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.
Have installation or replacement work only 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).
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 06:00 and 22:00 h, the rooms are heated
to 20 °C "Set room temperature" (standard heating
mode).
■Between 22:00 and 06:00 h, the rooms are heated
to 3 °C "Set reduced room temp" (reduced room
temperature, frost protection).
DHW heating
■Between 05:30 and 22:00 h, the DHW is heated to
50 °C "Set DHW temperature". Any installed DHW
circulation pump is switched on.
■Between 22:00 and 05:30 h, the DHW cylinder is not
reheated. Any installed DHW circulation pump is
switched off.
Note
If DHW heating began before 22:00 h, it is stopped.
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 were set by your heating contrac-
tor.
Your heating contractor can make further settings for
you during commissioning.
You can change the settings at any time to suit your
individual requirements.
Power failure
All settings are saved if there is a power failure.
If the heating system has been shut down for a pro-
longed period, reset the date and time.
Tips on saving energy
Central heating
■Standard room temperature ("Set room tempera-
ture", see page 18):
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 (see page 18):
Heat your rooms 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:
–"Only DHW" (see page 23):
If you require no heating for your home in summer,
but you need hot water.
–"Standby mode" (see page 16):
If you don't need to heat your home and don't need
hot water for long periods.
■Short absence (see page 20):
Reduce the room temperature if you are going shop-
ping, for example. For this, select "Economy
mode".
■Holidays (see page 21):
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 to ventilate. Open the
windows fully for a brief time.
■Roller shutters:
Close roller shutters (where installed) at dusk.
■Thermostatic valves:
Ensure that thermostatic valves are properly set.
■Radiators:
Never cover radiators or thermostatic valves.
DHW heating
■DHW circulation pump (see page 24):
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 ("Set room tempera-
ture", see page 18):
You can select your individual preferred temperature
at any time in the standard menu.
■Preferred heating circuit (see page 26):
If your heating system consists of several heating cir-
cuits, you can make the most important adjustments
for a preferred heating circuit directly via the stand-
ard menu.
■Time program (see page 18):
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 (see page 19):
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.
■"Party mode" (see page 20):
If you want to heat rooms to a different temperature
from the one set in the time program, select "Party
mode".
Example: Late in the evening, the reduced room
temperature is set by the time program. Your guests
stay longer.
DHW heating
■Time program (see page 23 and 24):
Use the time program for DHW heating.
Use the time program for the DHW circulation pump.
During the selected time phases, DHW will be availa-
ble at the draw-off points at the required tempera-
ture.
