Warning of material losses and
environmental pollution
Intended use
Terminology
The appliance is intended solely for installation and
operation in sealed unvented heating systems that
comply with EN 12828, with due attention paid to
the associated installation, service and operating
instructions. It is only designed for heating up
heating water that is of potable water quality.
Intended use presupposes that a xed installation
in conjunction with permissible, system-specic
components has been carried out.
To provide you with a better understanding of the
functions of your Viessmann control unit, some
terminology is explained.
The terms are marked as follows:
Commercial or industrial usage for a purpose other
than heating the building or DHW shall be deemed
inappropriate.
Any usage beyond this must be approved by the
manufacturer in each individual case.
Incorrect usage or operation of the appliance
(e.g. the appliance being opened by the system user)
is prohibited and will result in an exclusion of liability.
Incorrect usage also occurs if the components in the
heating system are modied from their intended
function.
Further information can be found in chapter
Terminology in the Appendix.

Commissioning
Your system is preset at the factory
Energy saving tips
The commissioning and matching of the control unit to
local conditions and to building characteristics, plus the
instruction of the user in operating the system, must be
carried out by your heating contractor.
Your heating system is preset at the factory and is
therefore ready for operation.
Your heating contractor can make further settings for
you during commissioning.
You can change the settings at any time to suit your
individual requirements.
Central heating
■
Room temperature:
Never overheat your rooms. Every degree of room
temperature reduction saves up to 6 % on your
heating bills.
Set your room temperature no higher than 20 °C.
■
Operating modes:
If you do not require central heating, select one of
the following operating modes:
– In summer, if you do not want to heat any rooms
but do need DHW, set the boiler water
temperature to OFF.
– If you do not require central heating or DHW for a
long period of time, set the boiler water and DHW
temperature to OFF.
■
Roller shutters:
Close roller shutters (where installed) at dusk.
Power failure
All settings are retained if there is a power failure.
Introductory information
■
Thermostatic valves:
Ensure that thermostatic valves are properly
adjusted.
■
Radiators:
Never cover radiators or thermostatic valves.
DHW heating
■
DHW temperature:
Never set the DHW cylinder temperature
excessively high (see page 15).
■
DHW consumption:
Consider showering instead of running a bath. A
shower generally uses less energy than a full bath.
