Operation Modes
12
Convection
The back heater and the fan operate simultaneously in
order for the hot air to circulate constantly. This mode is
appropriate for roasting meat and baking on several shelves
simultaneously. Cooking temperature should be set lower
than conventional operation.
Convection and lower heater
The back heater, the fan and the lower heater operate
simultaneously. This is suitable for making pizza, pastries,
fruit cakes or baked cheesecakes.
Defrosting
The air is circulated without any heater being turned on. Only
the fan is in operation. This is used for defrosting frozen food.
Lower heater and fan
The lower heater and the fan operate simultaneously. Used
for baking sweet bread dough and preserving fruit and
vegetables. Use the first shelf position from the bottom and
shallow rather than deep baking trays.
Lower heater/ Steam clean
The bottom heater is activated. Select this mode when you
wish to cook the bottom side of the dish more thoroughly
(e.g. for deep pastry with fruit filling). Set the temperature with
the temperature selection dial. The lower heater can also be
used for cleaning the oven, for instructions please see the
"Maintenance and cleaning" section on page 29.
