Pressure measurement
The voltage signal active at input H1 is converted to a pressure value in a linear
manner.
The pressure value at 0.5 V is fixed at 0 bar.
The pressure value at 3.5 V can be adjusted using parameter "Pressure value 3.5 V
H1" (line 5956).
NC
The contact is normally closed and must be opened to activate the selected function.
NO
The contact is normally open and must be closed to activate the selected function.
Function "Min flow temp setpoint" on operating line 5950 is activated via contact H1.
The boiler maintains the temperature level set here until contact H1 opens again or until
a higher heat request is delivered.
If several heat requests are received at the same time (LPB, contact H1, DHW, or from
the controller itself), the highest of them will automatically be selected.

TVw Flow temperature setpoint
The voltage signal present at input H1/H2 is converted to a temperature value in a
linear manner and then forwarded as the flow temperature setpoint.
The flow temperature setpoint corresponding to the voltage level of 10 V can be
adjusted with parameter "Heat request 10V H1/H2".
