OPERATING INSTRUCTIONS & INSTALLATION

3-16) Load Condition Display Function

1)If the freezing setting + the refrigeration setting keys are pressed simultaneously for about 6 seconds under normal operation condition, the freezer compartment and the refrigerator compartment temperature setting displays go on ALL ON/OFF for about 2 seconds with a 0.5 second interval.

2)I the freezing setting + the refrigeration setting keys are pressed simulyaneously then released, and the Fresh Zone setting key is pressed (to generate a ding-dong sound), the load status display mode is introduced.

3)Load status display mode tells what kind of load is output by the current MICOM signal. I tells only that a MICOM signal has been output but it does not confirm whether or not the load actually operates. So even if the display output shows that the load is operating , in reality the load might not operate due to load abnormality, bad relay on PCB etc. while as such this function may be used in A/S by application.

4)Load status display function is maintained for only 30 seconds after which it automatically returns to normal condition.

5)Relevant displays about load status is as follows.
