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 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, 66 °F - 86 °F
Heating: 17 - 28 °C, 63 °F - 82 °F
Automatic: 19 - 28 °C, 66 °F - 82 °F
• The display flashes either 8 °C - 39 °C, 46 °F - 102 °F to inform

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.
5.5. Airflow up/down direction setting
<To change the airflow up/down direction>
With the unit running, press the Airflow up/down button 6 as
necessary.

unit.
* 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 operation mode change to take effect).
3. In heat mode, when room temperature is higher than the temperature
setting.

• Stop the unit operation, hold the lever of the louver
airflow vanes, and adjust to the desired direction.
* Do not set to the inside direction when the unit is in
the cooling or drying mode because there is a risk
of condensation and water dripping.
Caution:
To prevent falls, maintain a stable footing when operating the unit.
