About AUTO CHANGEOVER Operation
AUTO:
● When AUTO CHANGEOVER operation fi rst selected, the fan will operate at very low speed for about a few minutes, during
which time the indoor unit detects the room conditions and selects the proper operation mode.
If the difference between temperature setting and actual room temperature is more than +4 °F (+2 °C)  Cooling or dry opera-
tion
If the difference between temperature setting and actual room temperature is within ±4 °F (±2 °C)  Determined by outdoor tem-
perature
If the difference between temperature setting and actual room temperature is more than -4 °F (-2 °C)  Heating operation
● When the indoor unit has adjusted your room's temperature to near the temperature 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 indoor unit will
once again select the appropriate operation (Heating, Cooling) to adjust the temperature to the value set in the temperature.
● If the mode automatically selected by the indoor 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 indoor unit 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 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 air conditioner will automatically enter the defrost cycle from time to
time. During 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 indoor unit will operate at low speed; in order to ad-
just 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.

Note for timer settings:
Any interruption of the power supply, such as a blackout or cutting off of a circuit breaker, makes
the set internal clock go wrong.
In such a case, the TIMER indicator on the indoor unit blinks, and you need to readjust the
setting.
