Control and Information Systems
The control and information systems consist of a temperature display,
an optical warning display and an acoustic warning device.
The system warns of:
– open appliance door (not included with all models);
– power interruption (not included with all models);
– excessive temperature in the freezer compartment;
– possible partial or complete thawing of frozen goods;
– functional disturbances at the appliance.
"Open Door"-Warning (not included with all models!)
When the door is open the red warning display blinks. If the door
remains open for more than 80 seconds, an audible warning also
sounds. If you need more time for loading or rearranging frozen goods,
you can switch off the audible warning by pressing the WARNING OFF
button.
Power Interruption (not included with all models!)
If the power supply is interrupted, an audible warning sounds at
20 second intervals. In addition, the current actual temperature in the
freezer compartment is indicated in blinking fashion by the tempera-
ture display (2 seconds on, 2 seconds off). After one hour the audible
warning only sounds at 40 second intervals.
The audible warning can be switched off for about 2 hours with the
WARNING OFF button.
In the event of a power interruption, the control and information
systems can maintain operation of the temperature display and
warning signal for up to 12 hours.
Temperature Warning
The red warning display blinks and an audible warning sounds, as soon
as the temperature in the freezer compartment climbs to more than
5°C above the selected SET temperature. A rise in temperature of more
than 5°C may be caused by:
– frequent door opening for long periods of time;
– loading with large quantities of warm foods;
– an error at the appliance.
