INDOOR UNIT (Setting by remote controller)12-2.
The function settings of the control of the indoor unit can be changed by this procedure according •
to the installation conditions. Incorrect settings can cause the indoor unit malfunction.
After the power is turned on, perform the “FUNCTION SETTING” according to the installation •
conditions using the remote controller.
The settings may be selected between the following two: Function Number or Setting Value. •
Settings will not be changed if invalid numbers or setting values are selected. •
PREPARATION
Turn on the power. •
* By turning on the power indoor units, 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.
