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)
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]
(Factory setting "0")
• Rotary switch [IU AD × 10]

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.

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.
Recommended range of external static pressure
ARUM24: 0 and 0.56 in WG (0 and 140 Pa)
ARUM30: 0 and 0.44 in WG (0 and 110 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.
