MICOM Function and Description of Circuit
2. If the temperature in
3-way valve 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 ripening cycle, if the temperature is LOW, the heater is turned ON; if the temperature is
HIGH, the compressor is turned on and the 3-way valve is opened.

4) Condensation Heater Control
1. At the top of the storage around the gasket, the condensation heater is always ON.
2. If you turn both compartments OFF, the condensation heater is also turned OFF; if you turn either
compartment on, the condensation heater is turned on.
5) Buzzer Sound
1. If you press a button on the control panel, the buzzer sounds Ding-Dong. (See Buzzer Operation
circuit, page 23, section 2.)
2. If you begin entering a program by pressing buttons but don't complete the program, the buzzer
sounds Ding.
6) Power Failure Compensation Function
1. When the power is restored after an outage, the storage performs the setting originally
programmed except for Failure Status and Test Mode.
2. If the power fails during the ripening process, there is no power outage compensation function and
the storage defaults to Kimchi/Mid status to protect against excessive ripening.
