INTERMITTENT FAN OPERATION (Fig.4 No.8)
Intermittent fan operation is obtained in this position, i.e.
the fan starts and stops at programmed intervals.
This intermittent control is activated when the regulator
stops the heating of the cooking chamber; i.e. when the
set temperature is reached. This control does not depend
on the programmed fan speed.
During the preheating stage, it is not activated. When
inserting this variant, the indicator light above the button
comes on.
ECO-DELTA COOKING (Fig.4 No.9)
For this cooking process, a temperature value anywhere
between 0°C and 99°C may be selected by which the
cooking chamber temperature will be above the product
core temperature.
Upon activating this programme, the indicator light above
the button comes on.
PROGRAMMING COOKING START TIME
(Fig.4 No.10)
The appliance automatically comes on and starts the
cooking process once the time set by means of this button
has elapsed.
While this programme is in operation, the indicator light
above the button remains on.
After having programmed the cooking time, you have
to set the cooking proces you intend to use as in 2nd
Cook Step.
HOT AIR (Fig.4 No.11)
In this position only the heating of the cooking chamber
is activated, which means just hot-air operation.
STEAM (Fig.4 No.12)
In this position only the steam generator heating elements
are activated, which means steam operation between 30
- 100°C.
STEAM 1 (Fig.4 No.13)
In this position the heating of the cooking chamber is
activated as well as the steam generator heating elements
in the proportion of 75% hot air and 25% steam.
STEAM 2 - REGENERATION (Fig.4 No.14)
In this position the heating of the cooking chamber is
activated as well as the steam generator heating elements
in the proportion of 50% hot air and 50% steam.
SET POINT (Fig.4 No.15)
During a cooking process, the actual temperature and time
values, i.e. the measured values, are shown on the
respective displays.
If the user wishes to know which temperatures and cooking
times have been set, the SET POINT button must be
pressed. The displays will show the set values, i.e. the
values which should be reached. The indicator light of this
button comes on. The real value, i.e. the value read inside
the cooking chamber will be automatically displayed about
5 seconds after having released the button.
HUMIDITY REGULATION (Fig.4 No.16)
Humidity regulation operates in the following cooking
programme:
STEAM 2 - Regeneration
This regulation is used to change and consequently to
establish individually the degree of humidity of the cooking
mode within a certain range.
It is also possible to store the humidity level required in
the corresponding cooking programmes.
Pressing the increase and decrease buttons sets the
required humidity in the cooking chamber, which may be
regulated by levels.
COOKING CHAMBER TEMPERATURE
(Fig.4 No.17)
The temperature may be set anywhere between 30°C and
300°C with hot air, using the increase and decrease buttons.
The temperature range between 250°C and 300°C is limited
to a time of 10 minutes.
This wide temperature range ensures fast preheating of
the empty appliance or a high stand-by temperature ready
for loading the food. In the Steam 1 and Steam 2 cooking
modes, the programmable temperature goes from 30°C to
250°C. In the Steam cooking mode, the temperature is
automatically limited to 100°C.
ACTUAL COOKING TIME (Fig.4 No.18)
A cooking time of anywhere between 1 minute and 8 hours
as well as continuous operation may be set by means of
the increase and decrease buttons.
During the programming stage the set cooking time appears
on the display above the increase and decrease buttons.
Continuous operation is activated by setting a time which
exceeds 8 hours or by directly pressing the decrease button
in the neutral position. CONT appears on the display.
Note: selecting a cooking process which stops when the
set core temperature is reached, excludes the possibility
of programming a cooking time.
CORE TEMPERATURE (Fig.4 No.19)
The required temperature may be set anywhere between
0°C and 99°C by means of the increase and decrease
buttons. With this procedure the cooking time depends on
the set core temperature of the roast.
In fact, apart from the core temperature, the only parameter
to be set is the cooking chamber temperature. It is
impossible to set the time.
