Control and Information Systems
The control and information systems consist of the temperature display,
an optical warning display and an acoustic warning.
The system warns if:
– if the temperature in the freezer compartment is too warm;
– functional disturbances at the appliance.
Temperature Warning
The red warning display flashes and an audible warning sounds, as soon
as the temperature in the freezer compartment is warmer than -12 °C.
A rise in temperature may be caused by:
– frequent door opening for long periods of time;
– loading with large quantities of warm foods;
– high ambient temperature;
– an error with the appliance.
The audible warning can be switched off with the WARNING OFF but-
ton. Both warning display and audible warning are automatically
switched off, when the ACTUAL temperature in the freezer compart-
ment falls to the range of the display.

The warning tone switches off automatically after one hour, even if the
ACTUAL temperature is still at a variance with the DESIRED tempera-
ture. The red warning light continues to flash.
Function Errors
If the electronics in the appliance have detected a fault that prevents
the ACTUAL temperature being measured, all the lights in the tempera-
ture display will flash. The appliance will continue to function using a
backup programme until a Service Force engineer has repaired the
appliance.
