Automatic operation

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

During automatic operation, if the room temperature changes and re- mains 2 °C, 4 °F or more above the set temperature for 15 minutes, the air conditioner switches to cooling mode. In the same way, if the room temperature remains 2 °C, 4 °F or more below the set temperature for 15 minutes, the air conditioner switches to heating mode.

Cooling mode

15 minutes (switches from heating to cooling)

Set temperature +2°C, +4°F

Set temperature

Set temperature -2°C, -4°F

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

sTo decrease the room temperature:

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

sTo increase the room temperature:

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

Available temperature ranges are as follows:

Cooling/Drying:

19 - 30 °C, 67 - 87 °F

Heating:

17 - 28 °C, 63 - 83 °F

Automatic:

19 - 28 °C, 67 - 83 °F

The display flashes either 8 °C - 39 °C, 46 °F - 102 °F 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 .

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

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 heating mode. (e.g. immediately after heating operation starts)

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

4.When the unit is in DRY mode.

5.5. Airflow direction setting

<To Change the Airflow’s Up/Down Direction>

With the unit running, press the Airflow Up/Down button 6as necessary.

Each press changes the direction. The current direction is shown at §.

*Some models do not support directional settings.

Note:

Available directions depend on the type of unit connected. Note also that some units do not provide an “Auto” setting.

In the following cases, the actual air direction will differ from the direction indicated on the remote controller display.

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

2.Immediately after starting heater mode (while the system is waiting for the mode change to take effect).

3.In heat mode, when room temperature is higher than the temperature set- ting.
