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.

Intended use
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 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
system are modified from their intended use (e.g. if the
flue gas and ventilation air paths are sealed).

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.

page 12.
Operation with room temperature controller
Further information can be found in chapter
"Terminology" in the appendix.
Make any settings on the connected room temperature
controller using the relevant operating instructions.
Note
Set the boiler water temperature high enough to ach-
ieve the required room temperature.
For boiler water temperature setting, see page 12
Weather-compensated operation
Further information can be found in chapter
"Terminology" in the appendix.
In weather-compensated mode, the boiler water tem-
perature is regulated subject to the outside tempera-
ture.
Note
Connect a room temperature controller to your heating
system to prevent heat being generated unnecessarily
at times when you do not require central heating. This
enables central heating to be suspended at night, for
example, in order to save energy.
For setting the room temperature, see page 13.
