The manual baking cycle is started up and halted by the
key START/STOP. At the end of the cycle the signalling
flashing for 20 seconds (baking time or temperature of
the product probe) is accompanied by the sound of the
buzzer. Pressing the key MAN it is possible to manually
emit steam. Pressing the various keys under the displays
it is possible to modify the set point even of a cycle which
is already in operation.
REGULATION
Oven temperature control
• The cooking temperature is controlled according to the
programmed set-point and to the value read on the sensor
in the cooking chamber.
The temperature control is off if the value read on the
sensor is higher than the corresponding set-point (value
set-point cooking); lights up when the temperature goes
below the value (set-point - hysteresis). The hysteresis
has the value of the parameter "ISt ErE".
Fan control
• The fan runs in continuous mode with gear inversion every
3 minutes, with 15 seconds stop to allow the fans to stop.
Automatic steam control (SET POINT switched on)
• Steam can be activated only after at least 3 minutes'
functioning time have elapsed or if the temperature in the
cooking chamber is higher than the active set value minus
30 °C.
Manual steam control
• Steam can be activated only after at least 3 minutes'
functioning time or if the temperature in the cell is higher
than the active set value minus 30 °C. If the steam exit is
already automatically active, the button MAN can be
pressed but with no result. During the key pressure, the
steam emission and the visualization of steam time
elapsed will be shown (1,2,3,...9) on the display of the
steam percentage; on the key release or when 9 seconds
of manual steam have elapsed, the stop of steam emission
will come about and once again on the display the value
of the set up percentage of the steam for the working phase
will be visualized. When water is being sprayed, also the
point of the steam display is on.
ALARMS
The alarms' conditions are shown by means of blinking
messages on the display and by means of a buzzer (except
for the open door alarm). As soon as the alarm cause is
removed, the alarm is automatically cancelled and the oven
starts to work normally again. During the cooking time,
the oven overtemperature and chamber sensor failure
alarms cause the stop of the cooking cycle.
GB
Open door alarm
• When the door is opened the fans stop, the resistors and
the steam electro valve are disabled. The display shows
the following message:
not blinking and without buzzer.
The opening of the door micro-switch turns off the fans,
the oven resistances and the steam electrovalves. After 2
minutes from the opening of the door the light is turned off
automatically.
Chamber sensor failure alarm
• The display shows the following message:
blinking and the buzzer is enabled, the oven resistors are
disabled.
Core sensor failure alarm
• The display shows the following message:
blinking and the buzzer is ringing, the oven resistors are
disabled. By pressing the button START/STOP the alarm
stops and the oven starts to function normally again.
Oven overtemperature alarm
• This alarm is activated when the core sensor temperature
in the cooking cell goes over 310 °C (50 °C over the
maximum set value that can be selected).
The message teM is displayed alternatively with the tem-
perature / Err blinking with buzzer; the oven resistances
are deactivated.
Voltage drop alarm
• In case of drop of voltage, once the control has been fed
again functioning goes on in the same mode as before
the failure and the alarm is not signalled. With the baking
cycle started up, the alarm of the voltage drop will be
signalled, with the visualization of the message:
with flashing buzzer for 20".
Then the cycle starts again normally, with the count of the
remaining time.
