Heating operation
●
When the indoor unit has adjusted your room’s temperature to near
the thermostat setting, it will begin monitor operation. In the monitor
operation mode, the fan will operate at low speed. If the room tem-
perature subsequently changes, the indoor unit will once again select
the appropriate operation (Heating, Cooling) to adjust the tempera-
ture to the value set in the thermostat.

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 selected 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 out-
door 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 (Fig. 3
5
) will fl ash, and the heat opera-
tion 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 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.

ting that is higher than the present room
temperature. The Heating mode will not
operate if the thermostat is set lower
than the actual room temperature.
