Each time that the boiler is powered a vent cycle is carried out
lasting 4 min. The display shows the message -AIR lighting up
the icon RESET.
To interrupt the vent cycle press RESET.
Set the boiler to OFF by pressing

BOILER CONFIGURATION
To access the boiler configuration menu, access the technical parameters
menu, as indicated in the paragraph "5.1 Access to the parameters" .
Use the
and
arrows to scroll through the parameters of the pre-
selected sub-menu, confirming the selection with A; change the value of the
pre-selected parameter with C and D confirming the selection with the key
indicated by the icon
.

Description of the settings menu
Some of the following functions might not be available depending on the
access level and the type of machine.
P1 (SETTINGS menu)
P1.01
Select the parameter to set the desired language (see the tree-view
menu in paragraph "5.3 SETTINGS MENU TREE STRUCTURE" ).
P1.02
From this menu the time and the number of the day of the week can be
adjusted.
P1.03
P1.05
This parameter allows you to enable scrolling text after the parameter
code itself:
0= OFF
1= ON
P3 (CONFIGURATION menu)
P3.01
This parameter allows you to set the type of hydraulic configuration of the
boiler:
0 = ONLY HEATING
1 = INSTANTANEOUS FLOWSWITCH
2 = INSTANTANEOUS FLOWMETER
3 = STORAGE CYLINDER WITH PROBE
4 = STORAGE CYLINDER WITH THERMOSTAT
The factory setting for this parameter is 0. When replacing the electronic
board make sure that this parameter is set to 0.
P3.02
This parameter allows you to set the type of water pressure transducer:
0 = water pressure switch
1 = pressure transducer
The factory setting for this parameter is 1 do not change! When replacing the
electronic board make sure that this parameter is set to 1.
P3.03
This parameter allows you to enable the "semi-automatic filling" function
since the boilers have a pressure transducer and a filling solenoid valve
installed.
The factory setting for this parameter is 0, do not change! When replacing
the electronic board make sure that this parameter is set to 0.
P3.04
This only appears if P3.03=1. NOT AVAILABLE ON THIS MODEL
P3.05
This parameter allows you to disable the vent cycle function; the factory
setting is 1, set the parameter to 0 to disable the function.
26
.
P3.06
This parameter allows you to change the minimum number of the fan's rpm.
P3.07
This parameter allows you to change the maximum number of the fan's rpm.
P3.08
This parameter allows you to change the soft ignition value.
P3.09
This parameter allows you to change the maximum number of the fan's rpm in heating mode.
Do not change!
P3.10
This parameter allows you to change the heat output in heating mode, the factory setting for
this parameter is P3.09 and can be programmed within the P3.06 - P3.09 range.
For more information about the use of this parameter see the paragraph "8.12 Range rated".
P3.11
This parameter allows you to configure the operation of an additional relay (only if the relay
board is installed (not supplied as standard)) to bring a phase (230Vac) to a second heating
pump (additional pump) or a zone valve. The factory setting for this parameter is 0 and can
be set within the 0 - 2 range with the following meaning:
Pin 1 and 2 of X21
Not present
P3.11 = 0
additional pump management zone valve management
P3.11 = 1
zone valve management
P3.11 = 2
additional pump management additional pump management
P3.12
This parameter allows operating hours meter to be reset in certain conditions (see "8.14
Lights and faults" for more information, E091 faults). The factory setting for this parameter
is 0, set to 1 to reset the flue gas probe hours meter after the primary heat exchanger has
been cleaned.
Once the reset procedure is finished, the parameter returns automatically to 0.
P4 (HEATING menu)
P4.01
For high temperature systems, this parameter allows you to set the hysteresis value used
by the adjustment board for calculating the switching off delivery temperature of the burner:
SWITCHING OFF TEMPERATURE = HEATING SETPOINT + P4.01.
The factory setting for this parameter is 5°C, it can be changed within the 2 - 10°C range.
P4.02
For high temperature systems, this parameter allows you to set the hysteresis value used by
the adjustment board for calculating the ignition delivery temperature of the burner:
IGNITION TEMPERATURE = HEATING SETPOINT - P4.02.
The factory setting for this parameter is 5°C, it can be changed within the 2 - 10°C range.
P4.03
For low temperature systems, this parameter allows you to set the hysteresis value used
by the adjustment board for calculating the switching off delivery temperature of the burner:
SWITCHING OFF TEMPERATURE = HEATING SETPOINT + P4.03.
The factory setting for this parameter is 3°C, it can be changed within the 2 - 10°C range.
P4.04
For low temperature systems, this parameter allows you to set the hysteresis value used by
the adjustment board for calculating the ignition delivery temperature of the burner:
IGNITION TEMPERATURE = HEATING SETPOINT - P4.04.
The factory setting for this parameter is 3°C, it can be changed within the 2 - 10°C range.
P4.05
Not used on this model.
P4.08
This parameter allows you to set the boiler for cascade applications via an OTBus si-
gnal. Not applicable to this model of boiler.
P4.09
Not available on this model.
P4.10
This parameter allows you to change the FORCED HEATING TIMING OFF, regarding
the delay time introduced for re-igniting the burner in the face of an off due to the heating
temperature being reached. The factory setting for this parameter is 3 minutes and can be
set to a value between 0 min and 20 min.
P4.11
This parameter allows you to cancel the ANTI CYCLE and REDUCED HEATING MAXIMUM
OUTPUT TIMING, lasting 15 min during which the speed of the fan is limited to 75% of the
maximum heating output that has been set.
The factory setting for this parameter is 0, set 1 to reset the timings.
P4.12
This parameter allows you to configure the system to manage a mixing valve and an
additional pump on the main heating system (the use of the BE16 accessory board is
required, not supplied as standard). The factory setting for this parameter is 0, set to 1 for the
connection of a BE16 board.
Note: this parameter cannot be changed when an OTBus chronothermostat is connected.
