Note
To avoid operating the heating
installation with an insufficient
water volume and to prevent po-
tential subsequent damage, the
product is fitted with a pressure
sensor. The pressure sensor
signals the low pressure level if
the level falls below 0.06 MPa
(0.6 bar). This is signalled by
the system pressure value in
the display flashing. If the level
falls below 0.03 MPa (0.3 bar),
the system displays the fault
message and
F.22 alternately,
and the burner is blocked. If
the system pressure is lower
than 0.06 MPa (0.6 bar), fill the
heating installation up again as
quickly as possible. As soon as
the system pressure exceeds
0.06 MPa (0.6 bar), the product
starts up without any further
measures being required.
If the pressure sensor is defect-
ive, the product enters com-
fort safety mode. The max-
imum possible flow temperat-
ure and the power are limited.
The status
S.40 and F.22 (water
deficiency) are displayed altern-
ately.
Note
If the heating installation ex-
tends over several floors, a
higher system pressure for the
heating installation may be ne-
cessary. Ask your competent
person for details.
4.1.5 Filling the heating installation
Caution.
Risk of material damage due
to heating water that is ex-
tremely calciferous or corros-
ive or contaminated by chem-
icals.
Unsuitable tap water damages
the seals and diaphragms,
blocks components in the
product and heating installation
through which the water flows
and causes noise.
▶
Only fill the heating install-
ation with suitable heating
water.
▶
In case of doubt, ask a com-
petent person for details.
1. Ask a competent person where the
filling cock is located.
2. Connect the filling tap to a heating wa-
ter supply in the way you were told by
the competent person.
3. Open all radiator valves (thermostatic
radiator valves) of the heating installa-
tion.
4. Open the heating water supply.
5. Slowly open the filling cock.
6. Fill it with water until the required filling
pressure is reached.
7. Close the filling cock.
8. Purge all radiators.
9. Then check the filling pressure on the
display.
10. Top up with more water if necessary.
11. Close the filling tap and the heating
water supply.
