1) If Freezer Key + Fridge Key are pressed simultaneously for 6 seconds during normal operation, the
temperature setting display of fresh food and freezer compartments will blink ALL ON/OFF with 0.5 for
4 seconds.
2) At this moment, If Alarm Key after Freezer Key + Fridge Key is pressed, load condition display mode
will be returned with alarm. At LED all on state, only load condition display will blink ON/OFF with 0.5
seconds interval.
3) Load condition display mode shows the load that micom signal is outputting.
However, It means that micom signal is outputting, it does not mean whether load is operating or not.
That is to say that though load operation is displayed, load could not be operated by actual load error
or PCB relay error etc. (This function would be applied at A/S.)
4) Load condition display function will maintain for 30 seconds and then normal condition will be returned
automatically.
5) Load condition display is as below. Only the load control LED will blink with 0.5interval in "Display LED"
