FEATURES AND FUNCTIONS

INVERTER

At the start of operation, a large power is used to bring the room quickly to the desired temperature. Afterwards, the unit automatically switches to a low power setting for economic and comfortable operation.

HORIZONTAL AIRFLOW: COOLING/ DOWNWARD AIRFLOW: HEATING

For cooling, use horizontal airflow so the cool air does not blow directly on the occupants in the room. For heating, use downward airfl ow to send powerful, warm air to the fl oor and create a comfortable environment.

ECONOMY OPERATION

Limits the maximum operation current, and performs operation with the power consumption suppressed. When economy operation mode is operated, the room temperature will be little higher than the set-tempunder cooling mode and lower thanset-tempunder heating mode. Therefore, the economy mode is able to save more energy than other normal mode.

AUTO CHANGEOVER

The operation mode (cooling, dry, heating) is switched automatically to maintain the set temperature, and the temperature is kept constant at all times.

OMNI-DIRECTIONALAIR FLOW (SWING OPERATION)

Three-dimensionalcontrol over air direction swing is possible through dual use of both an UP/DOWN air direction swing and RIGHT/LEFT air direction swing. Since UP/DOWN air direction fl aps operate automatically according to the operating mode of the unit, it is possible to set air direction based on the operating mode.

REMOVABLE INTAKE GRILLE

The indoor unit’s INTAKE GRILLE can be removed for easy cleaning and maintenance.

MINIMUM HEAT OPERATION

The room temperature can be maintained at 50°F so as to prevent the room temperature from falling too far.

PROGRAM TIMER

The program timer allows you to integrate OFF timer and ON timer operations in a single sequence. The sequence can involve one transition from OFF timer to ON timer, or from ON timer to OFF timer, within a twenty-fourhour period.

MILDEW-RESISTANTFILTER

The AIR FILTER has been treated to resist mildew growth, thus allowing cleaner use and easier care.

SUPER QUIET OPERATION

When the FAN button is used to select QUIET, the unit begins super-quietoperation; the indoor unit’s airflow is reduced to produce quieter operation.

SLEEP TIMER

When the SLEEP button is pressed during Heating mode, the air conditioner’s thermostat setting is gradually lowered during the period of operation; during cooling mode, the thermostat setting is gradually raised during the period of operation. When the set time is reached, the unit automatically turns off.

WIRELESS REMOTE CONTROLLER

The Wireless Remote Controller allows convenient control of air conditioner operation.

WIRED REMOTE CONTROLLER (OPTION)

The optional wired remote controller (model No.: UTY-RNBLU)can be used.

When you use remote controller, there are following different points as compared with using wireless remote controller.

[The additional functions for wired ones]

Weekly timer

Temperature set back timer

[The restricted functions for wired ones]

MAINTENANCE (FILTER RESET)

THERMO SENSOR

And you cannot use both wired and wireless remote controller simultaneously. (Only one kind can be selected)

OPERATION

To Stop Operation

Press the START/STOP button (Fig. 6 b8).

The OPERATION Indicator Lamp (green) (Fig.3 a5) will go out.

About AUTO CHANGEOVER Operation

AUTO: ● When AUTO CHANGEOVER operation fi rst 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.

If the differance between thermostat setting and actual room temperature is more than +4 °F → Cooling or dry operation

If the difference between thermostat setting and actual room temperature is within ±4 °F → Monitor operation

If the difference between thermostat setting and actual room temperature is more than –4°F → Heating operation

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 conditioner will once again select the appropriate operation (Heating, Cooling) to adjust the temperature to the value set in the thermostat.

(The monitor operation range is ±4 °F 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).

About Mode Operation

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 (green) (Fig.3 a5) 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 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.

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.
