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 77 %

P28 Pump Speed Used
During Ignition
Defines the minimum pump speed in heating mode during burner ignition

P29 DHW Sensor
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

P30 Fan Speed During
Ignition
This defines the fan speed during burner ignition
Attention:
do not change this parameter

P31 Unit of measurement
This defines the unit of measure on the display, whether metric or Imperial
0 ÷ 127 = °C - kW
128 ÷ 256 = °F -

P32 Min Heating Set Temp Limits the minimum value of the heating set. (The parameter takes priority
in relation to the value set from the pushbutton panel)

P33 Anti-Freeze Activation
Temp
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
Anti-Freeze
Deactivation Flow
Temp
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 Second Boiler Time
Delay On/Off
With its simple cascade operation, it avoids unnecessarily turning the
second boiler on and off
0 ÷ 255 seconds
60 seconds
P36

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