P01
Set Risc (CH Set) is denes the boiler's ow temperature during heating 20 ÷ P02 °C 85
P02
Set risc Max (Max
CH Set)
is denes the maximum settable ow temperature during heating 20 ÷ 95 °C 85
P03

riscaldamento
(Heating Hysteresis)
is denes the power-o hysteresis during the heating phase 2 ÷ 10 °C 5
P04
Anti cicli
riscaldamento (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
Tempo min risc (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
Rampa
riscaldamento (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
Post circolazione
riscaldamento (CH
post-circulation)
e amount of CH post circulation once the CH phase is fnished 1 ÷ 30 minutes 3 minutes
P08
Pot risc max
disponibile (Available
max heat out)
is denes the maximum power percentage to be used during the set CH
phase
P09 ÷ 100% 100%
P09
Pot risc min
disponibile (Available
max heat out)
is denes the minimum power percentage to be used during the set CH
phase
0 ÷ P08% 0%
P10
Minimum system
ow rate
is denes the minimum system ow rate required to power-on the boiler
Attention: do not change this parameter
5 ÷ 47 l/minutes 14 l/minutes
P11
Anti umidità elettrodi
(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
35 kW = 35
55 kW = 50
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
Set San (DHW set) is denes the DHW temperature 20 ÷ 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
Isteresi sanitario
(DHW hysteresis)
is denes the DHW power-on hysteresis during CH 2 ÷ 10 °C 5 °C
P19
Post circolazione
sanitario (DHW post-
circulation)
is is the post circulation time during DHW once DHW production is
nished
0 ÷ 180 seconds 60 seconds
P20
Pot san max
disponibile (Available
max DHW pow)
is denes the maximum power percentage to be used during the set DHW
phase
P21 ÷ 100 % 50 %
P21
Pot san min
disponibile (Available
max DHW pow)
is denes the minimum power percentage to be used 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
Modulazione sanitario
(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
Incremento o
sanitario (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
P25
Velocità Max
ventilatore (Min fan
Speed)
is denes the max fan speed and therefore the maximum relative boiler
operating power (RPM speed is calculated by multiplying the value displayed
by 50)
P26 ÷ 255 RPM x 50
35 kW Met. 101
35 kW LPG 98
55 kW Met. 131
