P01 CH Set
This defines the boiler's flow temperature during heating
20 ÷ P02 °C
85
P02 Max CH Set
This defines the maximum settable flow temperature during
heating
20 ÷ 95 °C
85
P03 Heating Hysteresis This defines the power-off hysteresis during the heating phase
2 ÷ 10 °C
5
P04 Anti-cycle CH
This is used to set a waiting time to avoid the boiler from
switching on multiple times and frequently during CH mode
0 ÷ 15 minutes
3 minutes
P05 CH min time
This is the amount of time that the boiler needs to stabilise,
when the burner runs at minimum power for the set amount
of time
3 ÷ 10 minutes
3 minutes
P06 CH ramp
The amount of time that the boiler takes to reach the required
temperature, number of degrees per minute (0 means no
ramp)
0 ÷ 60 °C/minute
4 °C/minute
P07 CH post-
circulation
The amount of CH post circulation once the CH phase is
finished
1 ÷ 30 minutes
3 minutes
P08 Available max
heat out
This defines the maximum power percentage to be used
during the set CH phase
P09 ÷ 100%
100%
P09 Available max
heat out
This defines the minimum power percentage to be used
during the set CH phase
0 ÷ P08%
0%
P10 -
Not used
14 l / minutes
P11 Electrodes anti-
humidity
This defines fan speed and operating mode, to avoid humidity
inside the condensing module, which could otherwise
cause the electrodes to malfunction (0 = disabled function,
recommended value = 40) (RPM speed is calculated by
multiplying the value displayed by 50)
P26

0
P12 P12Boiler’s
modulation ratio
It defines the boiler’s modulation ratio
(Do not modify)
0
÷
100%
10%
P13 Boiler power
Used to calculate the boiler power in the event of simple
cascade.
0
÷
255 kW
80 kW = 75
100 kW = 90
120 kW = 115
P14 External probe
curve
This is used to select the external probe operating curve
(optional) (0 = disabled probe)
0
÷

0
P15 External probe
offset
This defines the CH offset in relation to the selected external
probe curve
20
÷
70 °C
30 °C
P16 DHW set
This defines the DHW temperature
35 ÷ 65 °C
65 °C
P17 External D.H.W /
3-waypump
- With a single boiler it controls an external 3-way.
- With single boiler and common flow probe, it lets you
choose between an external D.H.W pump and a 3-way one.
- With a simple cascade, it manages a D.H.W. pump
(downstream an hydraulic separator).
0 = 3 Ways
1 = D.H.W. pump
P18 DHW hysteresis
This defines the DHW power-on hysteresis during CH
2 ÷ 10 °C
5 °C
P19 DHW post-
circulation
This is the post circulation time during DHW, once DHW
production is finished
0

This defines the maximum power percentage to be used
during the set DHW phase
P21
÷

50 %
P21 Available max
DHW pow
This defines the minimum power percentage to be used
during the set DHW phase
0
÷
P20 %
0 %
P22
DHW flow
temperature with
thermostat
In combination with a storage tank and a separate thermostat,
this defines the flow temperature during DHW operation
35
÷
90 °C
80 °C
P23 DHW modulation
Summed with the “Set San” (P16) parameter, this defines
the flow temperature set that the boiler has to modulate the
power on during DHW
5
÷
30 °C
15 °C
P24 DHW off
increment
This defines the time that the boiler allows the burner to
switch off during DHW, by an increment of 5 °C on top of the
flow temperature
0
÷
255 seconds

P25 Max fan Speed
This defines the max fan speed and therefore the maximum
relative boiler operating power (RPM speed is calculated by
multiplying the value displayed by 50)
