STEAM INJECTION
7.1
Preliminary considerations
The steam injection functioning mode depends on parameter t0.
If the parameter t0 is set at 0, pressing the
key will cause the injec-
tion of the steam for the time established with parameter t2 or for the
entire duration that the key is pressed; the parameter t1 establishes the
minimum time that will pass between the two successive injections.
If the parameter t0 is set at 1, pressing the
key will enable the
automatic injection of the steam (in cyclical mode: the parameter t2
establishes the duration of injector switch-on and the parameter t1
establishes the duration of switch-off).
7.2
Quick setting of parameter t2
• make sure that the instrument is in the on state and no procedure is
in progress
• press
and
: the central display will show “t2”, the lowest
one the corresponding value and the LED
will flash.
• press
or
within 15s.
The parameter t2 can be set between 1 and 250 ds.
• press
: the LED will switch-off, after which the instrument will
exit the procedure.
To exit the procedure in advance:
• do not operate for 15s (any modifications will be saved).
7.3
Activation of the injector in manual mode (only if
the parameter t0 is set at 0)
• make sure that the instrument is in the on state and no procedure is
in progress
• press
: the LED switches on and the injector will be activated,
both for the time established with parameter t2 or for the
entire duration that the key is pressed.
The injector cannot be deactivated in manual mode.
7.4
Enabling of the automatic injection of the steam
(only if the parameter t0 is set at 1)
• make sure that the instrument is in the on state and no procedure is
in progress
• press
: the LED will switch-on and the injector will be acti-
vated in cyclical mode according to that established with
the parameters t1 and t2 (until the key is pressed again).

AIRHOLE
8.1
Preliminary considerations
The airhole is activated in the following conditions:
• before the conclusion of the cooking timer count (the time estab-
lished with parameter c5), for the time established with parameter c6
• in manual mode, by pressing the
key for the time established
with the parameter c7.
8.2
Quick setting of parameter c7
• make sure that the instrument is in the on state and no procedure is
in progress
• press
and
: the central display will show “c7” and the low-
est one the corresponding value; the left part
and the LED will flash.
The parameter c7 is displayed in the minutes:seconds format.
To modify the minutes:
• press
or
within 15s
• press
: the right part will flash.
To modify the seconds:
• press
or
within 15s.
• press
: the LED will switch-off, after which the instrument will
exit the procedure.
The parameter c7 can be set between 00:00 and 60:00 min:s.
To go back to previous levels:
• press
several times during the procedure.
To exit the procedure in advance:
• do not operate for 15s (any modifications will be saved).
8.3
Activation of the vent in manual mode
• make sure that the instrument is in the on state and no procedure is
in progress
• press
: the LED will switch-on and the vent has been acti-
vated, both for the time established with parameter c7.
To deactivate the airhole in manual mode.
8.4
Deactivation of the airhole in manual mode
• make sure that no procedure is in progress
• press
: the LED will switch-off.

enabled
if flashing:
• the quick setting of the parameter t2 will be in progress
(see paragraph 7.2)
airhole LED
if it is on, the vent will be activated in manual mode
if flashing:

clusion of the cooking timer count (parameter c6)
• the quick setting of the parameter t2 will be in progress
(see paragraph 8.2)
chamber light LED
if it is on, the chamber light will be on
°
C
degree Celsius LED
if it is on, the unit of measurement of the temperatures will
be the degree Celsius (parameter P2)
°
F
degree Fahrenheit LED
if it is on, the unit of measurement of the temperatures will
be the degree Fahrenheit (parameter P2)
on/stand-by LED
if it is on, the instrument will be in the programmed switch-
on state or in the stand-by state
if it flashes, the cooking timer count will be in progress and
the instrument will switch-off when the count ends

if it is on, the quantity shown on the lowest display will be
the value of the cooking timer or its count if the timer is
active
if flashing:
• cooking timer setting will be in progress
• the cooking timer count will be in progress but the low-
est display will be showing another quantity

on state
if it flashes, setting of the day and time of programmed
switch-on will be in progress

ALARMS
11.1 Alarms
CODE MEANING
AL1
top temperature alarm
Remedies:
• check the top temperature
• see parameters A1 and A3
Consequences:
• the instrument continues to function regularly
AL2
floor temperature alarm
Remedies:
• check the temperature of the floor
• see parameters A5 and A7
Consequences:
• the instrument continues to function regularly
PF1
power supply cut-off alarm during cooking timer count
with duration shorter than the time established with pa-
rameter r13
Remedies:
• press a key to restore normal display
• check the causes of the power cut
Main consequences:
• the count will continue even when the instrument is not
powered
• the instrument continues to function regularly
PF2
power supply cut-off alarm during cooking timer count
with duration longer than the time established with pa-
rameter r13
Remedies:
• press a key to restore normal display
• check the causes of the power cut
Main consequences:
• the count will be interrupted
When the cause of the alarm has disappeared, the instrument restores
normal functioning, except for power cut alarms during the cooking
timer count (codes “PF1” and “PF2”) which require pressing the button.

INTERNAL DIAGNOSTICS
12.1 Internal diagnostics
CODE MEANING
Pr1
top probe error
Remedies:
• see parameter P0
• check the integrity of the probe
• check the instrument-probe connection
• check the chamber temperature
Main consequences:
• the top output will be deactivated
Pr2
floor probe error
Remedies:
• the same as the previous case but relative to the floor
probe
Main consequences:
• the floor output will be deactivated
rtc
clock error
Remedies:
• set the day and real time again
Main consequences:
• programmed switch-on will not be available
When the cause of the alarm disappears, the instrument restores nor-
mal functioning, except for the clock error (“rtc” code) that requires
setting of the day and real time.
