Note

Ask the competent person to
explain where the isolators are
located and how they are oper-

7.1.1 Preventing frost damage
The product is equipped with a frost pro-
tection function.
If the heating flow temperature falls be-
low 5 °C when the main switch is switched
on, the product starts up and heats the cir-
culating water on both the heating side
and the hot-water side (if available) to ap-
prox. 30 °C.
Caution.
Risk of material damage due
to frost.
The frost protection function
cannot guarantee flow through
the entire heating installation,
which means that parts of the
heating installation may freeze
and therefore become dam-
aged.
▶
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.
▶
Consult a competent person about this.
7.1.2 Draining the heating
installation
Another way to protect the heating install-
ation and the product from frost for very
long switch-off times is to drain them com-
pletely.

Consult a competent person about this.
