P01 CH Set is denes the boiler's ow temperature during heating 20 ÷ P02 °C 85
P02 Max CH Set
is denes the maximum settable ow temperature during
heating
20 ÷ 95 °C 85
P03 Heating Hysteresis is denes the power-o hysteresis during the heating phase 2 ÷ 10 °C 5
P04 Anti-cycle CH
is 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
is 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
e 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
e amount of CH post circulation once the CH phase is
fnished
1 ÷ 30 minutes 3 minutes
P08
Available max heat
out
is denes the maximum power percentage to be used
during the set CH phase
P09 ÷ 100% 100%
P09
Available max heat
out
is denes 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
is denes 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 ÷120 0
P12
Boiler’s modulation
ratio
It denes 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
is is used to select the external probe operating curve
(optional) (0 = disabled probe)
0 ÷ 10 0
P15 External probe oset
is denes the CH oset in relation to the selected external
probe curve
20 ÷ 70 °C 30 °C
P16 DHW set is denes the DHW temperature 35 ÷ 65 °C 65 °C
P17
P17 External D.H.W /
3-waypump
- With single boiler and common ow 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 is denes the DHW power-on hysteresis during CH 2 ÷ 10 °C 5 °C
P19
DHW post-
circulation
is is the post circulation time during DHW once DHW
production is nished
0 ÷ 180 seconds 60 seconds
P20
Available max DHW
pow
is denes the maximum power percentage to be used
during the set DHW phase
P21 ÷ 100 % 50 %
P21
Available max DHW
pow

during the set DHW phase
0 ÷ P20 % 0 %
P22
DHW ow
temperature with
thermostat
In combination with a storage tank and a separate thermostat,
this denes the ow temperature during DHW operation
35 ÷ 90 °C 80 °C
P23 DHW modulation
Summed with the “Set San” (P16) parameter, this denes the
ow temperature set that the boiler has to modulate the power
on during DHW
5 ÷ 30 °C 15 °C
P24 DHW o increment
is denes the time that the boiler allows the burner to
switch o during DHW, by an increment of 5 °C on top of the
ow temperature
0 ÷ 255 seconds 60 seconds
