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 environment 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”.

Do not set the indoor unit address (IU AD SW) at 64 to 99.
It may result in failure.

Since the remote controller address settings are automatically confi gured, you do not
need to confi gure them.
If confi guring manually, it is necessary to confi gure both the indoor unit and the remote
controller.
For details, please refer to the remote controller manual.
7.2. Custom code setting
Selecting the custom code prevents the indoor unit mix-up.
(Up to 4 codes can be set.)

. Static pressure mode
CAUTION
If the applicable static pressure does not match the static pressure mode, the static
pressure mode may be changed to another mode manually.
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.

* Please refer to FAN PERFORMANCE CURVE within Design & Technical Data for the fea-
tures of each setting.
* If the Setting Number in AR96 is configured to “30”, the operation is the same as that in “29(SP
mode 29)”.
* If the Setting Number is confi gured to be “31” Normal SP (factory setting), the static pressure
is 150Pa.
