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 differance between thermostat setting and actual room tempera- ture is more than +4 °F → Cooling or dry operation

If the difference between thermostat setting and actual room tempera- ture is within ±4 °F → Monitor operation

If the difference between thermostat setting and actual room tempera- ture is more than –4 °F → Heating operation

●When the air conditioner has adjusted your room’s temperature to near the thermostat setting, it will begin monitor operation. In the monitor operation mode, the fan will operate at low speed. If the room tem- perature subsequently changes, the air conditioner will once again select the appropriate operation (Heating, Cooling) to adjust the tem- perature to the value set in the thermostat.

(The monitor operation range is ±4 °F relative to the thermostat set- ting.)

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

About Mode Operation

Heating: ● Use to warm your room.

●When Heating mode is selected, the air conditioner will operate at very low fan speed for about 3 to 5 minutes, after which it will switch to the selected fan setting. This period of time is provided to allow the indoor unit to warm up before begin full operation.

●When the room temperature is very low, frost may form on the outside unit, and its performance may be reduced. In order to remove such frost, the unit will automatically enter the defrost cycle from time to time. During Automatic Defrosting operation, the OPERATION Indica- tor Lamp (red) (Fig. 3 5)will flash, and the heat operation will be inter- rupted.

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 Heating mode:

Set the thermostat to a temperature set- ting that is higher than the current room temperature. The Heating mode will not operate if the thermostat is set lower than the actual room temperature.

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 heat and cool your room.
