P26 Min fan Speed
This defines the min fan speed and therefore the minimum
relative boiler operating power (RPM speed is calculated by
multiplying the value displayed by 50)

P27 Min pump speed Defines the minimum pump speed in heating mode at the
minimum boiler power.
Attention
: do not go below 30%

P28
Pump speed
during burner
ignition
Defines the minimum pump speed in heating mode when the
burner turns on
Attention
: do not go below 40%
1 ÷ 100 %

P29 DHW
configuration
This is used to select the DHW operating mode, choosing
between NTC probe or on/off thermostat
1 = NTC probe
17 = on/off
thermostat

This defines the fan speed during burner ignition
Attention:
do not change this parameter (RPM speed is
calculated by multiplying the value displayed by 50)

P31 Unit of
measurement
This defines the unit of measure on the display, whether
metric or Imperial
0 ÷ 127 = °C - kW

0
P32 Set Resc Min
Limits the minimum value of the heating set. (The parameter
takes priority in relation to the value set from the pushbutton
panel)
P33
Antifreeze
function activated
by the common
flow probe
It activates the antifreeze function launched by the common
flow probe. The boiler turns on once there is a drop below the
set value
2 ÷ 20 °C
5°C
P34
Antifreeze
function
deactivated by
the common flow
probe
It deactivates the antifreeze function launched by the
common flow probe. The boiler turns off once the set
temperature is reached
2 ÷ 20 °C
15°C
P35
Delayed
Activation /
Deactivation of
the second boiler
With its simple cascade operation, it avoids unnecessarily
turning the second boiler on and off
0 ÷ 255 seconds

P37 0 ÷ 10 V inlet
It defines whether the boiler must function with the
temperature or probe set0 = temperature set
1 = power set
P38
Common
flow probe
configuration
It activates the common flow probe functioning
0 = no probe
1 = probe present
