The structural conditions that may affect
the operational safety of the product.
1.2.10 Risk of injury and material damage
due to incorrect maintenance or
repairs
As a result of unauthorised interference or
tampering with the product or parts of the
system, the operational safety of the product
can no longer be ensured and the guarantee
therefore becomes void.
▶
Never interfere or tamper with the product
or other parts of the system.
▶
Never try to carry out maintenance work or
repairs on the product yourself.
▶
Do not damage or remove any seals on
components. Only qualified competent
persons and factory service personnel are
authorised to make modifications to sealed
components.
▶
Have inspection and maintenance work
carried out by a competent person.
1.2.11 Frost damage due to an unsuitable
installation site
Frost poses a risk of damage to the product
and the whole heating installation.
▶
You should therefore ensure that the heat-
ing installation always remains in opera-
tion during freezing conditions and that all
rooms are sufficiently heated.
Even if rooms, or the whole dwelling, are not
in use for certain periods, the heating must
remain in operation.
Frost protection and monitoring devices are
only active while the product is connected
to the power supply. The product must be
connected to the power supply.
1.2.12 Frost damage caused by insufficient
room temperature
If the room temperature is set too low in indi-
vidual rooms, it cannot be ruled out that sec-
tions of the heating installation might be dam-
aged by frost.
