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. (Set
IU AD, REF AD SW to 0)
• 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.

notifi cation. If the notifi cation is too
early, change to setting 01. If the
notifi cation is too late, change to
setting 02.
Enable or disable the fi lter indicator.
Setting 02 is for use with a central
remote controller.
Adjust the cool air trigger tempera-
ture. To lower the trigger tempera-
ture, use setting 01. To raise the
trigger temperature, use setting 02.
Adjust the heat air trigger tempera-
ture. To lower the trigger tempera-
ture 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.
* Auto restart is an emergency func-
tion such as for power failure etc.
Do not start and stop the indoor
unit by this function in normal
operation.
Be sure to operate by the control
unit, converter or external input
device.
Restrain the cold airfl ow with making
the airfl ow lower when starting heat-
ing 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 re-
frigerant 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 controller is restricted.
Change the target for reporting
errors. Errors can either be reported
in all locations, or only on the central
remote controller.
When set to 01, the fan stops when
the thermostat is off in cooling
operation. Connection of the wired
remote controller (2-wire type
or 3-wire type) and switching its
thermistor are necessary.
