4-3. Adjusting each function
The following section describes the operation of the switches for the OPERATION MODE, TEMPERATURE SETTING, FAN SPEED, AIR DIRECTION SETTING, HORIZONTAL BLOW, VENTILATION
SETTING and EXTERNAL TIMER SETTINGS.
If your air conditioner is not equipped with FAN SPEED, AIR DIRECTION SETTING, HORIZONTAL
BLOW, VENTILATION SETTING and EXTERNAL TIMER SETTINGS or a PROGRAM TIMER (sold
separately), the “NOT AVAILABLE” indicator will blink when the switches for these functions are
operated and the operation will not be performed.
However, “NOT AVAILABLE” does not appear on the COLLECTIVE OPERATION SETTING
SCREEN.
If “CENTRALLY CONTROLLED” blinks when the each switch is operated, the message indicates
that the operation is prohibited by the master controller.
All of the blinking items in the COLLECTIVE OPERATION SETTING SCREEN indicate items that
can be adjusted. After the items are adjusted they will stop blinking but will remain lit and those
adjustments will be applied to all groups.
