The rotary selector is used to adjust values. The display shows a status bar, settings areas, and a rotation direction indicator.
Heating and Temperature: The oven features a temperature indicator with bars showing heating phases and residual heat. It indicates when the optimum temperature for placing a dish has been reached. The cooling fan operates as needed to prevent overheating and continues after operation to cool the compartment.
Automatic Programmes: The oven offers automatic programs for various dishes, including poultry, meat (beef, veal, pork, lamb, mutton, game), fish, meat loaf, and stew. These programs simplify cooking by automatically adjusting settings based on the weight and type of food. Users can also adapt program results to individual requirements.
