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, Goldstar had successfully created such a feeling of freshness and
serenity 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 according
to the CHAOS logic.
