When using the wireless remote controller, point it towards the receiver on the indoor unit. If the remote controller is operated within approximately two minutes after power is supplied to the indoor unit, the indoor unit may beep twice as the unit is performing the initial automatic check.

The indoor unit beeps to confirm that the signal transmitted from the remote controller has been received. Signals can be received up to approximately 7 meters in a direct line from the indoor unit in an area 45° to the left and right of the unit. However, illumination such as fluorescent lights and strong light can affect the ability of the indoor unit to receive signals.

If the operation lamp near the receiver on the indoor unit is flashing, the unit needs to be inspected. Consult your dealer for service.

Handle the remote controller carefully! Do not drop the remote controller or subject it to strong shocks. In addition, do not get the remote controller wet or leave it in a location with high humidity.

To avoid misplacing the remote controller, install the holder included with the remote controller on a wall and be sure to always place the remote controller in the holder after use.

Automatic operation

According to a set temperature, cooling operation starts if the room temperature is too hot and heating operation starts if the room temperature is too cold.

During automatic operation, if the room temperature changes and remains 2 °C or more above the set temperature for 15 minutes, the air conditioner switches to cool mode. In the same way, if the room temperature remains 2 °C or more below the set temperature for 15 minutes, the air conditioner switches to heat mode.

Cool mode			15 minutes (switches
			from heating to cooling)
							Set temperature +2°C
							Set temperature

Set temperature -2°C

15 minutes (switches from cooling to heating )

Because the room temperature is automatically adjusted in order to maintain a fixed effective temperature, cooling operation is performed a few degrees warmer and heating operation is performed a few degrees cooler than the set room temperature once the temperature is reached (automatic energy-saving operation).

5.3. Temperature setting

To decrease the room temperature:

Press button 3 to set the desired temperature. The selected temperature is displayed 3.

To increase the room temperature:

Press button 3 to set the desired temperature.

The selected temperature is displayed 3.

• Available temperature ranges are as follows:

Cooling/Drying:	19 - 30 °C
Heating:	17 - 28 °C
Automatic:	19 - 28 °C

•The display flashes either 8 °C - 39 °C to inform you if the room temperature is lower or higher than the displayed temperature.

5.4. Fan speed setting

Press the Fan Speed button 5 as many times as necessary while the system is running.

•Each press changes the force. The currently selected speed is shown at 5.

•The change sequence, and the available settings, are as follows.

FAN SPEED			Display
3-speed	Speed 1	Speed 2	Speed 3	Auto

Auto

Note:

The number of available fan speeds depends on the type of unit connected. Note also that some units do not provide an “Auto” setting.

In the following cases, the actual fan speed generated by the unit will differ from the speed shown the remote controller display.

1.While the display is showing “STAND BY” or “DEFROST”.

2.When the temperature of the heat exchanger is low in the heat mode. (e.g. immediately after heat operation starts)

3.In HEAT mode, when room temperature is higher than the temperature setting.

4.When the unit is in DRY mode.
