5-1-5. Temperature control method
1. The compressor runs or stops and the 3-way valve opens or closes depending on the temperature sensed in the left and
right compartment.
2. If the temperature in either compartment is unsatisfactory, the compressor is turned on and the 3-way value is opened to
the affected compartment.
3. If the temperature in both compartments is unsatisfactory, the compressor is turned on and runs until both compartments
become satisfactory. The 3-way valve is opened and closed to each compartment alternatively until the temperature is
satisfactory.
4. During the seasoning cycle, if the temperature is low, the heater is turned on and if the temperature is high, the
compressor is turned on and the 3-way value is opened.
Note1) When the temperature is satisfactory in both compartments, the 3-way valve is open to whichever compartment that
has had a satisfactory temperature most recently.

5-1-6. Buzzer sound
When you press a button on the front display, you will hear a varying buzzer sound depending on the type and function.
(Refer to Buzzer operating circuit in p21).
5-1-7 Power failure compensation function
1. When the power is restored after an outage, the refrigerator performs the setting originally programmed except for Error
status and Test mode.
2. If the power fails during the seasoning process, there is not power outage compensation function and the storage defaults
to previously set Kimchi type and temperature of "Mid". (to protect excessive seasoning)
