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

Temperature
88°F or above
82°F-88°F

Below 72°F
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.
However, during the monitor operation mode, if the room temperature changes to below 72°F, the mode will
automatically switch to Heat, and when it rises above 75°F the mode will automatically switch to Dry.
¶ When in the monitor mode, the fan will operate very slowly.
¶ 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.
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 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 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.
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 detecting room humidity.
¶ The fan speed cannot be changed manually when Dry mode has been selected.
¶ Use to circulate the air throughout your room.
