PARAMETER DESCRIPTION

004

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

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

301

To set the type of hydraulic conﬁ guration for the boiler: 0 = HEATING ONLY - 1 = INSTANTANEOUS FLOW SWITCH - 2 = INSTANTANEOUS FLOW METER -

3 = STORAGE TANK WITH PROBE - 4 = STORAGE TANK WITH THERMOSTAT

Factory value = 2 (do not alter). If the electronic board is replaced, make sure this parameter is set at 2

302

To set the type of water pressure transducer: 0 = water pressure switch - 1 = pressure transducer

Factory value = 1 (do not alter). If the electronic board is replaced, make sure this parameter is set at 1.

303

To enable the “semi-automatic ﬁ lling” function when a pressure transducer and ﬁ lling solenoid valve are installed in the boiler.

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).

310

To modify the heat output in heating mode. Factory value =

309, but it can be programmed within the range 306 - 309.

For more details about the use of this parameter, refer to paragraph “4.12 Range rated”.

311

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= 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

312

Used to reset the operating hours counter in certain conditions (for more details, see “4.13 Faults and reporting”, fault

A91).

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.

313

This parameter allows the regulation of slow ignition in burner re-ignitions following shutdowns due to the set point temperature being reached.

Adjustment is possible between the minimum fan speed value (306) and the speed value during slow ignition (308)

401

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:

SWITCH-OFF TEMPERATURE = HEATING SE 401.

Factory value =

5°C, but it can be set within the range 2 - 10°C.

402

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

ignition: IGNITION TEMPERATURE = HEATING SETPOINT - 402.

Factory value = 5°C, but it can be set within the range 2 - 10°C.

403

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

switch-off: SWITCH-OFF TEMPERATURE = HEATING SE 403.

Factory value = 3°C, but it can be set within the range 2 - 10°C.

404

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

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.

409

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.

The param

eter returns automatically to 0 when the screed heater function ends, but the function can also be interrupted by manually setting the value at 0.

410

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

value = 3 minutes, but it can be se t at a value between 0 and 20 min.

411

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

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.

415

Used to specify the type of area to be heated. Choose from the following options:

0 = HIGH TEMPERATURE (factory setting)

1 = LOW TEMPERATURE

416

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

range 20°C - 45°C, default 45°C for low temperature systems

Note: the value of

416 cannot be lower than 417.

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

range 20°C - 45°C, default 20°C for low temperature systems

Note: the value of

417 cannot be higher than 416.

418

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

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.

419

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

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.
