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 pump operating mode during central heating
requests:
-ΔT=0: proportional head (Parag. 1.32);
-ΔT=5÷25K: ΔT constant (Parag. 1.32).
The temperature value that the board adds to the DHW set
point to determine the cylinder coil flow temperature
The temperature difference compared to the set DHW
set-point which determines the activation of the DHW
priority function
-
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 detected, in bar
Value above which the fault "E146" (System pressure too
high) is detected, in bar
