Checking the filling and supplementary water
▶
Before filling the installation, measure the hardness of the
filling and supplementary water.
Treating the filling and supplementary water
▶
Observe all applicable national regulations and technical
standards when treating the filling and supplementary
water.
Applicability: Germany
▶
In particular, observe VDI directive 2035, sheets 1 and 2.
Provided the national regulations and technical standards
do not stipulate more stringent requirements, the following
applies:
You must treat the heating water in the following cases:
–
If the entire filling and supplementary water quantity dur-
ing the operating life of the system exceeds three times
the nominal volume of the heating installation, or
–
If the guideline values listed in the following table are not
met, or
–
If the pH value of the heating water is less than 8.2 or
more than 10.0.

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.

Reading off the filling pressure
The unit comes with a bar chart showing the pressure and a
digital pressure display.
▶
To read off the digital filling pressure value, press the
button twice.
For the heating installation to operate properly, the bar chart
in the display must remain roughly in the centre (between the
dotted limit values). This corresponds to a filling pressure of
between 100 kPa and 150 kPa (1.0 bar 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.
7.12
Preventing low water pressure
To prevent damage to the heating installation that is caused
by low filling pressure, the product is fitted with a water pres-
sure sensor. If the water pressure falls below 80 kPa (0.8
bar), the unit indicates low pressure by displaying a flashing
pressure value. If the filling pressure falls below a value of 50
kPa (0.5 bar), the unit switches off. The display shows F.22.
▶
Top up the heating water to start the product up again.
A flashing pressure value is shown in the display until a pres-
sure of 110 kPa (1.1 bar) or higher has been reached.
▶
If you notice frequent drops in pressure, determine and
eliminate the cause.
