In case of water leaking from the appliance
Danger
Water leaking from the appliance poses an elec-
trocution hazard.
■Switch off the heating system at the external
isolation point (e.g. fuse box, domestic power
distribution unit).
■Notify your local heating contractor.
What to do if the heating system develops a fault
Danger
Fault messages point to faults in the heating
system. If faults are not rectified, they can have
life threatening consequences.
Never acknowledge fault messages several
times in quick succession. Inform your heating
contractor so the cause can be analysed and
the fault rectified.
Installation room requirements
Danger
Sealed vents result in a lack of combustion air.
This leads to incomplete combustion and the
formation of life threatening carbon monoxide.
Never cover or close existing vents.
Never make any subsequent modifications to
the building characteristics that could affect safe
operation (e.g. cable/pipework routing, cladding
or partitions).
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 installa-
tion 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, sol-
vents or cleaning fluids) and excessive dust
(e.g. through grinding/polishing work).
■Avoid continuously high humidity levels (e.g.
through continuous drying of washing).
Extractors
The operation of appliances that extract air to the out-
side (cooker hoods, extractors, air conditioning units,
etc.) can create negative pressure. If the boiler is oper-
ated at the same time, this can lead to a 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 poisoning due to
reverse flow of the flue gas.
Take suitable steps to ensure an adequate sup-
ply 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 the system or affect its function.
Have all installation or replacement work carried
out exclusively by qualified contractors.

comply with EN 12828, with due attention paid to the
associated installation, service and operating instruc-
tions. It is only designed for heating up heating water
that is of potable water quality.
Intended use 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 shall be deemed
inappropriate.
Any usage beyond this must be approved by the man-
ufacturer in each individual case.
Incorrect usage or operation of the appliance (e.g. the
appliance being opened by the system user) is prohibi-
ted and will result in an exclusion of liability. Incorrect
usage also occurs if the components in the heating

7
The commissioning and adjusting 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.
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 [where applicable] will also provide you with
information on additional activities concerning your
combustion equipment (such as regular testing, clean-
ing, etc.).
Your system is preset at the factory
Your heating system is preset at the factory and is
therefore ready for operation.
Your heating contractor can make further adjustments
for you during commissioning.
You can change these settings at any time to suit your
individual requirements.
Power failure
All settings are saved if there is a power failure.
Energy saving tips
Central heating
■Room temperature:
Never overheat your rooms. Every degree of room
temperature reduction saves up to 6 % on your heat-
ing bills.
Never set your room temperature 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 (see page 11).
–If you require neither room heating nor DHW for an
extended period, set the boiler water temperature
and the DHW temperature to OFF.
■Ventilation:
To ventilate, open windows fully briefly, and mean-
while close the thermostatic valves (if there is no
mechanical ventilation system installed).
■Roller shutters:
Close roller shutters (where installed) at dusk.
■Thermostatic valves:
Ensure that thermostatic valves are properly adjus-
ted.
■Radiators:
Never cover radiators or thermostatic valves.
DHW heating
■DHW temperature:
Never set the DHW cylinder temperature excessively
high (see page 14).
■Hot water consumption:
Consider showering instead of running a bath. A
shower generally uses less energy than a full bath.

All appliances may be cleaned with a commercially
available domestic cleaning agent (non-scouring).
Inspection and maintenance
The inspection and maintenance of a heating system
is prescribed by the Energy Saving Ordinance [EnEV -
Germany] and the DIN 4755, DIN 1988-8 and EN 806
standards.
Regular maintenance ensures trouble-free, energy effi-
cient and environmentally responsible heating opera-
tion. For this, we strongly advise you to arrange an
inspection and maintenance contract with your heating
contractor.
Boiler
Increasing boiler contamination raises the flue gas
temperature and thereby increases energy losses. All
boilers should therefore be cleaned annually.
Logbook
Please ensure that you have a Logbook supplied with
your appliance. This Logbook should be completed by
your installer to verify that the correct installation and
commissioning procedure was followed.
Failure to complete the Logbook may result in difficul-
ties should a problem arise with your appliance during
the guarantee period. This Logbook forms part of the
industry's Benchmark code of practice for the installa-
tion, commissioning and servicing of central heating
systems.
All Gas Safe Registered Installers carry a ID card and
have a registration number. Both should be recorded in
your Logbook. You can check your installer is Gas
Safe registered by calling GasSafe register on +44
(0)800 408 5500 or visit the website www.gassafer-
egister.co.uk

Constant temperature operation
In constant temperature operation, the heating water is
constantly (continuously) heated to the selected boiler
water temperature.
Heating water temperature
The temperature of the heating water that flows to the
radiators (roughly equal to boiler water temperature).
Boiler water temperature
The heating water in the boiler (boiler water) is heated
to the temperature set at the control unit. This temper-
ature is referred to as boiler water temperature.
Open flue operation
The combustion air is drawn from the room where the
boiler is installed.
Room sealed operation
The combustion air is drawn from outside the building.
Room temperature-dependent operation
A room temperature controller captures the room tem-
perature and compares this with the required room
temperature you set. If the room temperature is lower
than the required value, the boiler is switched on; if the
room temperature is higher than the required value,
the boiler is switched off.
Make any settings on the connected room temperature
controller using the relevant operating instructions.
Note
The heating water temperature must be set high
enough in order to achieve the required room tempera-
ture.
Safety valve
Safety equipment that must be installed in the cold
water pipe by your heating contractor. The safety valve
opens automatically to prevent excess pressure in the
DHW cylinder.
Drinking water filter
A device that removes solids from potable water. The
drinking water filter is installed in the cold water pipe
upstream of the DHW cylinder or the instantaneous
water heater.
Flow temperature
The temperature of the heating water that flows to the
radiators (in the flow line). Accordingly, the tempera-
ture of the heating water that flows from the radiators
to the boiler (in the return line) is referred to as return
temperature.
Weather-compensated operation
In weather-compensated mode, the flow temperature
is controlled according to the outside temperature. This
means that no unnecessary heat is generated in order
to heat the rooms to the required room temperature
you selected.
The outside temperature is captured and transmitted to
the control unit by a sensor fitted outside the building.
Information on disposal
Disposal of packaging
You heating contractor will dispose of the packaging of
your Viessmann product.
DE: Packaging waste is channelled for recycling to a
certified disposal contractor in line with statutory
regulations.
AT: Packaging waste is channelled for recycling to a
certified disposal contractor in line with statutory
regulations. Use the ARA statutory disposal sys-
tem (Altstoff Recycling Austria AG, licence num-
ber 5766).
Final decommissioning and disposal of the heating system
Viessmann products can be recycled. Components
and fluids from your heating systems are not part of
ordinary domestic waste.
Please contact your heating contractor in connection
with the correct disposal of your old system.
