Description
0: Instantaneous
1: Instantaneous with flow rate regulator
2: Storage tank
3: Instantaneous with Aquaceleris
The boiler allows the DHW flow rate regulator to be set in
various operating modes:
- Open (0): regulator all open, i.e. maximum possible flow
rate
- 1: 9 l/min
- 2: 12 l/min
- 3: 15 l/min
- Auto (4) : in auto mode the regulator varies the maximum
flow rate to ensure the set domestic hot water temperature.
Defines the maximum operating speed of the pump during
central heating requests (If A1 = A2 pump operating at set
speed).
Defines the minimum pump operating speed during central
heating requests. It is recommended not to enter values
lower than 6
Defines the operating mode of the pump during central
heating requests:
- Δ T = 0: proportional head (Parag. 1.33);
- Δ T = 5 - 25 K: ΔT constant (Parag. 1.33).

-
Establishes the switch-off method in DHW mode.
0 Fixed: the switch-off temperature is fixed at the maximum
value regardless of the value set on the control panel.
1 Correlated: the boiler switches off according to the
temperature set.
Enables the automatic vent function.
This function is activated every time the appliance is
powered again
0: disabled
1: enabled
Selects the system pressure detection mode:
0: Pressure sensor
1: Not used
Value below which fault "E10" (insufficient system pressure)
is signalled, in bar
Value above which the fault "E146" (System pressure too
high) is signalled, in bar
