Function Setting - Fujitsu Airstage ARUM24TLAV2 Installation Manual

7.4. 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 indica-
tor. Setting 02 is for use with a
central remote controller.
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 sys-
tem restart after a power outage.
Restrain the cold airflow with mak-
ing 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 controller is
restricted.
Change the target for reporting er-
rors. 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) and switching its thermistor
are necessary.
• Set this function when connecting
the VRF system to a ventilator,
economizer, humidifier, or other
external device.
• The connection terminal func-
tions can be changed depending
on the type of external device.
For details of the connection ter-
minal functions, see the Design
& Technical Manual.

Sets the control method for the
external heater being used. For
details of the control method, see
the Design & Technical Manual.
• Sets the temperature conditions

For a more detailed explana-
tion, see the Design & Technical
Manual.
Switch the setting method of
auto mode to single or dual
(cooling/heating).
For heat pump systems, it is
necessary to set the master
indoor unit (by wired remote
controller).
Choose the minimum temperature
between cooling and heating
settings (deadband) for Dual
setpoint auto mode (set in No. 68).
