If the pressure acquired via input H1, H2 (EM1...EM3) or H3 drops below the limit value
set here, the respective error message is delivered and the burner is immediately shut
down.

When the water pressure drops, falling below the limit value by the switching
differential, the error message is canceled.
If the water pressure rises, exceeding the limit value by the switching differential, the
error message is canceled.
If the water pressure rises, exceeding the limit value by the switching differential, the
error message is canceled.
Note!
If, with 2 or 3 extension modules, water pressure supervision at H2 is activated, all
inputs H2 use the same parameter values. The error message with the highest
priority is displayed.
The water pressure is displayed in the Info menu.
This is the value of the first input within the following sequence with a pressure
measurement assigned to it: H1, H2 EM1, H2 EM2, H2 EM3, H3.
