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.

TEST RUN
8.1. Test run using Outdoor unit (PCB)
• Refer to the Installation Manual for the outdoor unit if the PCB for the outdoor unit is to
be used for the test run.
8.2. Test run using remote controller
• Refer to the Installation Manual for the remote controller to perform the test run using
the remote controller.
• When the air conditioner is being test run, the OPERATION and TIMER fl ash slowly at
the same time.
For details, please refer to the Manual of “IR Receiver Unit” or “Wired Remote Controller”.
