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.

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.
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.

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.
Information
Symbols
5778 747 GB

8
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).
Information
Intended use (cont.)
5778 747 GB

9
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 has been preset
Your heating system is preset at the factory and is
therefore ready for operation:
Central heating
■Between 06:00 and 22:00 h, the rooms are heated
to 20 °C "Set room temperature" (standard room
temperature).
■Between 22:00 and 06:00 h, the rooms are heated
to 3 °C "Reduced room temperature" (reduced
room temperature, frost protection).
DHW heating
■Between 05:30 and 22:00 h, the DHW is heated to
50 °C "Set DHW temperature". The DHW circula-
tion pump, if installed, is switched on.
■Between 22:00 and 05:30 h, the DHW cylinder is not
reheated. The DHW circulation pump, if installed, is
switched off.
Note
Any DHW heating begun before 22:00 h is termina-
ted.
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 (see page 24):
Do not overheat your home. Every degree of room
temperature reduction saves up to 6 % on your heat-
ing bills.
Do not set your standard room temperature ("Set
room temperature") higher than 20 °C.
■Time program (see page 14):
Heat your home to the standard room temperature
during the day and to the reduced temperature at
night. Set this via the time program.
■Operating program:
If you do not require central heating, select one of
the following operating programs:
–"Only DHW" (see page 29):
If you require no heating for your home in summer,
but you require DHW.
–"Standby mode" (see page 22):
If you do not need to heat your home and do not
require DHW for long periods.
■Short absence (see page 27):
Reduce the room temperature if you are going out
shopping, for example. For this, select "Economy
mode".
■Holidays (see page 24):
If you are going away, select the "Holiday pro-
gram":
The room temperature is reduced, and DHW heating
is turned off.
■Ventilation:
Close the thermostatic valves when venting. 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 (see page 30):
Only activate the DHW circulation pump for periods
in which DHW is regularly drawn off. Set this via the
time program.
■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 (see page 24):
You can select your individual preferred temperature
"Set room temperature" at any time in the standard
menu.

atures, for example different temperatures for day
and night time.
■Heating curve (see page 25):
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" (see page 26):
Select "Comfort mode" if you want to heat your
home to 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 (see pages 29 and 30):
Use the time program for DHW heating.
Use the time program for the DHW circulation pump.
During the selected time phases, DHW is available
at the draw-off points at the required temperature.

Energy situation of the heat generator
You can call up for the following information about the
energy situation and operating data of the heat gener-
ator:
■Current heating output
■Runtime (operating hours)
■Electricity consumption
■Gas consumption
Note
The energy cockpit provides the system user with
information about the thermal and electrical consump-
tion of the heating system throughout the year. These
values are calculated taking account of the system
components used and user behaviour (e.g. runtime
and utilisation level). Due to system-specific parame-
ters (e.g. elevation of the installation or flue system
design), there may be discrepancies between the dis-
played and actual consumption values.
To improve the accuracy of the display, we recommend
that the system user enters the calorific value, gas cor-
rection factor and gas meter readings. Seasonal envi-
ronmental conditions and other factors may neverthe-
less continue to cause discrepancies. Therefore, it has
to be noted that the displayed values are not deter-
mined using measuring equipment but are only calcu-
lated. The energy cockpit is intended to visualise con-
sumption to date and is useful for highlighting
increased or decreased consumption in specific com-
parison periods. It cannot be used as a reliable basis
for billing.
To enter additional data, see page 20.
Heating output, runtimes and consumption

The gas consumption for central heating is shown
in red.
The gas consumption for DHW heating is shown in
yellow.
8. Tap the diagram for a period (e.g. day). The gas
consumption for this period is displayed as a
numerical value.
Input of additional data for gas consumption
You can improve the accuracy of displayed gas con-
sumption values by entering your gas meter readings
as comparison values. Make the first input shortly after
commissioning or at the start of the heating season.
Make the second input at the end of the heating sea-
son so that at least 100 m3 of gas were consumed in
the past period. If required, this can be repeated for
the next heating season. The more comparison values
you enter, the more accurate the displayed gas con-
sumption values will be.
Note
■There is no retrospective correction of values that
have already been recorded.
■No additional consumer may be connected to the
gas meter.
01. Use to call up the energy cockpit from the stand-
ard menu.
02. Tap the heat generator.
03. Tap "Gas consumption".
04. Tap "Input, counter reading".
05. Confirm the message with "Yes".
06. Tap the entry field.
07. Enter the meter reading.
Use to remove existing values
08. Confirm twice with OK.
09. After a few months (ideally at the end of the heat-
ing season), enter the current meter reading as
the second value. For procedure, see above.
10. If you want to enter further values after some time:
Move the last entered value upwards. To do so,
tap "Move 2 to 1". To continue, see previous
steps.
Input of gas quality
Here you can enter values for the calorific value of the
gas used and its gas correction factor. Both values can
be found on your gas bill. If you do not have a gas bill,
you can request the information from your gas supply
utility.
