• Press RESET gently using a thin instrument.

If the RESET button is not pressed, the remote controller may not operate correctly.

SELECTING OPERATION MODES

AUTO mode (Auto change over)
The unit selects the operation mode according to the difference between the room temperature and the set temperature. During AUTO mode, the unit changes mode (COOL*-+HEAT) when the room temperature is about 20C away from the set temperature for more than 15 minutes.

Note:
Auto Mode is not recommended if this indoor unit is connected to a MXZ type outdoor unit. When several indoor units are operated simultaneously the unit may not be able to switch operation mode between COOL and HEAT. In this case, the indoor unit becomes standby mode (Refer to table of Operation indicator lamp).

COOL mode
Enjoy cool air at your desired temperature.

Note:
Do not operate COOL mode at very low outside temperatures (less than-IOOC). Water condensed in the unit may drip and wet or damage furniture, etc.

Note:
Multi system operation
Two or more indoor units can be operated by one outdoor unit. When several indoor units are operated simultaneously, cooling/dry/fan and heating operations cannot be done at the same time. When COOLIDRY/FAN is selected with one unit and HEAT with another or vice versa, the unit selected last goes into standby mode.
The operation indicator lamp shows the operation state of the unit.
For VGK type

FAN SPEED AND AIRFLOW DIRECTION ADJUSTMENT

I-SAVE OPERATION

Note:
Example of use.

1. Low energy mode
   Set the temperature 20C to 30C warmer in COOL and cooler in HEAT mode. This setting is suitable for unoccupied room, and while you are sleeping.

2. Saving frequently used settings
   Save your preferred setting for COOL, ECONO COOL, HEAT mode and NIGHT MODE operation. This enables you to select your preferred setting with a single push of the button.

ECONO COOL OPERATION

Swing airflow (change of airflow) makes you feel cooler than stationary airflow.

The set temperature and the airflow direction are automatically changed by the microprocessor. It is possible to perform cooling operation with keeping comfort. As a result energy can be saved.

NIGHT MODE OPERATION

NIGHT MODE operation changes the brightness of the operation indicator, disables the beep sound and limits the noise level of the outdoor unit.

Note:

• The cooling/heating capacity may drop.
• Noise level of the outdoor unit may not change after start-up of the unit, during the protection operation, or depending on other operating conditions.
• The fan speed of the indoor unit will not change.
• The operation indicator lamp will be hard to be seen in a bright room.
• Noise level of the outdoor unit will not decrease during Multi system operation.

AIR PURIFYING OPERATION

In the AIR PURIFYING operation, the indoor unit built-in device reduces airborne fungi, viruses, mold, and allergens.

Note:

• Never touch the air purifying device during operation. Although the air purifying device is safety-conscious design, touching this device could be the cause of trouble as this device discharge high voltage electricity.
• A “hissing” sound may be heard during the air purifying operation. This sound is produced when plasma is being discharged. This is not a malfunction.
• Air purifying lamp does not turn on if the front panel is not closed completely.

TIMER OPERATION (ON/OFF TIMER)

WEEKLY TIMER OPERATION

EMERGENCY OPERATION

When the remote controller cannot be used…
Emergency operation can be activated by pressing the emergency operation switch (E.O. SW) on the indoor unit

Each time the E.O. SW is pressed, the operation changes in the following order:
