If you smell gas
Danger
Escaping gas can lead to explosions which may
result in serious injury.
■Never smoke. Prevent naked flames and
sparks. Never 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 and power supply utility and
your local heating contractor from outside the
building.
■Have the power supply to the building shut off
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
Fire presents a risk of burns and explosion.
■Shut down the heating system.
■Close the shut-off valves in the fuel supply
lines.
■Use a tested fire extinguisher, class ABC.
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.

Terminology
To provide you with a better understanding of the func-
tions of your Vitotronic control unit, some terminology
is explained. This information can be found in chapter
"Terminology" in the Appendix.
Intended use
The device is intended to control only Viessmann
medium sized and industrial/commercial boilers with oil
or gas burners, in line with the intended use of those
appliances. Observe the relevant installation, service
and operating instructions.
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 function.

The Vitotronic 100, type CC1E and type CC1I control
units are designed for the control of single boiler sys-
tems with a constant boiler water temperature.
The Vitotronic control unit is factory-configured as a
"Single boiler constant control".
During operation with a constant boiler water tempera-
ture, the boiler provides heating water at a constant
temperature, independent of the outside temperature.
In single boiler systems, central heating and DHW
heating are provided at a constant boiler water temper-
ature. The flow temperature for the DHW cylinder cor-
responds to the set boiler water temperature. In con-
junction with separately connected control units, the
flow temperature for central heating can be regulated
to lower temperatures.
Note
Alternatively, your heating contractor can configure the
Vitotronic control unit as a "Boiler in the Cascade":
The Vitotronic control unit is therefore suitable for con-
trol of the boiler water temperature of a boiler in a multi
boiler system.
You can find all information on operation in the
"Vitotronic 300" operating instructions.
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
Your heating system is preset at the factory and 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-
troller.
DHW heating
■DHW is heated to 50 °C.
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.
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.

Information on the energy consumption figures
shown
The calculation of the energy consumption takes into
account the installed system components and the user
behaviour (e.g. operating time and utilisation level).
Depending on system-specific conditions, differences
may arise between the displayed (calculated) and
actual consumption figures.
They therefore cannot be used as a binding basis for
billing with the power supply utility.

Special operating programs
The following special operating programs are available
according to system equipment:
■"External hook-up"
The operating program set at the control unit was
e.g. changed over via an externally connected but-
ton.
Example: In a school, heating demand exists outside
of school times, e.g. for a parents’ evening.
This function cannot be influenced via the control
unit. Once the external changeover no longer
applies, the set operating program becomes active
again.
■"External program"
The operating program set at the control unit has
been changed over by another control device. E.g.,
by your mobile phone with your Viessmann app. You
can change the operating program on the Vitotronic
control unit.
Note
The special operating programs are shown on the dis-
play in alternation with the boiler water temperature.
In the main menu, you can call up the set operating
program under "Information" (see page 20).
