OPERATING TIPS
Mode operation: AUTO
About Mode Operation
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 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 ope-
rate).
During Fan mode:
You can not use the unit to heat and cool
your room.
* Heating:
L
Use to warm your room.
L
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.
L
When the outdoor temperature is very low, frost may form on the outdoor
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.
L
After the start of heating operation, it takes sometime before the room
gets warmer.
Cooling:
L
Use to cool your room.
Dry:
L
Use for gently cooling while dehumidifying your room.
L
You cannot heat the room during Dry mode.
L
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.
L
The fan speed cannot be changed manually when Dry mode has been
selected.
Fan:
L
Use to circulate the air throughout your room.
COOLING MODEL
L
When the room temperature is 2 °C higher than the set
temperature, the mode will switch between Cooling and
Drying.
L
During the Drying mode operation, the fan will operate at a
low speed for a gently cooling effect during which the fan
may temporarily stop rotating.
L
When the room temperature is near the thermostat set-
ting, the air conditioner will begin monitor operation. In the
monitor operation mode, the fan will operate at a low speed.
If the room temperature subsequently changes, the air
conditioner will once again select the appropriate operation
(Heating or Cooling) to adjust the temperature to the value
set in the thermostat.
L
If the mode automatically selected by the unit is not what
you wish, select one of the mode operation (HEAT, COOL,
DRY, FAN).
