P04 Heating Anti-Cycle
Time
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

P05 Burner Stabilization
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 Heating Temp Rise
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 Heating Pump
Overrun Time
The amount of CH post circulation once the CH phase is fnished
1 ÷ 30 minutes

P08
Boiler Power Used
During Max Heating
Mode
This defines the maximum power percentage to be used during the set CH
phase
P09 ÷ 100%
100%
P09
Boiler Power Used
During Min Heating
Mode
This defines the minimum power percentage to be used during the set CH
phase
0 ÷ P08%
0%
P10 Minimum system
flow rate
This defines the minimum system flow rate required to power-on the boiler
Attention:
do not change this parameter

14 l/minutes
P11 Electrode Anti-
Humidity Fan Speed
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 Boiler’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.

P14 External probe curve
This is used to select the external probe operating curve (optional) (0 =
disabled probe)
0

P15 External probe offset
This defines the CH offset in relation to the selected external probe curve
20

P16 DHW Set Temp
This defines the DHW temperature
20 ÷ 65 °C
65 °C
P17 DHW Configuration
- 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
0
P18 DHW Hysteresis
This defines the DHW power-on hysteresis during CH
2 ÷ 10 °C

Time
This is the post circulation time during DHW once DHW production is
finished

Boiler Power Used
During Min DHW
Mode
This defines the minimum power percentage to be used during the set DHW
phase

P22 Flow Delivery Temp
During DHW Mode
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

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

P25 Max Fan Speed
This defines the max fan speed and therefore the maximum relative boiler
operating power
