There are common rules in the irregular changes amid the breeze of highlands and valleys, the sound of
streams, the songs of birds in the forest and brain waves of relaxation.

Mmm... the breath-taking and touchy feeling of wind from the deep mountains and dark valleys.

Through analysis in its chaos simulator, LG has successfully created such a feeling of freshness and sereni-
ty by analyzing the frequency of natural wind.

Generally natural wind has the following character (Frequency-Magnitude), for example dark valley, sea,
mountain wind.

So as to make a similar Natural wind function, Indoor fan speed is shifted to high from low or reversely in
according to the CHAOS logic.

The unit will operate according to the setting by the remote controller and the operation diagram is shown as
following.

• The indoor fan stops until the evaporator piping temperature will be reached at 28°C.(BY TEMPERATURE)
