Avoiding danger arising from insufficient
water pressure
The filling pressure must be between 0.10 and 0.15 MPa
(1.0 and 1.5 bar).
If the heating installation extends over several storeys,
higher filling pressures may be required to avoid air entering
the heating installation.
If the water pressure falls below 0.05 MPa (0.5 bar), the
value flashes in the display.
If the water pressure falls below 0.03 MPa (0.3 bar), the
product switches off. The display shows 0.0 MPa (0.0 bar).
Fault F.22 is stored in the fault list.
▶
Top up the water in the heating installation to start up the
product again.
◁
The pressure value flashes in the display until a
pressure of 0.05 MPa (0.5 bar) or higher has been
reached.

Filling and purging the heating installation
Preliminary work
▶
Flush the heating installation through.

1.
Check the silicone hose connection (1) between the
pump's automatic air vent and the hydraulic console.
2.
Fill with water until the required filling pressure is
reached.
–
Recommended filling pressure: 1 ... 1.5 bar
◁
The heating and hot water functions cannot be activ-
ated.
◁
The pressure value flashes in the display until a
pressure of 0.05 MPa (0.5 bar) or higher has been
reached.
◁
An automatic air vent function is activated if the
pressure exceeds 0.05 MPa (0.5 bar) for longer than
15 seconds.
3.
Purge each radiator until the water escapes normally,
and then retighten the system's purging valves.
4.
Check that all connections are leak-tight.
Conditions: If the noise persists in the boiler
▶
Purge the product again by activating check programme
P.00.
