3.4 Protecting the heating

installation against frost

3.4.1 Frost protection function

Caution.

Risk of material damage due

to frost.

The frost protection function

cannot guarantee circulation

through the entire heating in-

stallation. Under certain circum-

stances, there is therefore a risk

of frost to certain parts of the

heating installation, which may

cause damage.

▶During a period of frost, en-

sure that the heating installa-

tion remains in operation and

that all rooms are sufficiently

heated, even when you are

away.

Note

To ensure that the frost protection

devices remain ready for operation,

the boiler must be switched on.

If the heating flow temperature falls below

5 °C when the on/off button is switched

on, the product starts up and heats the

circulating water on the heating side to

approx. 30 °C.
