Parameters description
Some of the following functions may not be available depending on the machine type and access level.
PARAMETER DESCRIPTION
To alter the measurement unit: 0 = METRIC measurement units / 1 = IMPERIAL measurement units. The fi gures are expressed in decimal format (one fi gure) for values
004
between -9°C and +99°C, and in whole number format for values ≤ -10°C and ≥ 100°C. The visualisation in °F (Fahrenheit) is always expressed in whole number format.
006
To enable/disable the acoustic signal, 0 = buzzer OFF / 1 = buzzer ON
To set the type of hydraulic confi guration for the boiler: 0 = HEATING ONLY - 1 = INSTANTANEOUS FLOW SWITCH - 2 = INSTANTANEOUS FLOW METER -
301
3 = STORAGE TANK WITH PROBE - 4 = STORAGE TANK WITH THERMOSTAT
Factory value = 1 (do not alter). If the electronic board is replaced, make sure this parameter is set at 1
To set the type of water pressure transducer: 0 = water pressure switch - 1 = pressure transducer
302
Factory value = 1 (do not alter). If the electronic board is replaced, make sure this parameter is set at 1.
To enable the "semi-automatic fi lling" function when a pressure transducer and fi lling solenoid valve are installed in the boiler.
303
Factory value = 0 (do not alter). If the electronic board is replaced, make sure this parameter is set at 0.
304
Only appears if 303 = 1 NOT AVAILABLE ON THIS MODEL.
305
To disable the vent cycle function. Factory value = 1. Set the parameter at 0 to disable the function.
306
To alter the minimum number of fan rotations.
307
To alter the maximum number of fan rotations.
308
To regulate slow ignition (it can be programmed within the range 306 - 307).
309
To alter the maximum fan rpm in heating mode (it can be programmed within the range 306 - 307).
To modify the heat output in heating mode. Factory value = 309, but it can be programmed within the range 306 - 309.
310
For more details about the use of this parameter, refer to paragraph "4.12 Range rated".
To confi gure the operation of a supplementary relay (only if board BE09 (accessory kit) is installed) in order to bring a phase (230V AC) to a second heating pump
(supplementary pump) or to a zone valve. Factory value = 0, but it can be programmed within the range 0 - 2 with the following meaning:
311
311= 0 - control depends on the confi guration of the wiring of the BE09 board (jumper cut: supplementary pump - jumper present: zone valve)
311= 1 - control of the zone valve
311= 2 - control of the supplementary pump
Used to reset the operating hours counter in certain conditions (for more details, see "4.13 Faults and reporting", fault A91).
312
Factory value = 0. Bring the value to 1 to reset the fl ue gas probe hour counter after the cleaning of the primary heat exchanger.
When the reset procedure has been completed, the parameter will return automatically to 0.
This parameter allows the regulation of slow ignition in burner re-ignitions following shutdowns due to the set point temperature being reached.
313
Adjustment is possible between the minimum fan speed value (306) and the speed value during slow ignition (308)
For high temperature systems, this parameter allows the setting of the hysteresis value used by the adjustment board to calculate the delivery temperature for burner switch-off:
401
SWITCH-OFF TEMPERATURE = HEATING SETPOINT + 401. Factory value = 5°C, but it can be set within the range 2 - 10°C.
For high temperature systems, this parameter allows the setting of the hysteresis value used by the adjustment board to calculate the delivery temperature for burner
402
ignition: IGNITION TEMPERATURE = HEATING SETPOINT - 402. Factory value = 5°C, but it can be set within the range 2 - 10°C.
For low temperature systems, this parameter allows the setting of the hysteresis value used by the adjustment board to calculate the delivery temperature for burner
403
switch-off: SWITCH-OFF TEMPERATURE = HEATING SETPOINT + 403.
Factory value = 3°C, but it can be set within the range 2 - 10°C.
For low temperature systems, this parameter allows the setting of the hysteresis value used by the adjustment board to calculate the delivery temperature for burner
404
ignition: IGNITION TEMPERATURE = HEATING SETPOINT - 404.
Factory value = 3°C, but it can be set within the range 2 - 10°C.
405
Pump with variable proportional speed. NOT AVAILABLE ON THIS MODEL.
408
Used to set the boiler for cascade applications via an OT+ signal. Not applicable with this boiler model.
Used to activate the screed heater function (for more details, refer to paragraph "4.7 Screed heater function").
Factory value = 0, with the boiler OFF. Set the value at 1 to activate the screed heater function on the low temperature heating areas.
409
The parameter returns automatically to 0 when the screed heater function ends, but the function can also be interrupted by manually setting the value at 0.
Used to modify the forced heating off timer with regards the delay time for re-igniting the burner if it is OFF because the heating temperature has been reached. Factory
410
value = 3 minutes, but it can be se t at a value between 0 and 20 min.
Used to annul the HEAT TIME RESET function and REDUCED MAX. HEATING OUTPUT TIMER, during which the fan speed is limited to a range between the minimum
411
and 60% of the max. heating output set, with a 10% increase every 15 minutes. Factory value = 0. Set at 1 to reset the timer.
Used to specify the type of area to be heated. Choose from the following options:
415
0 = HIGH TEMPERATURE (factory setting)
1 = LOW TEMPERATURE
Used to specify the maximum heating setpoint value that can be set:
range 20°C - 80.5°C, default 80.5°C for high temperature systems
416
range 20°C - 45°C, default 45°C for low temperature systems
Note: the value of 416 cannot be lower than 417.
This parameter is used to specify the minimum heating setpoint value that can be set:
range 20°C - 80.5°C, default 40°C for high temperature systems
417
range 20°C - 45°C, default 20°C for low temperature systems
Note: the value of 417 cannot be higher than 416.
Used to activate temperature control when the system is connected to an outdoor temperature sensor.
Factory value = 0 (the boiler always works with a fi xed point). If the parameter is set at 1 and an outdoor temperature sensor is connected, the boiler works in temperature
418
control mode. If the outdoor temperature sensor is disconnected, the boiler always works with a fi xed point.
See paragraph "4.4 Setting the thermoregulation" for more details about this function.
Used to set the number of the compensation bend used by the boiler in temperature control mode. Factory value = 2.0 for high temperature systems, and 0.5 for low
419
temperature systems. The parameter can be programmed within the range 1.0 - 3.0 for high temperature systems, or 0.2 - 0.8 for low temperature systems. See para-
graph "4.4 Setting the thermoregulation" for more details about this function.
