MICOM Function and Description of Circuit
7) Operation in Response to Ambient Temperature
The storage senses the ambient temperature and adjusts the temperature in the compartments
accordingly. This keeps the storage from being too cold or too warm because of seasonal variations
and maintains exact temperatures in the compartments.
8) Sequential Operation of Components
Components (Compressor, 3-way Valve, Left/ Right Ripening Heater and Condensation Heater) are
operated in a specific order to prevent damage, noise, and electrical overload caused by
simultaneous operation of all parts when the unit is started and after completing the self-test routine.
❇
Operation order may slightly vary depending on temperature setting.

Temperature of Left or
Right sensor is >10°C

moving or after a long
period of no use.)
Condensation
heater is set for
always ON,
but if the left and
right compartment
are simultaneously
turned off,
condensation
heater is turned
off, too.
The 3-way valve is
opened to both
compartments for 3
minutes; then it is
opened to either
the left or the right
compartment,
depending on the
temperature in the
compartments.
