What to do if water escapes from the appliance
Danger
When water escapes from the appliance there is
a risk of electrocution.
■Switch off the heating system by means of an
external isolator (for example fuse box,
domestic power distribution).
■Notify your heating contractor.
What to do if the heating system develops a fault
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 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.
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
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 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 that have not been 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 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 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 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 (where applicable) will also provide you with
information on additional activities concerning your
combustion equipment (such as regular testing, clean-
ing, etc.).
Terminology
To provide you with a better understanding of the func-
tions of your Vitotronic control unit, some terminology
is explained.
The terms are marked as follows:
Further information can be found in chapter
"Terminology" in the Appendix.
Your system has been preset
Your heating system is preset at the factory and is
therefore ready for operation:
Central heating
■Between 00:00 and 24:00 h, the rooms are heated
to 20 °C "Room temp target" (standard room tem-
perature).
DHW heating
■Between 00:00 and 24:00 h DHW will be heated to
50 °C "DHW temperature setpoint". Any installed
DHW circulation pump is switched on.
Frost protection
■Your boiler and DHW cylinder are protected against
frost.
Wintertime/summertime changeover
■This changeover is automatic.
Date and time
■The date and time have been set by your heating
contractor.
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
■Standard room temperature ("Room temp tar-
get"):
Never overheat your home. Every degree of room
temperature reduction saves up to 6 % on your heat-
ing bills.
Never set your standard room temperature higher
than 20 °C.
■Time program:
Heat your home to the standard room temperature
during the day and the reduced temperature at night.
Set the time program for this.
■Operating program:
If you do not require central heating, select one of
the following operating programs:
–"DHW only":
If you require no heating for your home in summer,
but you need hot water.
–"Standby mode":
If you don't need to heat your home and don't need
hot water for long periods.
■Short absence:
Reduce the room temperature if you are going out
shopping, for example. For this, select "Economy
mode".
Introductory information
Commissioning
5546 499 CA

9
■Holiday:
If you are going away, select the "Holiday pro-
gram":
The room temperature will be reduced, and DHW
heating will be turned off.
■Ventilation:
Close the thermostatic valves when ventilating. Open
the windows fully for a brief time.
■Roller shutters:
Close roller shutters (if installed) at dusk.
■Thermostatic valves:
Ensure that thermostatic valves are properly adjus-
ted.
■Radiators:
Never cover radiators or thermostatic valves.
DHW heating
■DHW circulation pump:
Only activate the DHW circulation pump for periods
in which DHW is regularly drawn off. Set the time
program for this.
■DHW consumption:
Consider showering instead of running a bath. A
shower generally uses less energy than a full bath.
For additional energy saving functions of the Vitotronic
control unit, please contact your heating contractor.
Tips for greater comfort
Central heating
■Standard room temperature ("Room temp tar-
get"):
You can select your individual preferred temperature
at any time in the standard menu.
■Time program:
Make use of the time program. In the time program,
you can set time phases with different room temper-
atures, for example different temperatures for day
and night time.
■Heating curve:
The heating curve enables you to individually adjust
the heating system to the actual heat demand in your
home. If set correctly, your preferred temperature will
be achieved all year round.
■"Comfort mode":
Select "Comfort mode" if you want to heat your
interior at a temperature that deviates from that in a
time program.
Example: Late in the evening, the reduced room
temperature is set by the time program. Your guests
stay longer.
DHW heating
■Time program:
Make use of the time program.

pressure gauge. If the pressure of the heating sys-
tem is too low, top up the water or notify your heat-
ing contractor.
2. Open the gas shut-off valve on every boiler.
3. Switch ON the power supply, e.g. at a separate
MCB/fuse or a mains isolator.
4. Switch ON the ON/OFF switch on every control
unit.
After a short time, the standard menu (see page 10)
or the default display (see page 14 and 15)

The time program allows you to divide the day into
sections. These are called time phases. It is for you to
decide what happens in these time phases, e.g.
whether your rooms should be heated to the standard
room temperature.
■You can set the time program individually, to be the
same, or different, for every day of the week.
■You can select up to 4 time phases per day.
■For each time phase, you select the start and end
points.
■In the main menu, you can scan the time programs
under "Information" (see from page 49).
Note
The settings described in the following central heating
example for Heating circuit 1 apply equally to DHW
heating and the DHW circulation pump.
