Oven operating modes
Here you will receive an overview of the four oven
functions: hot air functions, conventional functions,
grill functions and special functions. The oven
functions are divided into the following operating
modes.
Hot air functions *The hot air functions include:
Circotherm A fan system located in the rear oven wall circulates
the circotherm in the oven, achieving an especially
effective heat transfer to the food being baked or
roasted.
Advantages:
–Simultaneous baking and roasting is possible in
the main oven on up to 3 shelf positions
–Baking and roasting is possible in the mini oven
on one shelf position only
–low soiling of oven interior
–shorter preheating times
–low oven temperatures
–gentle defrosting, see the Defrosting and cooking
section for adjusting the defrost setting.
Circotherm intensive The Circotherm intensive adds the bottom heat to
the circotherm.
Advantages:
–Fresh preparation with a high ”moisture content”,
e.g. pizza and juicy cakes with crisp base.
–Especially suited for frozen products, e.g. pizzas,
chips etc.
Bread baking Bread baking with hot air function.
Adjustable 180 – 220° C.
Note Rapid heat up
Can be selected for Circotherm or bread baking
setting.

19
Conventional
functions /The conventional functions include:
Top/bottom heat The food being baked or roasted is exposed to heat
(Conventional heating system) radiation from heating elements located at the top
and bottom of the oven cavity.
Baking and roasting is possible on one shelf position
only.
Advantages:
–Baking of cake with wet fillings, pizza, quiche.
Bottom heat With this setting, only the heating element at the
bottom of the oven cavity is activated.
Advantage:
–Particularly useful with dishes and baked goods
that require a distinctive bottom crust or
browning.
Use just before the end of the baking or roasting
time.

20
Grill functions )The grill functions include:
Large area grill The food being prepared is exposed to heat radiation
from the heating element at the top of the oven
cavity.
Advantages:
–Particularly effective with flat, small cuts of meat,
i.e., steaks, sausages, fish, vegetables and toast.
–the entire grilling surface heats up
–especially useful with large amounts of food.
Small area grill Advantages:
–only the centre area of the grilling surface heats
up
–especially useful with small amounts of food
–energy-saving operation.
Circo-roasting With circo-roasting, the air circulating fan and the
grilling elements are activated alternataly.
The heat generated by the grilling element is evenly
distributed in the oven cavity.
Advantage:
–Particularly effective with poultry.
