About AUTO CHANGEOVER Operation

AUTO: ● When AUTO CHANGEOVER operation first selected, the fan will oper- ate at very low speed for about one minute, during which time the unit detects the room conditions and selects the proper operating mode.

If the difference between the thermostat setting and actual room tem- perature is more than +4 °F → Cooling or dry operation

If the difference between the thermostat setting and actual room tem- perature is +4 °F or less → Monitor operation

●When the thermostat setting of air conditioner has been adjusted to near the room temperature or the room temperature becomes lower than the thermostat setting, it will begin monitor operation. In the monitor operation mode, the fan will operate at low speed. If the room temperature subsequently changes, the air conditioner will once again select the appropriate operation (Cooling) to adjust the temperature to the value set in the thermostat.

(The monitor operation range is in the temperature of +4 °F or less relative to the thermostat setting.)

●If the mode automatically selected by the unit is not what you wish, select one of the mode operation (COOL, DRY, FAN).

About Mode Operation

Cooling: ● Use to cool your room.

Dry: ● Use for gently cooling while dehumidifying your room.

●You cannot heat the room during Dry mode.

●During Dry mode, the unit will operate at low speed; in order to adjust room humidity, the indoor unit’s fan may stop from time to time. Also, the fan may operate at very low speed when adjusting room humidity.

●The fan speed cannot be changed manually when Dry mode has been selected.

Fan: ● Use to circulate the air throughout your room.

During Cooling/Dry mode:

Set the thermostat to a temperature set- ting that is lower than the current room temperature.The Cooling and Dry modes will not operate if the thermostat is set higher than the actual room temperature (in Cooling mode, the fan alone will oper- ate).

During Fan mode:

You can not use the unit to cool your room.
