1 = LPG
P2.02
Set this parameter for the type of boiler, see the relative paragraph "4.26 Replacing the board" for
more information.
P2.03
This parameter allows you to reset the factory settings of the combustion, see the relative paragraph
"4.27 Combustion Control Parameters" for more information.
P2.04
NOT AVAILABLE ON THIS MODEL
P2.06
This function is used by the Technical Assistance Centre to automatically calibrate the machine
when the CO2 values (shown in the technical data) are out of range.
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.
14
.
Enter
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.
P3.06
This parameter allows you to change the minimum number of the fan's rpm. Do not change!
P3.07
This parameter allows you to change the maximum number of the fan's rpm. Do not change!
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 "4.18 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
P3.11 = 0
P3.11 = 1
P3.11 = 2
P3.12
This parameter allows operating hours meter to be reset in certain conditions (see "4.19 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
P90 = 0 exceptional use of a UPS circulator
P90 = 1 Pump at maximum fixed speed (as if it were ON-OFF)
2 ≤ P90 ≤ 40
41 ≤ P90 ≤ 100
For details see paragraph "3.11 Variable speed circulator".
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 paragraph "4.14 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.
