Safety instructions explained
Danger
This symbol warns against the risk of injury.
!Please note
This symbol warns against the risk of material
losses and environmental pollution.
Note
Details identified by the word "Note" contain additional
information.
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 lacking
in experience and knowledge, provided such individu-
als are being supervised or have been instructed in the
safe use of this appliance as well as in any risks aris-
ing from it.
!Please note
Supervise children in the proximity of the appli-
ance.
■Never permit children to play with the appli-
ance.
■Cleaning and maintenance must not be car-
ried 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 registered 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.
■Never touch the hot surfaces of uninsulated
pipes, fittings or flue pipes.
If you smell gas
Danger
Escaping gas can lead to explosions which may
result in serious injury.
■Do not smoke. Prevent naked flames and
sparks. Do not switch lights or electrical appli-
ances on or off.
■Close the gas shut-off valve.
■Open windows and doors.
■Evacuate any people from the danger zone.
■Notify your gas or electricity supplier and your
local heating contractor from outside the build-
ing.
■Shut off the electricity supply to the building
from a safe place (outside the building).
If you smell flue gas
Danger
Flue gas can lead to life threatening 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 messages several
times in quick succession. Inform your heating
contractor so the cause can be analysed 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 carbon 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/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
Operating appliances that extract air to the outside
(cooker hoods, extractors, air conditioning units, etc.)
can create negative 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 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 it or affect its functions.
Only have installation or replacement work car-
ried out by qualified contractors.

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.
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).
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.
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).
Your system is preset at the factory
The control unit is preset at the factory to " " for
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").
DHW heating
■The DHW is heated up to 50 °C.
■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 "DHW heat-
ing").
Frost protection
■Your boiler and DHW cylinder are protected against
frost.
Power failure
■All data is saved if there is a power failure.
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).

Use the adjustment options on the control unit and the
room temperature control unit:
■Do not overheat your rooms; you can save up to 6 %
on your heating costs for every degree you reduce
your room temperature.
Set your room temperature no higher than 20 °C
(see page 11).
■Do not set your DHW temperature too high (see
page 12).
■Select the operating program that meets your current
requirements:
–In the summer, when you don't want to heat any
rooms but do need DHW, select operating program
" " (see page 12).
–If you do not want to heat any rooms and require
no hot water for a prolonged period of time, select
operating program " " (see page 9).
Further recommendations:
■Correct ventilation/airing.
Fully open windows for a short time and close the
thermostatic valves while airing.
■Close roller shutters (if installed) at dusk.
■Set thermostatic valves correctly.
■Never cover radiators or thermostatic valves.
■Controlled DHW consumption: A shower generally
uses less energy than a full bath.

1. Check the heating system pressure at the
pressure gauge. The system pressure is too low if
the indicator points to the area below 1.0 bar. In this
case, top up with water or notify your local heating
contractor.
2. For open flue operation:
Check that the ventilation apertures of the installa-
tion room are open and unrestricted.
Note
With open flue operation, the combustion air is
drawn from the installation room.
3. Open the gas shut-off valve.
Note
Ask your heating contractor to explain the position-
ing and handling of these components.
4. Switch ON the power supply, e.g. at a separate
MCB/fuse or a mains isolator.
5. Turn ON/OFF switch " " on.
After a short while, the standard display appears
and the green ON indicator illuminates. Your heat-
ing system and room temperature control unit are
now ready for operation.
