AUTO CHANGEOVER OPERATION
HEAT & COOL MODEL (Reverse cycle)
• When AUTO CHANGEOVER operation is selected, the air conditioner selects the appropriate operation mode (Cooling or
Heating) in response to your room's temperature.
• When AUTO CHANGEOVER operation first selected, the fan will operate at very low speed for about one minute, during
which time the unit detects the room conditions and selects the proper operating mode.
• When the air conditioner 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 temperature subsequently changes, the air condi-
tioner will once again select the appropriate operation (Heating, Cooling) to adjust the temperature to the value set in the ther-
mostat. (The monitor operation range is ±2°C 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).
1.3.6
HEATING OPERATION (REVERSE CYCLE)
• 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 selected fan setting. This period of time is provided to allow the indoor unit to warm up before begin full opera-
tion.
• 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 (red) will flash, and the heat operation will be interrupted.
1.3.7
COOLING OPERATION
• Use to cool your room.
1.3.8
DRY OPERATION
• Use for gently cooling while dehumifdifying your room.
• 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 detecting room humidity.
• Then fan speed cannot be changed manually when Dry
mode has been selected.
During Heating mode :
Set the thermostat to a temperature setting 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 setting 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 operate).
During Fan mode :
You can not use the unit to heat and cool your room.
