Function Setting - Fujitsu AIRSTAGE ARUM24TLAV 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.
(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 pip-
ing 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.
