How do I use the Sleep Mode Auto function?

Press the Sleep Mode Auto button to set the time you want the unit to turn off automatically, programmable in one-hour increments by pressing the button 1 to 7 times. In Cooling Mode, the temperature will automatically rise by 1°C over the next 30 minutes and by 2°C in 1 hour for comfortable sleeping, and the unit will operate at low fan speed. To cancel Sleep Mode, press the Sleep Mode Auto button several times until the star symbol disappears from the operation display. (Page 18)
