About AUTO CHANGEOVER Operation
● When AUTO CHANGEOVER operation fi rst selected, the fan will operate
AUTO:
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 temperature
is more than +4 °F
If the difference between thermostat setting and actual room temperature
is within ±4 °F
If the difference between thermostat setting and actual room temperature
is more than –4 °F
● 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.
(The monitor operation range is ±4 °F relative to the thermostat setting.)
● 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 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 Indicator Lamp (green)
(Fig.3 a5) 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.
● Use for gently cooling while dehumidifying your room.
Dry:
● 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.
● Use to circulate the air throughout your room.
