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.
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 “8.11 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
Jumpered
P3.11 = 0
additional pump management zone valve management
P3.11 = 1

P3.12
This parameter allows operating hours meter to be reset in certain conditions
(see “8.13 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 SE 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 SE 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 signal. Not applicable to this model of boiler.
P4.09
This parameter allows you to activate the screed heater function (see “5.8.11
Screed heating function” for more details). The factory setting is 0, with the
boiler set to OFF, set to 1 to activate the screed heater function on the low
temperature heating zones. The parameter automatically returns to 0 once
the screed heater function is finished, it is possible to interrupt it earlier by
setting the value to 0.
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 .
5.5 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
Enter
.
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
“
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
This parameter allows you to set the time programm, only if the clock is
enabled.
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 1. When replacing the electronic
board make sure that this parameter is set to 1.
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
