indicated in paragraph 4.5)

of the steam cooking phase (parameter c6)

• parameter c7 is being modified (with the procedure

indicated in paragraph 4.5)

be the degree Celsius (parameter P2)

Degrees Fahrenheit LED

if it is on, the instrument will be in the programmed switch-
on status or in the stand-by status

delay programmed switch-on LED

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

timer cooking phase duration LED

will be the duration of the cooking phase
if flashing:
• modification of the cooking phase duration is being

modified (with the procedures indicated in paragraphs
4.3, 4.5 and 4.7)

• the count of the duration of the cooking phase will be in

progress but the lower part of the display will be showing
another quantity

display will be the real time
if it flashes, setting of the day and real time will be in progress

set

set-point LED
if on, the quantity displayed by the lower part of the display
will be the value of the work set-point of the phase in
progress or the core set-point.

• the quantity displayed by the lower part of the display

ALARMS

Alarms

CODE MEANING

chamber temperature alarm
Solutions:
• verify the chamber temperature
• see parameters A1 and A3
Consequences:
• the alarm output will be switched-on
• the acoustics output and the buzzer output will be

switched-on

Multifunction input alarm (only if parameter i5 is set at 4)
Solutions:
• check the causes that caused activation of the input
• see parameters i5 and i6
Main consequences:
• the temperature regulation output will be switched-off
• the grill will be off
• the airhole will be off
• the steam injector will be off
• the fan will be off
• the count of the duration of the cooking phase will be

suspended

PF1

power cut alarm during the cooking phase with interruption
of duration shorter than the time established with parameter
r13
Solutions:
• press a key to restore the normal display
• check the causes of the power cut
Main consequences:
• the count will continue even when the instrument is not

powered

• when the power supply is restored, the acoustic output

and the buzzer output will be switched-on

PF2

power cut alarm during the cooking phase with interruption
of duration longer than the time established with parameter
r13
Solutions:
• press a key to restore the normal display
• check the causes of the power cut
Main consequences:
• the cooking phase will be interrupted
• when the power supply is restored, the acoustic output

and the buzzer output will be switched-on

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

16.1

Internal diagnostics

CODE MEANING

Pr1

chamber probe error
Solutions:
• see parameter P0
• check the integrity of the probe
• check the instrument-probe connection
• verify the chamber temperature
Main consequences:
• the temperature regulation output will be switched-off
• the acoustics output and the buzzer output will be

switched-on

• no phase can be started-up
• if a phase is in progress, this will be interrupted

Pr2

core probe error
Solutions:
• the same as the previous case but relative to the core

probe

Main consequences:
• the acoustics output and the buzzer output will be

switched-on

• the core cooking phase cannot be selected
• if a core cooking phase is in progress, this will last for the

time established with parameter d3

rtc

clock error
Solutions:
• set the day and real time again
Main consequences:
• programmed switch-on will not be available
• the acoustics output and the buzzer output will be

switched-on

When the cause of the alarm disappears, the instrument restores normal
functioning, except for the clock error (“rtc” code) that requires setting
of the day and real time.
