Control and Information System
The control and information system consist of the temperature display,
an optical warning display and an acoustic warning.
The system warns if:
– the temperature in the freezer compartment is too warm;
– there are 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.
3
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.
