P1.09
To set the type of hydraulic confi guration of the boiler: 0 = HEATING ONLY - 1 = INSTANTANEOUS FLOW SWITCH - 2 = INSTANTANEOUS FLOW METER -
P3.01
3 = STORAGE TANK WITH PROBE - 4 = STORAGE TANK WITH THERMOSTAT
Factory value = 0. If the electronic board is replaced, make sure this parameter is set at 0

P3.09
To modify the heat output in heating mode. NOT AVAILABLE ON THIS MODEL.
P3.10
To configure 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:
P3.11= 0 - control depends on the confi guration of the wiring of the BE09 board (jumper cut: supplementary pump - jumper present: zone valve).
P3.11
P3.11= 1 - control of the zone valve
P3.11= 2 - control of the supplementary pump
Used to reset the operating hours counter in certain conditions (for more details, see Faults and reporting", fault E091).
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.
P3.12
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. Adjustment is possible
P3.13
between the minimum fan speed value (P3.06) and the speed value during slow ignition (P3.08).
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 SETPOINT + P4.01.
P4.01
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
ignition: IGNITION TEMPERATURE = HEATING SETPOINT - P4.02.
P4.02
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
switch-off: SWITCH-OFF TEMPERATURE = HEATING SETPOINT + P4.03.
P4.03
Factory value = 3°C, but it can be set within the range 2 °C- 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
ignition: IGNITION TEMPERATURE = HEATING SETPOINT - P4.04.
P4.04
Factory value = 3°C, but it can be set within the range 2°C - 10°C.
The speed of the pump is PROPORTIONAL to that of the fan and in DHW it is always at max. The parameter can be set in the range 60-100
P4.05
100= no modulation - 60 = max modulation - 85= default value
P4.08
Used to set the boiler for cascade applications via an OT+ signal.
Used to activate the screed heater function (for more details, refer to paragraph 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.
P4.09
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
P4.10
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
P4.11
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.
This parameter allows you to confi gure the system to manage a mixing valve and an additional pump on the main heating system (the use of the BE16 accessory board
is required, not supplied as standard). The factory setting for this parameter is 0, set to 1 for the connection of a BE16 board.
P4.12
Note: this parameter cannot be changed when an OT+ chronothermostat is connected.
When P4.12 = 1, this parameter allows you to set the address of the BE16 board.
The factory setting for this parameter is 3 and can be set within the 1 - 6 range.
P4.13
Note: see the instruction sheet of the BE16 accessory board for more information about the use of this parameter.
When P4.12 = 1, this parameter allows you to set the hydraulic confi guration of the main heating zone. The factory setting for this parameter is 0 and allows a direct zone
to be managed, set the parameter to 1 for the management of a mixed zone.
P4.14
Note: see the instruction sheet of the BE16 accessory board for more information about the use of this parameter.
Used to specify the type of area to be heated. Choose from the following options:
0 = HIGH TEMPERATURE (factory setting)
P4.15
1 = LOW TEMPERATURE
Used to specify the maximum heating setpoint value that can be set:
range 20°C - 80°C, default 80.5°C for high temperature systems
P4.16
range 20°C - 45°C, default 45°C for low temperature systems.
Note: the value of P4.16 cannot be lower than P4.17.
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
P4.17
range 20°C - 45°C, default 20°C for low temperature systems
Note: the value of P4.17 cannot be higher than P4.16.
Used to activate temperature control when the system is connected to an outdoor temperature sensor. Factory value = 0, the boiler always works with a fixed 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,
P4.18
the boiler always works with a fixed point.
See paragraph "Setting the thermoregulation" for more details about this function.
Used to set the number of the compensation curve 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-
P4.19
graph "Setting the thermoregulation" for more details about this function.
Activates the "night-time compensation" function.
P4.20
The default value is 0. Set at 1 to activate the function. See paragraph "Setting the thermoregulation" for more details about this function.
Do not modify
P4.21- P4.22
This parameter allows you to activate the management of an additional heating zone (the use of the BE09 accessory board is required, not supplied as standard).
The default value is 0, set to 1 to activate the function.
