Intended Use; Commissioning; Your System Is Preset At The Factory; Terminology - Viessmann VITODENS Operating Instructions Manual

Intended use

The appliance is only intended to be installed and
operated in sealed unvented heating systems that
comply with EN 12828, with due attention paid to the
associated installation, service and operating instruc-
tions. It is only designed for the heating of water that is
of potable water quality.
Intended usage presupposes that a fixed installation in
conjunction with permissible, system-specific compo-
nents has been carried out.
Commercial or industrial usage for a purpose other
than heating the building or DHW does not comply with
regulations.

Commissioning

The commissioning and matching of the control unit to
local conditions and building characteristics, as well as
instructing the user in the operation of the system,
must be carried out by your heating contractor.

Your system is preset at the factory

The control unit is preset at the factory to "
central heating and DHW heating.
Your heating system is therefore ready for operation:
Central heating
The rooms are heated in accordance with the set-
■
tings on your control unit and room temperature con-
trol unit.
Your heating contractor can make further settings for
■
you during commissioning.
You can change any settings individually at any time
to suit your requirements (see chapter "Central heat-
ing").

Terminology

To provide you with a better understanding of the func-
tions of your control unit, the appendix contains the
chapter "Terminology" (see page 23).
Any usage beyond this must be approved by the man-
ufacturer for the individual case.
Incorrect usage or operation of the appliance (e.g. the
appliance being opened by the system user) is prohibi-
ted and results in an exclusion of liability. Incorrect
usage also occurs if the components in the heating
system are modified from their intended function (e.g.
if the flue gas and ventilation air paths are sealed).
As the user of new combustion equipment, you may be
obliged to notify your local flue gas inspector of the
installation [check local regulations]. Your local flue gas
inspector will also inform you [where appropriate]
about work he may be required to carry out on your
combustion equipment (e.g. regular checks, cleaning).
" for DHW heating
The DHW is heated up to 50 °C.
