they cannot be removed without the aid of a tool.
1.3 Electric connection
With reference to the wiring diagram, the serial port is the communi-
cation port with the supervising system (through a serial interface, via
TTL, with MODBUS communication protocol) or with the program-
ming key; the port must not be used for two purposes at the same time.
Recommendations for the electric connection:
• do not operate on the terminal boards using electric or pneumatic
screwdrivers
• if the instrument has been taken from a cold place to a hot place, the
humidity could condense inside; wait for about one hour before
applying power
• check that the power supply voltage, the frequency and the electric
operational power of the instrument correspond with those of the
local power supply
• disconnect the power supply before performing any type of mainte-
nance
• supply the probe with protection able to isolate it from any contact
with metal parts or use isolated probes
• do not use the instrument as a safety device
• for repairs and information regarding the instrument, contact the

2 PRELIMINARY CONSIDERATIONS
2.1 Preliminary considerations
It is possible to select the utilities managed by the digital outputs (i.e.
relays K1, K2 and K3) among a series of four combinations (instrument
codes 1, 2, 3 and 4); a fifth combination (instrument code 0) allows to
set the utility managed by each output independently.
INSTR. CODE
(default) regulation
To set the instrument code, see paragraph 4.1; to set the utility managed
by each output, see paragraph 4.2.
2.2 Management of the utilities
Temperature regulation.
The output activity mainly depends on the chamber temperature, the
work set-point and the parameter r0.
Airhole.
The output is activated in the following conditions:
• before the conclusion of the cooking timer count (of the time established
with the parameter c5), for the time established with parameter c6
• in manual mode, for the time established for parameter c7.
Steam injection.
The output activity depends mainly on parameter t0.
Through the multifunction input it is also possible to activate the output
in remote mode.
Alarm.
The output is activated during a temperature alarm.
Chamber light.
The output is activated in manual mode.
Cooking timer.
The output is activated during the cooking timer count.
Acoustics.
The output is activated in the following conditions:
• before the conclusion of the cooking timer count (of the time established
with the parameter c9), for the time established with parameter c4
• during an alarm or an error, with continuous contribution.
In spite of the fact that the instrument can manage the
7 utilities stated in this paragraph, there are 3 digital
outputs available. Make sure that the desired utility is
managed by the instrument (see paragraph 2.1).
3 USER INTERFACE
3.1 Preliminary considerations
The following functioning states exist:
• the “on” state (the instrument is powered and on: the regulators can be on)
• the “programmed switch-on” state (the instrument is powered but
switched off via software: the regulators are off and programmed
switch-on of the instrument is envisioned)
• the “stand-by” state (the instrument is powered but switched off via
software: the regulators are off and programmed switch-on of the
instrument is not envisioned)
• the “off” state (the instrument is not powered).
Successively, the term "switch-on" means the passage from the stand-by
state to the on state. The term "switch-off" means the passage from the
on state to the stand-by state.
When powered, the instrument re-proposes the state that it was in when
the power supply was disconnected.

7 STEAM INJECTION
7.1 Preliminary considerations
The functioning mode of the steam injection depends on parameter t0.
If the parameter t0 is set at 0, pressing the key causes the injection of steam for the time established with parameter t2 or for the entire duration that the key is pressed. The parameter t1 establishes the mini-
mum time that can 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: parameter t2 estab-
lishes the duration of the injector switch-on and parameter t1 estab­lishes the duration of switch-off). Using the multifunction input, it is also possible to cause the same effect
by pressing the key in remote mode. If the steam injection is not managed by any digital output, pressing the
key will cause the display of the “no” indication for 1s in the lower
part of the display.

11 ALARMS
11.1 Alarms
CODE MEANING
AL temperature alarm
Remedies:
• check the chamber temperature
• see parameters A1 and A3
Consequences:
• the alarm output will be activated
• the acoustics output and the buzzer output will be activated
PF1 power supply cut-off alarm during cooking timer count
with duration shorter than the time established with param-
eter r13
Remedies:
• press a key to restore the normal display
• check the causes that brought about the power supply
cut-off
Main consequences:
• the count will continue until the instrument is powered
• the acoustics output and the buzzer output will be acti-
vated
PF2 power supply cut-off alarm during cooking timer count
with duration longer than the time established with param-
eter r13
Remedies:
• press a key to restore the normal display
• check the causes that brought about the power supply
cut-off
Main consequences:
• the count will be interrupted
• the acoustics output and the buzzer output will be activated
When the cause of the alarm disappears, the instrument restores nor-
mal functioning, except for the power supply cut-off alarm during the
cooking timer count (codes “PF1” and “PF2”) which requires a key to
be pressed.
12 INTERNAL DIAGNOSTICS
12.1 Internal diagnostics
CODE MEANING
Pr1 chamber probe error
Remedies:
• see parameter P0
• check probe integrity
• check the instrument-probe connection
• check the chamber temperature
Main consequences:
• the temperature regulation output will be deactivated
• the acoustics output and the buzzer output will be activated
rtc clock error
Remedies:
• set the day and real time again
Main consequences:
• the programmed switch-on will not be available
• the acoustics output and the buzzer output will be activated
When the cause of the alarm disappears the instrument restores normal
functioning, except for clock error (code “rtc”) that requires the day
and real time to be set.

13 TECHNICAL DATA
13.1 Technical data
Container: grey self-extinguishing.
Front panel protection rating: IP 54.
Connections: removable terminal boards (power supply, inputs and
outputs), 6-pole connector (serial port). Temperature of use: from 0 to 55 °C (from 32 to 131 °F, 10 ... 90%
relative humidity without condensate).
Power supply: 115 ... 230 VAC, 50/60 Hz, 5 VA (approx) or 24 VAC,
50/60 Hz.
Keeping the clock data in a power-cut: 24 h with battery
charged.
Battery charging time: 2 min without interruptions (the battery is
charged by the instrument power supply).
Alarm buzzer: incorporated.
Measurement inputs: 1 (chamber probe) for J/K thermocouple.
Digital inputs: 1 (multifunction) or NO/NC contact (potential-free
contact, 5 V 1 mA). Range of measurement: from -99 to 800 °C (from-99 to 999 °F) for J thermocouple, from -99 to 999 °C (from -99 to 999 °F) for K thermocouple.
Resolution: 1 °C/1 °F.
Digital outputs: 3 relays:
relay K1: 8 A res. @ 250 VCA (NO contact)
relay K2: 8 A res. @ 250 VCA (NO contact)
relay K3: 8 A res. @ 250 VCA (contact in ex-
change).
The utility managed by each output depends on the instrument code
(see paragraph 2.1).
Other outputs: buzzer output (12 V, max. 20 mA); the output is
activated during alarms and errors, with continuous contribution.
Serial port: port for the communication with the supervising system
(through a serial interface, via TTL, with MODBUS communication pro-
tocol) or with the programming key.

DIGITAL INPUTS
effect caused by the activation of the multifunction input
0 = no effect
1=STAR/INTERRUPTION OF THE COOKING TIMER - the activation of the input will cause the cooking
timer to start and the successive activation will cause its interruption
2=BUZZER, ACOUSTIC OUTPUT AND BUZZER OUTPUT DEACTIVATION - the activation of the input will
cause deactivation of the buzzer, the acoustic output and the buzzer output (activate the input again
to deactivate these utilities again)
3=STEAM INJECTION - in this case:
• if t0 = 0, the activation of the input causes the injection of steam for the time established with
parameter t2 or for the entire duration that the key is pressed (parameter t1 establishes the minimum
time that can pass between the two successive injections) (8)
• if t0 = 1, the activation of the input will enable automatic steam injection (in cyclical mode; param-
eter t2 establishes the duration of the switch-on of the injector and parameter t1 establishes the
duration of switch-off) until the input is activated again (8)

(5) the buzzer and the acoustic output are activated before the conclusion of the cooking timer count (of the time established with the parameter c9),
for the time established with parameter c4
(6) if the cooking timer is interrupted (with the procedure given in paragraph 6.4 or by activation of the malfunction input), the duration of
buzzer activation and of the acoustic output and the flashing duration of the 00:00 indication will be 3 seconds
(7) the parameter differential is 10 °C/18 °F
(8) pressing the key causes the associated effect.
