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 of food with wet fillings or
toppings, e.g. pizza and flan.
– 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.
18
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,
e.g.

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.

19
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.

20
Special functions ( The special functions include:

Steam cooking For system steam cooker (option available from

– main oven specialist dealers)

Dough proving The dough proving function provides ideal conditions

– main oven inside the oven for getting yeast dough to rise.
Temperature: 35 – 38° C
Humidity: 75 – 100%
Advantages:
– rapid and uniform increase in volume of dough
– dough does not dry out
– dough does not form a skin which means that it
very easy to process and work into the required
shape
– exclusion of unfavourable external influences
(e.g. draughts).
– yoghurt can be made.

Oven Cleaning Oven cleaning is a regeneration programme.

If the self-cleaning panels in the oven are no longer
adequately cleaned during normal day-to-day
operation, they will be regenerated with this function.
They will then be fully functional again.

Light The oven light is switched on.

After 30 minutes the light automatically switches off
again. The oven does not heat up.

Baking
Using baking tins Always place baking tins in the centre of the
baking wire shelf.
We recommend dark metallic baking tins.

Notes Light coloured baking tins made from thin-wall

materials lead to longer baking times and uneven
browning of the cake.
You can influence the degree of browning by
changing the temperature setting.
If a cake collapses after removing it from the oven,
consider using a longer baking time, or use a slightly
lower temperature setting.

Using tinplate baking tins * Circotherm Shelf position 1

/ Top/bottom heat Shelf position 1

If the cake bottom gets too dark:

Check the shelf position. Shorten the baking time,
and possibly use a lower baking temperature.
If the cake bottom stays too light:
Check the shelf position. Increase the baking time,
select a lower temperature, or use a dark metal
baking tin.
Do not place baking forms or high cakes too close
to the rear oven wall.

To save energy Preheat only if expressly required by the recipe.

Dark baking tins have a higher degree of heat
absorption.
Residual heat: In the case of longer baking times,
you can switch off the oven 5-10 minutes before the
full baking time has elapsed.

28
Roasting Place the wire shelf in the universal pan and slide
both into the oven at the same shelf position.
Meat can be roasted in the oven in a particularly
economical fashion if the weight of the cut exceeds
750 grams.

Roasting in an uncovered Rinse the universal pan and/or the roaster with
pot water, and place the meat into it.
With fat meat and poultry, pour 125 to 250 ml of
water (to suit the size and kind of roast) into the
universal pan. At your discretion, baste lean meat
with fat, or cover it with bacon strips.
The roast drippings collecting in the universal pan
make a tasty gravy. Dissolve the drippings with hot
water, bring to a boil, thicken with corn starch,
season to taste and, if required, pass it through a
strainer.
No preheating is required. Save energy by putting
the roast into the oven while it is still cold.
Roasting in a covered pot Place the meat into the roasting pot (or Dutch oven),
cover it with a matching lid, and place it on the wire
shelf in the oven. We recommend that beef roast be
prepared in a covered roasting pot.

For roasting, use only cookware with oven-proof
handles.
Prepare large roast directly in the universal pan,
without using the wire shelf.
Smaller cuts of meat can be roasted on aluminium
foil. To do so, bend the edges of the foil upward, as
if to form a dish, and place it on the wire shelf.
After the end of the selected roasting time and with
the oven switched OFF, leave the roast in the closed
oven for approx. 10 minutes.

Grilling
Exercise CAUTION when grilling.
Always keep children at a safe distance.
Notes on grilling Always close the oven door when grilling.
The grilling temperatures are variable.
Always use the wire shelf and the universal pan.
Always place food to be grilled in the centre of the
wire shelf.
If the grill element (heating element) switches OFF
automatically, the overheating protection was
activated.
The radiator will be reactivated after a short period
of time.
Place the wire shelf into the universal pan and
slide them together into the same shelf position.

31
Circo-roasting Use this method for particularly crispy poultry or
roast (e.g., pork roast with crackling).
Use the wire shelf and universal pan together. Turn
large roasts after about half of the total grilling time
has elapsed.
To prevent breakage after removing them from the
oven, place glass utensils on a dry kitchen towel
instead of cold or wet surfaces.
Dependent on the type of food being prepared,
combination hot-air and surface grilling can cause an
increased degree of oven soiling. Therefore, to
prevent burning-in of the soil, thorough cleaning of
the oven is recommended after each use.
Whole poultry should be turned after approx.
two-thirds of the cooking time has elapsed.
With duck and goose, pierce the skin under the
wings to allow excess fat to drain off.
After the end of the selected roasting time and with
the oven switched OFF, leave the roast in the closed
oven for approx. 10 minutes.

Surface grilling Used for smaller dishes having little height/thickness.

Large area grill Always use the wire shelf and universal pan together.
Turn the food after approx. two-thirds of the grilling
time has elapsed.
At your discretion, lightly baste the wire shelf and the
food with oil.

Defrosting and cooking
Defrosting with
Circotherm

Important heating system For defrosting and cooking of frozen or deep-

information frozen foods, use only the circotherm heating
system.
With all deep-frozen foods, follow the food
processing company‘s instructions on the
package.
As a rule, defrosted frozen or deep-frozen foods
(especially meats) require less cooking time than
fresh products, since freezing has a pre-cooking
effect.
If frozen meat is placed in the oven, the defrosting
time must be added to the required cooking time.
Always defrost deep-frozen poultry before cooking
because the giblets must be removed.
For cooking deep-frozen fish, use the same
temperatures as for fresh fish.
Deep-frozen ready-to-eat meals in aluminium
dishes may be placed into the oven several at a
time.
Shelf position With 1 baking sheet: Shelf position 1
With 2 baking sheets: Shelf position 1 + 3
for the main oven.
All stated times are approximate guidelines that
vary with the shape and volume of deep-frozen
products.

33
Defrosting and cooking Raw deep-frozen products or foods from a
freezer always defrost at 50° C.
Higher defrosting temperatures may cause the food
to dry out.
Defrost deep-frozen meals packed in aluminium
foil or closed aluminium containers at a setting of
130 – 140° C.
Defrost and warm up deep-frozen baked goods at
100 – 140° C. Brush bread, rolls or yeast pastry
lightly with water to make the crust more appealing.
Defrost dry deep-frozen yeast cakes at
160 – 170° C for 20 – 30 minutes.
Defrost moist deep-frozen yeast cakes (with fruit
topping) at 160 – 170° C for 30 – 50 minutes after
wrapping in aluminium foil to prevent cake from
drying out.
Defrost and toast deep-frozen toast (with topping)
at 160 – 170° C for about 20 minutes.
Frozen pizza:
Please follow the manufacturers’ instructions.

Cleaning and Care
Important cleaning For cleaning, do not use abrasives, no corrosive
basics cleaners, and no sharp objects.
Do not scratch off burnt-in food residues, but soak
them off with a moist cloth and dishwashing
detergent.
Cleaning products we particularly recommend can
be purchased from our customer service.

Appliance exterior
Stainless steel/ Use commercially available detergents applied to a
aluminium front soft, moistened cloth or a chamois.
Do not use aggressive cleaning agents, abrasive
sponges, or coarse cleaning cloths.
On heavy soiling use commercial cleaning agents on
matted stainless steel/aluminium surfaces.
Please observe the manufacturer’s instructions.
Enamel and glass Use commercially available detergents applied to a
soft, moistened cloth or a chamois.
Oven door pane The temperature of the pane inside the oven door is
reduced by a heat-reflecting coating.
The reduced temperature ensures that visibility
through the oven door window is not impaired.
When the oven door is open, this coating may have
a bright appearance. This is quite normal and does
not indicate a quality defect.

Oven interior Clean the oven after each use, especially after
roasting or grilling.
Food remnants burn in when the oven is reheated.
The baked in remnants are very difficult to remove
once burnt in.

39
 Note:
To prevent soiling use:
• CircoTherm hot air. The CircoTherm hot air
mode causes less soiling than the others.
• the universal pan to bake very moist cakes.
• suitable utensils (frying pan) for frying.
For easier cleaning
you can switch on the oven lamp and take off the
oven door.
For cleaning the mating surface of the oven door at
the front of the oven, the door should be removed.
Enamel areas in the oven Use hot soapy water or a vinegar solution.
It is best to use oven cleaner if the oven is very dirty.
Only use oven cleaner in a cold oven.
We recommend cleaning gels because these can be
applied with greater precision.

Do not clean the warm oven with any of the
cleaning products specifically designed for this
purpose.
Leave the oven open so that it can dry after
cleaning.
Note:
Enamel is baked on at very high temperatures.
This can cause some slight colour variation. This is
normal and does not affect the function. Do not use
coarse scouring pads or strong cleaning agents to
remove such discolorations.
The edges of thin trays cannot be completely
enamelled. As a result, these edges can be rough.
Anti-corrosion protection is guaranteed.

40
Catalytic oven
surfaces
Cleaning the catalytic The rear wall, the oven ceiling and the side walls of
surfaces of the oven the oven are coated with self-cleaning enamel. The
surface cleans itself while the oven is in operation.
Large splashes sometimes only disappear after the
oven has been used several times.
Never use oven cleaner on catalytic surfaces of the
oven.
Should the enamel become slightly stained, this will
not affect its self-cleaning properties.

41
Oven Cleaning
Automatic oven cleaning Oven cleaning is a regeneration programme.
If the self-cleaning panels in the oven are no longer
adequately cleaned during normal day-to-day
operation, they will be regenerated with this function.
They will then be fully functional again.
Take the accessories and utensils out of the
oven.
Before switching on automatic oven cleaning,
thoroughly clean the areas of the oven that do not
have self cleaning panels, e.g. enamelled areas such
as the oven floor, inner door. This will prevent residue
from burning in.
You can select the duration of automatic oven
cleaning via the electronic clock.

The oven becomes very hot during automatic
oven cleaning – always keep children away.
