4.12 Guaranteeing the correct
filling pressure of the heating
system
4.12.1 Checking the filling pressure
of the heating installation
Note
To ensure that the heating installa-
tion operates smoothly, the filling
pressure when the heating install-
ation is cold must be between
0.10 MPa and 0.20 MPa (1.0 bar
and 2.0 bar) or lie between the
two dashed lines in the bar graph
display.
If the heating installation extends
over several storeys, a higher filling
pressure may be required for the
heating installation. Ask a compet-
ent person for details.
In addition, the
symbol appears
after approx. one minute.
If the filling pressure in the heating
installation falls below 0.05 MPa
(0.5 bar), then the product switches
off. The display alternates between
the fault message
F.22
and the
current filling pressure.
1. Press
twice.
◁
The values for the current filling
pressure and for the minimum and
maximum filling pressures appear in
the display.
2. Check the filling pressure in the
display.
1 / 2
System pressure: 0.10 … 0.20 MPa
(1.00 … 2.00 bar)
The filling pressure is in the intended
pressure range.
2 / 2
Filling pressure: < 0.08 MPa
(< 0.80 bar)
