ADJUSTING THE FAN SPEED
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.

What does the SLEEP mode mean?
In this mode, the air conditioner will cool or 
heat the room to the set temperature, and 
then the thermostat will make the unit pause. 
After about 1 hour, the air conditioner will 
automatically reset the set temperature as 
follows (also refer to graphs).
OPERATING MODE SET TEMPERATURE CHANGE
Heating Lowered by 1 °C
Cooling and Dehumidifying  Raised by 1 °C
When the room temperature reaches the new 
set value, the thermostat will cause the unit to 
pause. After about 1 hour the temperature will be 
raised by 1 °C in cooling, or lowered by 1 °C in 
heating. This enables you to save energy without 
sacrificing your comfort.
