About Mode Operation
AUTO:
• Depending on the room temperature at the time operation begins, the operating
mode will be switched automatically as shown in the accompanying table.
Also, depending on the operating mode, the room temperature setting will cause
the "standard" temperature to be set as shown.
Example: When set to "normal"

The operating mode and standard thermostat settings are selected automatically
when operation begins.
• When automatic operation is initiated, the fan will run at very low speed for about
one minute while the unit detects and selects the proper operating mode.
• Once the operating mode has been set, the mode will not change even if the
room temperature changes.
• If the START/STOP button is pressed to recommence operation within two hours
after stopping automatic operation, the unit will begin operating from the same
mode as before.
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 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.
• The fan speed cannot be changed manually when Dry mode has been selected.
During Cooling/Dry mode:
Set the thermostat to a temperature setting
that is lower than the current room tempera¬
ture. 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:
• Fan operation begins when room tem¬
perature in the vicinity of the air condi¬
tioner rises above the set thermostat
temperature; when the temperature
drops, fan operation stops.
• If the air emitted feels too cool, raise
the thermostat setting.
Fan:
• Use to circulate warm air from ceiling area throughout room when using space
heaters.
