Control and Information Systems
The control and information systems consist of temperature displays,
an optical warning display and an acoustic warning.
The system warns if:
– when the appliance door is open
– the temperature in the freezer compartment is too high;
– functional faults with the appliance.

"Open Door"-Warning

If the fridge or freezer door is left open the red warning display will
flash and an acoustic warning tone will sound
– after approx. 80 seconds if the freezer door is left open
– after approx. 5 minutes if the fridge door is left open
If you need more time to load or rearrange refrigerated or frozen foods,
you can switch off the warning tone by pressing the WARNING OFF
button.
If the doors are still left open the warning tone will sound again at the
end of the appropriate period of time.
If the doors remain open for longer than 80 minutes the warning tone
will switch itself off automatically.
The red warning display will go off when the doors are closed.

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 of 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 lower than -11°C.
3 The warning tone switches off automatically after one hour, even if the
ACTUAL temperature is still different to the DESIRED temperature. The
red warning light continues to flash.
