AUTOMATIC
Simply set the FAN SPEED selector to the
position . A microcomputer automatically controls
the fan speed when the AUTO mode is selected.
When the air conditioner starts operating, the
difference between the room temperature
and the set temperature is detected by the
microcomputer which then automatically switches
the fan speed to the most suitable level.
NOTE
In FAN Only mode the fan speed is adjusted
automatically as in cooling mode.

automatically reset the set temperature as
follows (also refer to graphs).
OPERATING MODE SET TEMPERATURE CHANGE
