Caution.
Risk of material damage if the heating
water is treated with unsuitable additives.
Unsuitable additives may cause changes in
the components, noises in heating mode and
possibly subsequent damage.
▶
Do not use any unsuitable frost and cor-
rosion protection agents, biocides or seal-
ants.
No incompatibility with our products has been detected to
date with proper use of the following additives.
▶
When using additives, follow the manufacturer's instruc-
tions without exception.
We accept no liability for the compatibility of any additive or
its effectiveness in the rest of the heating system.

7.7
Preventing low water pressure
To ensure that the heating installation operates smoothly,
the indicator on the pressure gauge must point to the upper
half of the grey area or to the middle of the bar graph display
in the display (marked by the dashed limit values) when the
heating installation is cold. This corresponds to a filling pres-
sure of between 0.1 MPa and 0.2 MPa (1.0 bar and 2.0 bar).
If the heating installation extends over several storeys,
higher filling pressures may be required to avoid air entering
the heating installation.
If the filling pressure falls below 0.08 MPa (0.8 bar), the
product indicates low pressure by displaying a flashing
pressure value. If the filling pressure falls below 0.05 MPa
(0.5 bar), the product switches off. The display shows
F.22
.
▶
Top up the heating water to start the product up again.
The pressure value flashes in the display until a pressure of
0.11 MPa (1.1 bar) or higher has been reached.

Filling the heating installation
1
1.
Flush the heating installation through.
2.
Select the check programme
P.06
.
◁
The diverter valve moves to the mid-position, the
pumps do not run and the product does not switch
to heating mode.
Note
The cap on the automatic air vent
(1)
has
already been opened at the factory.
3.
Connect the filling and drainage tap in the heating in-
stallation to a heating water supply, if possible with the
cold water valve, in accordance with the relevant stand-
ards.
4.
Open the heating water supply.
5.
Open all thermostatic radiator valves.
6.
If necessary, check that both service valves on the
product are open.
7.
Slowly open the filling and drainage tap so that the wa-
ter flows into the heating system.
8.
Purge the lowest radiator until water flows out of the
purging valve without bubbles.
9.
Purge all other radiators until the entire heating system
has been filled with water.
10. Close all purging valves.
11. Monitor the rising filling pressure in the heating installa-
tion.
12. Fill with water until the required filling pressure is
reached.
13. Close the filling and drainage tap and the cold water
valve.
14. Check all connections and the entire system for leaks.
