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).
