Remark
When operate the refrigerator for the first time ,after connect the plug ,adjust the temperature to center position of each control and leave it for 24 hours for the effective cooling operation. After that ,adjust the temperature as you prefer . If you want to save the energy,do not adjust the temperature lower than the actual operating condition.

2.Introduction
FUNCTION OF ELECTRONIC CONTROL
2.1 FREEZER TEMPERATURE CONTROL
It actuates the compressor, FC fan motor ,and cooling system switch according to temperature variation in the freezer compartment. And atmosphere temperature by processing the input from, FC temperature sensor and adjustment of temperature control.
2.2 COMPRESSOR ROTATION SPEED CONTROL
According to changing inside temperature,the motor runs in the difference speed. In normal, the motor run in the low speed. (Energy saving & lower noise.)
When powerful cooling is required, motor run in rapid speed.

2.3 QUICK FREEZING FUNCTION
Press "QUICK FREEZING"button , and then quick function starts and LED sign comes on.
It actuates the compressor continuously for certain period regardless of compartment temperature, by processing the input from AT temperature sensor. (AT temperature : Atmosphere temperature)

※
When the green light is blinking after pressing the "QUICK FREEZING" button, the function of quick freezing
is waiting .The situation of refrigerator is processing as below:
a.The refrigerator is defrosting .
b.The compressor is stopped,because temperature of the freezing compartment reachs setting of temperature.
When the above situation is solved , quick- freeze will be started automatically,then the "QUICK FREEZING"
light bright is on.
2.4 FC DEFROSTING CONTROL
Cumulating the compressor running time of certain period or time after defrosting according to AT temperature,
FC defrosting cycle starts. (AT temperature : Atmosphere temperature)
Termination is detected by defrost sensor ,but maximum defrosting time is 60 minutes (Defrosting forcibly stops).

2.5 WAITING CONTROL FOR COMPRESSOR RE-STARTING
To re-start the compressor smoothly after compressor stops and after defrosting, it does not actuate the compressor for certain period.
Waiting time for compressor starting
10 minutes After compressor stops
3 minutes After defrosting
Caution
At once unplug, wait for 10 minutes, then plug in.
2.6 FAN MOTOR CONTROL FOR QUICK DEODORIZER
*When the green light is blinking after pressing the "QUICK DEODORIZER" button, the function of quick deodoring is
waiting .The situation of refrigerator is processing as below:
a.The refrigerator is defrosting .
b.The compressor is stopped,because temperature of the freezing compartment reachs setting of temperature.
c.The door of refrigerator compartment is opened.
When the above situation is solved , quick deodorization will be started automatically ,then the "QUICK
DEODORIZER"
light bright is on.
*Quick deodoring automatically ends ,then the green light is off. (Approx. 2~ 3 minutes)
2.7 FAN MOTOR CONTROL IN FREEZER COMPARTMENT
The fan motor (near FC evaporator )is controlled under below condition.
compartment is closed.Rotation speed changes on 4 degree according to atmosphere temperature and refrigerator compartment.
2.8 PROTECTION OF INVERTER CIRCUIT
When supply voltage drops, IPM protection operates, and compressor protection operates continuously, compressor stops at the moment and indicates code"H41".
