About Mode Operation
Heating: G Use to warm your room.
G 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.
G 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, and the heat operation
will be interrupted.
G After the start of heating operation, it takes sometime before the room
gets warmer.
Cooling: G Use to cool your room.
G Use for gently cooling while dehumidifying your room.
Dry:
G You cannot heat the room during Dry mode.
G 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.
G The fan speed cannot be changed manually when Dry mode has been
selected.
G Use to circulate the air throughout your room.

G During the Drying mode operation, the FAN setting
should be switched to LOW for a gently cooling effect
during which the fan may temporarily stop rotating.
G 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 very
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. (The moni-
tor operation range is ±4 °F relative to the thermostat
setting.)
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 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.
