About AUTO CHANGEOVER Operation

AUTO:

 

 When AUTO CHANGEOVER is selected, the air conditioner selects the 

appropriate operation mode (Cooling or Heating) according to your room’s 
present temperature.

 

  When AUTO CHANGEOVER operation 

fi

 rst selected, the fan will operate 

at low speed for about a few minute, during which time the indoor unit de-
tects the room conditions and selects the proper operation mode.

 

  If the difference between thermostat setting and actual room temperature 

is more than +2 °C

  If the difference between thermostat setting and actual room temperature 

is within ±2 °C

 Determined by outdoor temperature

 

  If the difference between thermostat setting and actual room temperature 

is more than –2 °C

 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 op-
eration mode, the fan will operate at low speed. If the room temperature 
subsequently changes, the air conditioner will once again select the ap-
propriate 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).

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 se-
lected fan setting. This period of time is provided to allow the indoor unit 
to warm up before beginning full operation.

 

  When the outdoor 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. Dur-
ing Automatic Defrosting operation, the OPERATION Indicator Lamp will 

fl

 ash, and the heat operation will be interrupted.

 

 After the start of heating operation, it takes some time before the room 

gets warmer.

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 setting 
that is higher than the current room tem-
perature. The Heating mode will not oper-
ate 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 tem-
perature. The Cooling and Dry modes will 
not operate if the thermostat is set higher 
than the actual room temperature (in Cool-
ing mode, the fan alone will operate).

During Fan mode:

You can not use the unit to heat and cool 
your room.
