Decommissioning
8.1
Temporarily decommissioning the product
Caution.
Risk of material damage due to frost
The frost protection and monitoring devices
are only active while the unit is connected
to the power grid, the product is switched on
via the main switch and the gas stopcock is
open.
▶
You must use the control if you want to
activate and deactivate the product in
normal mode.
▶
If no control is present when a main switch
has been switched on, set the rotary
knobs for the target heating flow and
cylinder values to the anti-clockwise end
stop.
▶
Do not disconnect the product from the
power grid when it is in normal mode.
▶
Leave the main switch in position 1 in
normal mode.

The isolators are not included in the scope of deliv-
ery for your product. They are installed on-site by
the competent person. Ask the competent person
to explain where the isolators are located and how
they are operated.
8.1.1
Preventing frost damage
The product is equipped with a frost protection function.
If the heating flow temperature falls below 8 °C when the
main switch is switched on, the product's pump starts up.
If the heating flow temperature falls below 5 °C when the
main switch is switched on, the product starts up and heats
the circulating water on both the heating side and the hot-
water side (if available) to approx. 30 °C.
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.
▶
Consult a competent person about this.
8.1.2
Draining the heating installation
Another way to protect the heating installation and the
product from frost for very long switch-off periods is to drain
them completely.
▶
Consult a competent person about this.
