4.14.2 Filling the heating installation
Caution.
Risk of material damage due to heating
water that is extremely calciferous or cor-
rosive or contaminated by chemicals.
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 installation with suit-
able heating water.
▶
In case of doubt, ask a competent person
for details.
1.
Ask a competent person where the filling cock is loc-
ated.
2.
Connect the filling cock to a hot water supply in the way
you were told by the competent person.
3.
Open all radiator valves (thermostatic radiator valves) of
the heating installation.
4.
Open the hot water supply.
5.
Turn the filling cock on slowly and allow water to flow in
until the required filling pressure has been reached.
6.
Close the hot water supply.
7.
Purge all radiators.
8.
Check the filling pressure in the display.
9.
Top up with more water if necessary.

Protecting the heating installation against
frost
4.15.1 Frost protection function
Caution.
Risk of material damage due to frost.
The frost protection function cannot guaran-
tee flow through the entire heating installa-
tion, which means that parts of the heating
installation may freeze and therefore become
damaged.
▶
During a period of frost, ensure that the
heating installation remains in operation
and that all rooms are sufficiently heated,
even when you are away.
Note
To keep the frost protection devices active, you
should switch your product on and off using the
controller, if one is provided.
If the heating flow temperature falls below 5 °C when the
on/off button is on, the product comes into operation and
heats the circulating water to approx. 30 °C on both the heat-
ing side and the hot water side (if available).
4.15.2 Draining the heating installation
When the unit is switched off for an extended period, frost
protection can be guaranteed by completely draining the
heating installation and the product.
▶
Consult a competent person about this.
