WG (50 and 290 Pa)
It is necessary to set up a static pressure mode for each usage of static pressure.
Static pressure can be set at site.
Relation between set values and static pressure are as the following table.
• FUNCTION SETTING can be performed with the wired or wireless remote controller.
(The remote controller is optional equipment)
• Refer to the wired or wireless remote controller manual for detailed setting information.
