MICOM FEATURE CONTROLS
9) BUZZER CONTROL
(1) When effective key is pressed, the back light will be light, and the buzzer will ring once
(the voice will last for 0.2s, f=4.0kHz).
(2) If invalid key is pressed, there will be no buzzer ringing.
10) LIGHT CONTROL
(1) The refrigerator light will be on when the door of the refrigerating chamber opens. The
light will be forcefully closed if the door does not close within 10min. The light will be closed
when the door of the refrigerating chamber closes.
(2) The freezer light will be on when the door of the freezing chamber opens. The light will
be forcefully closed if the door does not close within 10min. The light will be closed when
the door of the freezing chamber closes.
(3) The photo-synthetic fresh keeping light will be on when the door of the refrigerating
chamber opens. The light will be closed when the door closes. The timing will be reset to
count from start.
11) DOOR OPENING ALARM
(1) According to the switching signals from door of refrigerating/freezing chamber, if the
door is open for over 1 min, the buzzer will ring to remind users to close the door. For every
15s, the buzzer gives three alarm sounds with the time interval of ringing for 0.5s and
suspending for 0.5s.
(2) The lamp of the refrigerating chamber will be automatically closed when the door of the
refrigerating chamber is open for over 10min. The lamp of the freezing chamber will be
automatically closed when the door of the freezing chamber is open for over 10min. The
compressor stops running. The buzzer rings continuously until door closing signal is
detected.
12) HARDWARE SELF-CHECK
(1) The buzzer rings twice, and all the lights of the LED panel are opened;
(2) All the lights of LED panel are closed after 2S.
(3) The circulating fan works for 5s after being opened every time.

(8) The evaporator heater strip opens (230V) and lasts for 5S.
(9) The compressor (230V) works for 5S.
(10) Test the communication interface. The refrigerating temperature is “P0” in normal
condition, and the refrigerating temperature is “P9” when there is fault.
(11) Test the sensor interface of the refrigerating chamber. The refrigerating temperature is
“P0” in normal condition, and the refrigerating temperature is “E1” when there is fault. No
words will be displayed.
(12) Test the sensor interface of the freezing chamber. The refrigerating temperature is
“P0” in normal condition, and the refrigerating temperature is “E2” when there is fault.
(13) Test the interface of defrosting sensor. The refrigerating temperature is “P0” in normal
condition, and the refrigerating temperature is “E3” when there is fault.
(14) “P0” will be showed in “Time-minute” when the door of the refrigerating chamber
closes, and “P1” when it opens. No alarm will be given when the door opens at this
moment.
(15) “P0” will be showed in “Time-minute” when the door of the freezing chamber closes,
and “P1” when it opens. No alarm will be given when the door opens at this moment.
(16) Press “MODE” key, the freezing temperature is “11” and the buzzer will ring in normal
