OPERATION

Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).

To Stop Operation

Press the START/STOP button.

The OPERATION indicator lamp (green) will go out.

  When AUTO (automatic changeover) is selected, the air conditioner selects the appropriate operation mode (cooling 

or heating) according to your room’s present temperature.

  When AUTO (automatic changeover) operation first selected, the fan will operate at low speed for about a few minute, 

during which time the indoor unit detects the room conditions and selects the proper operation mode.

  Room temperature is higher than the defined temperature in temperature 

setting → Cooling mode or dry mode

  Room temperature is close to the defined temperature in temperature 

setting → Determined by outdoor temperature

  Room temperature is lower than the defined temperature in temperature 

setting → Heating mode 

  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 temperature subsequently changes, the air conditioner will once again select the appropriate operation 

(heating, cooling) to adjust the temperature to the value set in the thermostat.

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

DRY, FAN).

  When AUTO (automatic changeover) operation first selected, the fan will oper-

ate at very low speed for about a few minutes, during which time the indoor 

unit detects the room conditions and selects the proper mode.

  Room temperature is higher than the defined temperature in temperature set-

ting → Cooling mode or dry mode

  Room temperature is close to or lower than the defined temperature in tem-

perature setting → Monitor operation

  When the indoor unit has adjusted your room’s temperature to near the temperature setting, it will begin monitor opera-

tion. In the monitor operation mode, the fan will operate at low speed. If the room temperature subsequently changes, 

the indoor unit will once again select the appropriate operation (cooling) to adjust the temperature to the value set in 

the temperature setting.

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

FAN).

Mode operation

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 

setting that is lower than the current 

room temperature. The cooling and dry 

modes will not operate if the thermo-

stat is set higher than the actual room 

temperature (in cooling mode, the fan 

alone will operate).

During fan mode:

You can not use the unit to heat and 

cool your room.

HEAT*:

 

  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 beginning 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 heat operation will be interrupted.

 

  After the start of heating operation, it takes sometime before the room gets 

warmer.

  COOL:

 

  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 se-

lected.

  FAN:

 

  Use to circulate the air throughout your room.
