Extractors
Operating appliances that extract air to
the outside (cooker hoods, extractors, air
conditioning units, etc.) can create neg-
ative 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 poison-
ing due to reverse flow of the flue
gas.
Take suitable steps to ensure an
adequate supply 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 carried out by qualified
contractors.

The appliance is only intended to be
installed and operated in sealed unven-
ted heating systems that comply with
EN 12828, with due attention paid to the
associated installation, service and
operating instructions. 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 permissi-
ble, system-specific components has
been carried out.
Commercial or industrial usage for a pur-
pose other than heating the building or
DHW does not comply with regulations.
Any usage beyond this must be
approved by the manufacturer for the
individual case.
Incorrect usage or operation of the appli-
ance (e.g. the appliance being opened
by the system user) is prohibited and
results in an exclusion of liability. Incor-
rect 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 build-
ing characteristics, as well as instructing
the user in the operation of the system,
must be carried out by your heating con-
tractor.
As the user of new combustion equip-
ment, 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, clean-
ing).
Terminology
To provide you with a better understand-
ing of the functions of your Vitotronic
control unit, some terminology is
explained.
The terms are marked as follows:
Introductory information

5592 682 GB

9
Further information can be found
in chapter "Terminology" in the Ap-
pendix.
Your system has been preset
Your heating system is preset at the fac-
tory and is therefore ready for opera-
tion:
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 temper-
ature". 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 pro-
tected against frost.
Wintertime/summertime changeover
■ This changeover is automatic.
Date and time
■ The date and time were set by your
heating contractor.
Your heating contractor can make fur-
ther settings for you during commission-
ing.
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 prolonged period, reset the
date and time.

Central heating
■Standard room temperature ("Set
room temperature", see page 25):
Never overheat your home. Every
degree of room temperature reduction
saves up to 6 % on your heating bills.
Never set your standard room temper-
ature higher than 20 °C.
■Time program (see page 26):
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 31):
If you require no heating for your
home in summer, but you need hot
water.
–"Standby mode" (see page 23):
If you don't need to heat your home
and don't need hot water for long
periods.
■Short absence (see page 29):
Reduce the room temperature if you
are going shopping, for example. For
this, select "Economy mode".
■Holidays (see page 30):
If you are going away, select the "Hol-
iday program":
The room temperature will be reduced,
and DHW heating will be turned off.
■Ventilation:
Close the thermostatic valves to ven-
tilate. 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 32):
Only activate the DHW circulation
pump for periods in which DHW is reg-
ularly 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.
