Target group
These operating instructions are
designed for heating system users.
This appliance can also be operated by
children of 8 years and older, as well as
by individuals with reduced physical,
sensory or mental faculties or those lack-
ing in experience and knowledge, provi-
ded such individuals are being super-
vised or have been instructed in the safe
use of this appliance as well as in any
risks arising from it.
!Please note
Supervise children in the proxim-
ity of the appliance.
■ Never permit children to play
with the appliance.
■ Cleaning and maintenance
must not be carried out by
unsupervised children.
Danger
Incorrectly executed work on the
heating system can lead to life
threatening accidents.
■ Work on gas installations must
only be carried out by a regis-
tered gas fitter.
■ Work on electrical equipment
must only be carried out by a
qualified electrician.
Danger
The appliance generates heat.
Hot surfaces can cause burns.
■ Never open the appliance.

flames and sparks. Do not
switch lights or electrical appli-
ances on or off.

If you smell flue gas
Danger
Flue gas can lead to life threat-
ening poisoning.
■ Shut down the heating system.
■ Ventilate the installation site.
■ Close all doors in the living
space.
In case of fire
Danger
If there is a fire, there is a risk of
burns and explosion.
■ Shut down the heating system.
■ Close shut-off valves in the fuel
supply lines.
■ Use a tested fire extinguisher,
class ABC.
What to do if the heating system
develops faults
Danger
Fault messages indicate faults in
the heating system. If faults are
not rectified, they can have life
threatening consequences.
Do not acknowledge fault mes-
sages several times in quick suc-
cession. Inform your heating con-
tractor so the cause can be ana-
lysed and the fault rectified.
Installation room conditions
Danger
Sealed vents result in a lack of
combustion air. This leads to
incomplete combustion and the
formation of life threatening car-
bon monoxide.
Never cover or close existing
vents.
Do not make any subsequent
modifications to the building
characteristics that could affect
safe operation (e.g. cable/pipe-
work routing, cladding or parti-
tions).
Danger
Easily flammable liquids and
materials (e.g. naphtha, solvents,
cleaning agents, paints or paper)
can cause deflagration and fire.
Never store or use such materials
in the installation room or in direct
proximity to the heating system.
!Please note
Incorrect ambient conditions can
lead to heating system damage
and can put safe operation at
risk.
■ Ensure ambient temperatures
are above 0 °C and below
35 °C.
■ Prevent air contamination by
halogenated hydrocarbons
(e.g. as contained in paints,
solvents or cleaning fluids) and
excessive dust (e.g. through
grinding/polishing work).
■ Avoid continuously high humid-
ity levels (e.g. through continu-
ous drying of washing).

Extractors
Operating appliances that extract air to
the outside (cooker hoods, extractors, air
conditioning units, etc.) can create neg-
ative pressure. If the boiler is operated at
the same time, this can lead to reverse
flow of the flue gas.
Danger
The simultaneous operation of
the boiler and appliances that
extract air to the outside can
result in life threatening poison-
ing due to reverse flow of the flue
gas.
Take suitable steps to ensure an
adequate supply of combustion
air. If necessary, contact your
heating contractor.
Auxiliary components, spare and
wearing parts
!Please note
Components not tested with the
heating system may damage it or
affect its functions.
Have installation or replacement
work only carried out by qualified
contractors.

The commissioning and adjusting of the
control unit to local conditions and to
building characteristics, plus the instruc-
tion of the user in operating the system,
must be carried out by your heating con-
tractor.
As the user of new combustion equip-
ment, you may be obliged to notify your
local flue gas inspector of the installation
[check local regulations]. Your local flue
gas inspector (where applicable) will
also provide you with information on
additional activities concerning your
combustion equipment (such as regular
testing, cleaning, etc.).

Terminology
To provide you with a better understand-
ing of the functions of your Viessmann
control unit some terminology is
explained.
The terms are marked as follows:
Further information can be found
in chapter "Terminology" in the Ap-
pendix.
Your system is preset at the factory
Your heating system is preset at the fac-
tory and is therefore ready for opera-
tion.
Your heating contractor can make fur-
ther adjustments for you during commis-
sioning.
You can change these settings at any
time to suit your individual require-
ments.

Energy saving tips
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:
– If you do not wish to heat rooms in
summer but require domestic hot
water, set rotary selector "tw" (see
page 15) and turn rotary selector
"tr" to "0".
– If you require neither central heating
nor DHW for a prolonged period, set
rotary selectors "tr" and "tw" to
"0".
■Ventilation:
To ventilate, open windows fully
briefly, and meanwhile close the ther-
mostatic valves (if there is no mechan-
ical ventilation system installed).
■Roller shutters:
Close roller shutters (where installed)
at dusk.
■Thermostatic valves:
Ensure that thermostatic valves are
properly set.
■Radiators:
Never cover radiators or thermostatic
valves.
DHW heating
■DHW temperature:
Never set the DHW cylinder tempera-
ture excessively high (see page 15).
■Hot water consumption:
Consider showering instead of running
a bath. A shower generally uses less
energy than a full bath.

DHW heating
■Comfort function:
If the comfort function is switched on,
the instantaneous water heater is kept
up to temperature (standby). Hot water
is therefore quickly available. Start
comfort function, see page 16.
