7.1. Setting the address
Use an insulated screwdriver to set the dip switches.
• Open the cover referring to the figure below. Close and fix the cover after addressing
setting.
(1) Loosen the screw.
(2) Slide the cover and open it.
7.1.1 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.
7.1.2 Refrigerant circuit address
• Rotary switch (IU AD × 1)...Factory setting "0"
• Rotary switch (IU 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 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".

Do not set the indoor unit address (IU AD SW) at 64 to 99.
It may result in failure.
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. Function setting
• 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.
• Refer to "7.1. Setting the address" for indoor unit address and refrigerant circuit address
settings.
• Turn the power of the indoor unit ON before starting the setting.
* Turning on the power to the indoor units initializes EEV, so make sure the piping air tight
test and vacuuming have been conducted before turning on the power.
* Also check again to make sure no wiring mistakes were made before turning on the
power.

Adjust the filter cleaning interval
notification. If the notification
is too early, change to setting
01. If the notification is too late,
change to setting 02.
Enable or disable the filter indi-
cator. Setting 02 is for use with a
central remote controller.
Regulate the airflow according
to the needs of the installation
location. When set to 01, the air
flow will be stronger. (Cassette
type only)
Adjust the vertical airflow direc-
tion. All airflow direction louvers
are adjusted together.
Adjust the cool air trigger
temperature. To lower the trigger
temperature, use setting 01. To
raise the trigger temperature,
use setting 02.
Adjust the heat air trigger
temperature. To lower the trigger
temperature by 6 degrees C, use
setting 01. To lower the trigger
temperature by 4 degrees C, use
setting 02. To raise the trigger
temperature, use setting 03.
Enable or disable automatic
system restart after a power
outage.
Restrain the cold airflow with
making the airflow lower when
starting heating operation. To
correspond to the ventilation,
set to 01.
Allow an external controller to
start or stop the system, or to
perform an emergency stop.
* If an emergency stop is
performed from an external
controller, all refrigerant
systems will be disabled.
* If forced stop is set, indoor
unit stops by the input to the
external input terminals, and
Start/Stop by a remote control-
ler is restricted.
Change the target for reporting
errors. Errors can either be re-
ported in all locations, or only on
the central remote controller.
