How The Air Conditioner Works

Operation Tips
The following events may occur during normal operation.
1. Protection of the air conditioner.
Compressor protection
The compressor can't restart for 3 minutes after it stops. Anti-cold air (Cooling and heating models only)
•
The unit is designed not to blow cold air on HEAT mode, when the indoor heat exchanger is in one of the
•
following three situations and the set temperature has not been reached.
A) When heating has just starting.
B) Defrosting.
C) Low temperature heating.
The indoor or outdoor fan stop running when defrosting (Cooling and heating models only). Defrosting
•
(Cooling and heating models only)
Frost may be generated on the outdoor unit during heat cycle when outdoor temperature is low and humidity
•
is high resulting in lower heating efficiency of the air conditioner.
During this condition air conditioner will stop heating operation and start defrosting automatically.
•
The time to defrost may vary from 4 to 10 minutes according to the outdoor temperature and the amount of
•
frost build-up on the outdoor unit.
AUTO operation
When you set the air conditioner in AUTO mode, it will
•
automatically select cooling, heating (cooling/heating
models only), or fan only operation depending on what
temperature you have selected and the room temperature.
The air conditioner will control room temperature
automatically round the temperature point set by you.
If the AUTO mode is uncomfortable, you can select desired
•
conditions manually.
SLEEP operation
When you push SLEEP button on remote controller during
cooling, heating(cooling only type without), or AUTO operation ,
the air conditioner will automatically increase (cooling) or
decrease (heating) 1° C per hour for the first 2 hours, then hold
steady for the next 5 hours, after that it will switch off. This
characteristic maintains both energy saving and comfort in night
operation.
DRYING operation
The fan speed will be automatically controlled under dry
•
operation.
During the dry operation, if the room temperature is lower
•
than 10°C, the compressor stops operation and restarts until
the room temperature is above 12° C.
