6. Natural Wind by CHAOS logic
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 has successfully created such a feeling of freshness and
serenity by analyzing the frequency of natural wind.

Through analysis in its chaos simulator, Goldstar has successfully created such a feeling of freshness and

Generally natural wind has the following character (frequency-Magnitude), for example dark vally, sea, mountain

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.

ƒU
During heating operation, if piping temperatures falls below 26°C fan stops.

9. Deice Control
ƒU
Deicing operation is controlled by timer and sensing the outdoor piping temperature.
ƒU
The first deicing starts only when the outdoor pipe temperature falls below -6

after 60 minutes passed from
starting of heating operation and more than 10 minute operation of compressor.
ƒU
Deicing ends after 12 minutes passed from starting of deice operation or when the outdoor pipe temperature

10. Soft Dry Operation.
• During Soft Dry Operation, the compressor ON temperature is the setting temperature plus 1
¡
, the compres-
sor OFF temperature is the setting temperature minus 0.5
¡
• When the room temperature rises over the compressor ON temperature, the operation mode is switched to the
cooling mode.
• When the room temperature falls between the compressor ON temperature and OFF temperature, the opera-
tion mode is switched to the Soft Dry Operation.
In this temperature range, 10min. Dry Operation, 5.5min operation OFF, 1.5min. only fan operation repeat. Dur-
ing 10min Dry operation, even if the room temperature falls below compressor OFF temperature, 10min(MAX)
Compressor ON from starting of Dry operation which includes 4 min(MAX). Compressor ON operation below
the comperssor OFF temperature.
