4.2. Control panel - version VII
MAIN SWITCH (Fig.2 No.1)
The main switch is situated on the upper part of the control
panel and is used to switch the appliance on or off. When
the marking of the knob points to “0” the appliance is
switched off. When selecting the cooking programmes
mentioned below the appliance is switched on automatically.
The indicator light above the knob lights up. To switch off
the appliance simply turn the main switch back to position
”0”. The indicator light goes out.
The five cooking programmes are activated by means of a
programme selection switch.
HOT AIR (Fig.2 No.11)
In this position only the heating of the cooking chamber is
activated, which means just hot air-operation.
STEAM (Fig.2 No.12)
In this position only the steam generator heating elements
are activated, which means just steam operation (100 °C).
STEAM 1 (Fig.2 No.13)
In this position the heating of the cooking chamber is
activated as well as the steam generator heating elements
in the proportion 75% hot air and 25% steam.
STEAM 2 - REGENERATION (Fig.2 No.14)
In this position the heating of the cooking chamber is
activated as well as the steam generator heating elements
in the proportion 50% hot air and 50% steam.
Low temperature steam, vacuum-cooking
(Fig.2 No.31)
In this position only the steam generator heating elements
are activated, which means just steam operation
(temperature range adjustable between 30°C and 99 °C).
COOKING CHAMBER TEMPERATURE
(Fig.2 No.17)
Setting of the required temperature inside the cooking
chamber. The temperature may be set anywhere between
50° and 300° C. The markings on the knob allow the
approximate regulation of the temperature value, while the
luminous digital indication (display) above the knob allows
a precise regulation. During the process of programming
the temperature value is blinking. If no further change is
made, after 3 seconds the display will indicate the tempe-
rature value actually measured by the temperature sensor
inside the cooking chamber, thus enabling a constant
control of the actual temperature inside the cooking
chamber.
In the “HOT AIR” cooking mode, the programmable
maximum temperature is 300° C. In this case the
temperature range between 250° and 300°C is limited to
10 minutes. In the ”STEAM” cooking mode, the temperature
is automatically limited to 100 °C. In the ”STEAM 1" and
”STEAM 2” cooking modes, the programmable maximum
temperature is 250° C. In the ”LOW-TEMPERATURE
STEAM” cooking mode, the programmable temperature
goes from 30° to 99° C.
ACTUAL COOKING TIME (Fig.2 No.18)
Programming the desired cooking time. The time scale is
divided into three different graduations :
Range from 1 - 20 min.: This enlarged range in 1-minute
stages is provided for short term cooking.
Range from 20 - 120 min.: This range in 4-minute stages
is provided for long term cooking.
Range ¥: This sign of infinity indicates continuous
operation. In this position the appliance is preheated or is
working in the “stand-by” operation.
By turning the knob, the timer is activated and the cooking
process starts, if the desired cooking programme and tem-
perature has been preset. During the course of cooking
process the green indicator light above the knob lights up.
As soon as the cooking time is over, the indicator light
goes out and an audible signal is activated.
If the cooking process is carried out by using the core
temperature sensor, the timer must be in the “0” position.
CORE TEMPERATURE (Fig.2 No. 19)
In this cooking process the cooking time is determined by
the set core temperature. For this operation it is necessary
to set the timer to the “0” position.
By turning the knob to the right the required core tempera-
ture can be increased up to 99°C maximum.
By turning the knob to the left, the temperature is lowered,
with a programmable temperature value of 0°C minimum.
During the programming stage the set temperature value
is blinking on the display above the knob. If no further
change is made, after 3 seconds the display will indicate
the temperature value actually measured by the core tem-
perature sensor, thus enabling a constant control of the
roast during the entire cooking process.
REDUCED FAN SPEED (Fig.2 No. 32)
When pressing this button the indicator light above the
symbol lights up. If the appliance has not yet been started
and therefore the fan is not yet in operation, the fan motor
will automatically operate at reduced speed after starting
the cooking process. If on the contrary the fan motor has
been started at high speed, it will be interrupted shortly
(approximately 15 seconds), after which the motor
automatically starts at reduced speed.
To operate the appliance with normal fan speed, just press
this button again. The indicator light goes out and the motor
automatically changes to normal speed.
Note: when the fan reduced speed is enabled, the hot air power
gets automatically reduced to 50% :
EMPTYING THE STEAM GENERATOR
(Fig.2 No.23)
The appliance is fitted with a motor-operated discharge valve.
Under normal conditions it is closed and this is shown by
