Part 2 Functions & Controls
3.1 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.
3.2 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.
3.3 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-min dehumidification opera-
tion and 4-min compressor off repeat.
Compressor ON Temp.
➔
Setting Temp+0.5°C
Compressor OFF Temp.
➔
Setting Temp-0.5°C
• In 10-min dehumidification operation, the indoor fan operates with the low airflow speed.
