Function Button and Indicator Light Operation
Cooling Mode. In Cool mode the unit attempts to bring the room air temperature down to the set
temperature. The fan speed and temperature are adjusted in Cool mode.
Note: The room temperature must be higher than the set temperature in order for the cooling
mode to start.
Dry Mode (Dehumidify). Press the ON/OFF button to start the cooling unit. Press the Mode button to
choose Dry. In Dry mode, the fan speed is fixed to Low.
• In Dry mode, air is not exhausted to the outside.
Fan Mode. When in Fan mode, air is circulated with no cooling. Low, Medium, and High fan speed can
be selected. Indicator bars on the display show the fan speed.
Auto Mode. The cooling unit will automatically choose the Cool, Dry, or Fan mode to ensure the
indoor constant temperature efficiency based on the set temperature you have selected.
Sleep Mode. Sleep mode is an energy saving mode. The Sleep mode temperature must be preset. When
Sleep mode starts (in Cool mode), the temperature increases by two degrees after one hour and four
degrees after two hours. After two hours the cooling unit will run at the preset temperature. In Fan or
Auto mode, the temperature is not changed during Sleep mode because cooling is not occurring.

Auto ON: With the cooling unit powered on but in standby mode (no mode selected), press the Timer
button to start the timer function. Press the up or down arrow buttons to select the number of hours
before the cooling unit automatically starts running in Cool mode.
Temperature Control. The default display is the set temperature. In Cool mode, the set temperature is
adjusted when the up and down buttons are pressed.

• Press the up arrow button to increase the set temperature and the down arrow button to lower the
set temperature.
