5.4 Automatic altitude adjustment
Altitude adjustment is carried out automatically for the steaming, regenerating, baking like professionals
and hot air with steam vapour modes. Automatic altitude adjustment enables the hot air temperature to
be regulated with some difference in temperature below the maximum possible steaming temperature.
This ensures that the air in the oven is always sufficiently moist and that there are no drying effects on
the food.
This maximum possible steam temperature is contingent on the ambient pressure of the appliance. The
ambient pressure is primarily affected by the altitude above sea level and by atmospheric pressure and
therefore by the weather.
Altitude adjustment is carried out in the following steps:
• The water in the evaporator is heated up with the evaporator heater operating at full power.
• If, during a certain period of time and for the purpose of measuring the temperature in the steam
generator, the temperature sensor does not register any change in temperature, this temperature
will be taken as the maximum possible water temperature and therefore also as the maximum
possible steam temperature.
• Should, during the process of altitude adjustment and within a certain period of time, the water
temperature not rise above a certain level, the clear text display will indicate “F7: call service“
(evaporator heater defect).
