14.1.5 Automatic Operation

This mode can be set using remote control and the operation is decided by remote control setting temperature,
remote control operation mode and indoor intake air temperature.

During operation mode judgment, indoor fan motor (with speed of Lo-) is running for 30 seconds to detect the
indoor intake air temperature.

Every 10 minutes, the indoor temperature is judged.

For the 1st judgment
If indoor intake temperature - remote control setting temperature ≥ 2°C, COOL mode is decided.
o
If -2°C ≤ indoor intake temperature - remote control setting temperature < 2°C, DRY mode is decided.
o
If indoor intake temperature - remote control setting temperature < -2°C, HEAT mode is decided.
o

For the 2nd judgment onwards
If indoor intake temperature - remote control setting temperature ≥ 3°C, if previous operate in DRY mode,
o
then continue in DRY mode. Otherwise COOL mode is decided.
If -2°C ≤ indoor intake temperature - remote control setting temperature < 3°C, maintain with previous mode.
o
If indoor intake temperature - remote control setting temperature < -2°C, HEAT mode is decided.

14.1.6 iAUTO-X Operation

iAUTO-X operation can be set using remote control.

This operation is applied to faster cool down time of the room and comfort feel by thermal shift and fan speed
control.

Thermal control
The internal setting temperature will shift 1°C lower than remote control setting temperature for maximum 4
o
hours to provide extra cool and better comfort.
After max. 4 hours, the remote control setting temperature will shift according to activity detection as below;
o

Fan speed control
Fan speed selection is prohibited. Fan speed display at remote control is fixed at AUTO.
o
The internal fan speed will set to be SHi + iAUTO-X fan speed shift, it is slightly higher than SHi fan speed
o
initially for maximum 30 minutes to achieve the setting temperature quickly. Then it will shift between SHi ~
Lo fan speed depends on intake and setting temperature.

Vane control is follow remote control setting. Except for Auto horizontal vane, when room temperature more than
27°C, it will give a spot airflow (inner and outer vanes will be in a smaller distance). When room temperature cool
down, it will either fixed at step 3 or step 1 (Showering effect for better comfort after room temperature cooled
down) depends on the "intake - setting temperature".
14.1.7 Fan Operation

Fan operation is used to circulate air in the room.

During operation, indoor fan run continuously but outdoor fan and compressor stop.

Temperature setting is not applicable.
