The appliance is only intended to be
installed and operated in sealed unven-
ted heating systems that comply with
EN 12828, with due attention paid to the
associated installation, service and
operating instructions.
Depending on the version, the appliance
can only be used for the following pur-
poses:
■ Central heating
■ Central cooling
■ DHW heating
The range of functions can be extended
with additional components and acces-
sories.
Intended use presupposes that a fixed
installation in conjunction with permissi-
ble, system-specific components has
been carried out.
Commercial or industrial usage for a pur-
pose other than central heating/cooling
or DHW heating shall be deemed inap-
propriate.
Any usage beyond this must be
approved by the manufacturer for the
individual case.
Incorrect usage or operation of the appli-
ance (e.g. the appliance being opened
by the system user) is prohibited and
results in an exclusion of liability. Incor-
rect usage also occurs if the components
in the heating system are modified from
their intended function.
Note
The appliance is intended exclusively for
domestic use, i.e. even users who have
not had any instruction are able to oper-
ate the appliance safely.
