P4.10
This parameter allows you to change the FORCED HEATING TIMING OFF, regarding the delay
time introduced for re-igniting the burner in the face of an off due to the heating temperature being
reached. The factory setting for this parameter is 3 minutes and can be set to a value between 0
min and 20 min.
P4.11
This parameter allows you to cancel the ANTI CYCLE and REDUCED HEATING MAXIMUM
OUTPUT TIMING, lasting 15 min during which the speed of the fan is limited to 75% of the maximum
heating output that has been set.
The factory setting for this parameter is 0, set 1 to reset the timings.
P4.12
This parameter allows you to configure 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.
Note: this parameter cannot be changed when an OTBus chronothermostat is connected.
P4.13
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.
Note: see the instruction sheet of the BE16 accessory board for more information about the use of
this parameter.
P4.14
When P4.12 = 1, this parameter allows you to set the hydraulic configuration 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.
Note: see the instruction sheet of the BE16 accessory board for more information about the use of
this parameter.

thermoregulation. With an outdoor temperature probe disconnected the boiler always operates at
a fixed point. See paragraph "4.4 Setting the thermoregulation" for more details about this function.
P4.19
This parameter allows you to set the number of the compensation curve used by the boiler when in
thermoregulation. The factory setting for this parameter is 2.0 for high temperature systems and 0.5
for low temperature ones. The parameter can be set with the range 1.0 - 3.0 for high temperature
systems, 0.2 - 0.8 for low temperature ones.
See paragraph "4.4 Setting the thermoregulation" for more details about this function.
P4.20

P4.21
The factory setting for this parameter is 0. Do not change.
P4.22
Do not change this parameter.
P4.23
This parameter allows you to activate the management of an additional heating zone (the use of the
BE16 accessory board is required, not supplied as standard).

factory setting is 1 and can be set within the 1 - 6 range.
Note: see the instruction sheet of the BE16 accessory board for more information about the use of
this parameter.
P4.25

factory setting for this parameter is 0 and allows you to manage a direct zone, set to 1 to manage
a mixed zone.
Note: see the instruction sheet of the BE16 accessory board for more information about the use of
this parameter.
P4.26
When P4.12 = 1 this parameter allows you to specify the type of zone to be heated. It is possible to
choose from the following options:
0 = HIGH TEMPERATURE (factory setting)
1 = LOW TEMPERATURE
P4.27
When P4.12 = 1, this parameter allows you to the setpoint value of heating zone 1. The factory
setting for this parameter is P4.28 and can be programmed within the P4.29 and P4.28 range.
P4.28
This parameter allows you to specify the maximum heating setpoint that can be set for zone 1:
- 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 P4.28 value cannot be less than P4.29.
P4.29
This parameter allows you to specify the minimum heating setpoint that can be set for zone 1:

P4.30
This parameter allows you to activate thermoregulation mode for zone 1 when the system has an
outdoor temperature sensor connected. The factory setting is 0, the boiler always operates for zone 1
at a fixed point; to have the boiler work in climate mode connect an outdoor temperature sensor and
set the parameter to 1, connect an outdoor temperature sensor. With an outdoor temperature probe
disconnected the boiler always operates at a fixed point.

P5 (DHW menu)
P5.10
This parameter allows you to set the delayed starting of the boiler in domestic hot water mode.
The factory setting for this parameter is 0 and can be programmed within the range 0 - 60sec.
P5.11
This parameter allows you to activate the following functions related to the operation of the boiler in
domestic hot water mode:
0 = no function; the boiler in domestic hot water mode starts immediately and uses the related
domestic hot water thermostats, i.e. it switches off at setpoint +5°C and switches back on at
setpoint +4°C (factory setting)
1 = domestic hot water delay function, so the boiler in domestic hot water mode starts with a delay
equal to the value of the parameter P5.10
2 = FUNCTION NOT AVAILABLE ON THIS MODEL
3 = the boiler uses absolute domestic hot water thermostats, i.e. in domestic hot water mode it
always switches off at 65°C and switches back on at 63°C, independently of the domestic hot
water setpoint that has been set
4 = functions 1 and 3 are active
P8 (CONNECTIVITY menu)
P8.01
This parameter is used to manage the boiler remotely. Three values are available for this pa-
rameter:
0 = FACTORY-SET VALUE. The interface on the machine is operational but the boiler can
also be controlled remotely if the Modbus device for WiFi/Bluetooth connection is attached
to the connector under the shelf (optional accessory, not supplied as standard)
1 = remote boiler control is disabled, only the interface on the machine is operative. If con-
nected, the Modbus device for WiFi/Bluetooth connection is ignored, while a connection
error is generated when connecting a Modbus remote control (REC10) and the error
<<COM>> is shown
2 = you can connect a Modbus remote control (REC10) to control the boiler; the interface on
the machine is disabled and <<RCTR>> is shown on the display. Only the MENU button
for changing parameter P8.01 remains active.
P8.03
This parameter is used to enable remote boiler management using an OpenTerm device:
0 = With the OT+ function disabled, you cannot control the boiler remotely using an OT+
device. If this parameter is set to 0, any OT+ connection is instantly interrupted, and the
"xx" icon and "OTB" message on the display are switched off
1 = FACTORY-SET VALUE. With the OT+ function enabled, you can connect an OT+ device
to control the boiler remotely. When you connect an OT+ device to the boiler, the "xx" icon
lights up on the display and "OTB" appears.
