Part 2 Functions & Controls

1.1 Hot start

• When heating is started, the indoor fan is stopped or very slow to prevent the cold air carry out

• When the temp. of heat exchanger reach 30 °C(model by model), indoor fan is started.

4.2 Self-diagnosis Function

• The air conditioner installed can self-diagnosed its error status and then transmits the result to the central control.

Therefore, a rapid countermeasure against failure of the air conditioner allows easy management and increases the

usage life of air conditioner.

• Refer to trouble shooting guide.

4.3 Soft dry operation

• When the dehumidification operation input by the remote control is received, the intake air temperature is detected and

the setting temp is automatically set according to the intake air temperature.

• While compressor off, the indoor fan repeats low airflow speed and stop.

• While the intake air temp is between compressor on temp. and compressor off temp., 10 minutes dehumidification

operation and 4 minutes compressor off repeat.

Compressor ON Temp. ‘ Setting Temp+0.5 °C

Compressor OFF Temp. ‘ Setting Temp-0.5 °C

• In 10-minute dehumidification operation, the indoor fan operates with the low airflow speed.
