6.2 Description of the parameters
PARAMETER DESCRIPTION
P101 To set the desired language:
P102 To set TIME AND DAY
P103 To set the TIME SCHEDULE
To change the unit of measurement: 0 = unit of measurement METRIC / 1 = unit of measurement IMPERIAL. The digits are expressed in decimal format (one digit) for values
P104
P105 To set the scrolling text: 0 = disabled / 1 = enabled
P106 To enable/disable sound indicators: 0 = buzzer OFF / 1 = buzzer ON
P201
P208 This parameter is used to set the boiler output: 0=25kW - 1=35kW
P205 This parameter is used to reset the P1 value of the gas valve
P206 This parameter is used to calibrate the gas valve and combustion control system
P301 3 = STORAGE CYLINDER WITH PROBE - 4 = STORAGE CYLINDER WITH THERMOSTAT
Factory setting = 2, do not modify. When replacing the circuit board, ensure that this parameter is set to 2
To set the water pressure transducer type: 0 = water pressure switch - 1 = pressure transducer
P302
Factory setting = 1, do not modify. When replacing the circuit board, make sure this parameter is set to 1.
P303
Factory setting = 0, do not modify. When replacing the circuit board, make sure this parameter is set to 0.
P304 It only appears if P303 = 1. NOT AVAILABLE ON THIS MODEL.
P305 To disable the vent cycle function. Factory setting = 1, set the parameter to 0 to disable the function.
P306 To vary the minimum fan speed.
P307 To vary the maximum fan speed.
P309 To vary the maximum heating fan speed (can be programmed within the range P306 - P307).
P310 RANGE RATED adjustment. DO NOT CHANGE.
valve. Factory setting = 0 and can be programmed within the range 0 - 2 with the following meaning:
P311
P311= 1 - zone valve management
P311= 2 - additional pump management
Allows the operating hours counter to be reset under certain conditions (see "Signalling and faults" fault E091 for details).
P312
Once the resetting procedure is complete, the parameter automatically returns to the value 0.
P401 TEMPERATURE = HEATING SETPOINT + P401.
Factory value = 5°C, can be changed in the range 2 - 10°C.
P402 PERATURE = HEATING SETPOINT - P402.
Factory value = 5°C, can be changed in the range 2 - 10 °C.
P403 TEMPERATURE = HEATING SETPOINT+ P403.
Factory setting = 3 °C, can be changed in the range 2 °C- 10 °C.
P404 PERATURE = HEATING SETPOINT - P404.
Factory setting = 3 °C, can be changed in the range 2°C- 10 °C.
P405 Proportional variable speed pump.
P408 Allows the boiler to be set up for cascade applications via OT+ signal. Not applicable to this boiler model.
Allows you to activate the seat-warming function (see section "Screed heater function" for more details).
P409
The para
Allows you to change the forced heating off timing, which relates to the delay time introduced for the re-ignition of the burner when the burner is switched off due to reaching the
P410
heating temperature. Factory setting = 3 minutes and can be set to a value between 0 min and 20 min.
Allows you to cancel the function HEATING RESET TIMING and REDUCED HEATING MAXIMUM OUTPUT, during which the fan speed is limited between the minimum value and
P411 60% of the set maximum heating power, with an increase of 10% every 15 minutes.
Factory setting = 0, set to 1 to reset timings.
Allows you to specify the type of zone to be heated, choosing from the following options:
P415
Lets you specify the maximum heating setpoint value that can be set:
P416
Note: The value of P416 cannot be less than P417.
With this parameter you have the possibility of specifying the minimum settable heating setpoint:
P417
Note: The value of P417 cannot be greater than P416.
Enables thermoregulation when an outdoor temperature sensor is connected to the system.
P418
See "Setting the thermoregulation" for more details on this function.
Allows you to set the number of the compensation curve used by the boiler when in temperature control. Factory value = 2.0 for high temperature systems and 0.5 for low temper-
P419 ature systems. The parameter can be programmed in the range 1.0 - 3.0 for high temperature systems, 0.2 - 0.8 for low temperature systems. See "Setting the thermoregulation"
for more details on this function.
Activates the 'night compensation' function. Default value = 0, set to 1 to activate the function.
P420
See "Setting the thermoregulation" for further information on this function.
This parameter enables heating time programming.
P421 Time programming not enabled = 0
Time programming enabled = 1
This parameter is used to set the mode for switching from manual to automatic heating operation.
P422 Default value = 0: switching from manual to automatic time programming must be done by the user by pressing the buttons C+D.
P433
P434 Reading interval of the outdoor temperature value read by the probe.
2=LPG
When the room thermostat contact is closed, the heat request is enabled according to the set time programming.
