result in serious injury.
■Do not smoke. Prevent naked flames and
sparks. Do not 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

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. pet-
rol, solvents, cleaning agents, paints or paper)
can cause deflagration and fire.
Never store or use such materials in the boiler
room or in direct proximity to the heating sys-
tem.
!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
contractor.
Auxiliary components, spare and wearing parts
!Please note
Components not tested with the heating system
may damage the system or affect its function.
Only allow qualified contractors to carry out
installation or replacement work.

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.

These instructions describe the following control units:
■Vitotronic 300, type CM1E and type CM1I
–Weather-compensated control of a multi boiler sys-
tem (cascade)
–Control of the boiler water temperature for the
boiler with Vitotronic 300
■Vitotronic 100, type CC1E and type CC1I
Control of the boiler water temperature for each addi-
tional boiler in the cascade
The Vitotronic 300, type CM1E and type CM1I, are
designed for weather-compensated control of multi
boiler systems (cascades). In addition, these Vitotronic
control units regulate the boiler water temperature of
the boiler which is equipped with the Vitotronic 300.
The Vitotronic control units are factory-configured as
"Boiler and Cascade".
The Vitotronic 100, type CC1E and CC1I, are designed
to control the boiler water temperature of each addi-
tional boiler in the cascade.
Your contractor has configured the Vitotronic control
units accordingly as "Boiler in the Cascade".
In multi boiler systems, boiler water temperatures can
vary between individual boilers. The common flow tem-
perature for the heating system is specified by the
Vitotronic 300, using weather compensation.
In weather-compensated mode, the level of the com-
mon flow temperature is controlled according to the
outside temperature. The lower the outside tempera-
ture, the higher the common flow temperature.
Note
Alternatively, your contractor can configure the
Vitotronic 300 for one of the following application
areas:
■"Single boiler weather-compensated"
This makes the Vitotronic control unit suitable for the
weather-compensated control of a single boiler sys-
tem.
You can find all information on operation in the
"Vitotronic 200" operating instructions.
■"Single boiler constant control"
This makes the Vitotronic control unit suitable for
control of a single boiler system with constant boiler
water temperature.
You can find all information on operation in the
"Vitotronic 100" 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 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.).
Your system is preset
Your heating system is preset at the factory and is
therefore ready for operation following commissioning
by your contractor:
Central heating
■Between 06:00 h and 22:00 h, rooms are heated to
20 °C "Room set temperature" (standard room
temperature).
■Between 22:00 h and 06:00 h, rooms are heated to
3 °C "Set reduced room temperature" (reduced
room temperature, frost protection).
DHW heating
■Between 05:30 and 22:00 h, the DHW is heated to a
50 °C "DHW set 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
Any DHW heating begun before 22:00 h is termina-
ted.
Frost protection
■Your boiler and DHW cylinder are protected against
frost.

Consumption above or below these levels is shown
graphically within the selected time period for com-
parison purposes:
Dark areas: Proportion of energy consumption
for central heating
Light areas: Proportion of energy consumption
for DHW heating
6. Tap e.g. a day or a week on the graph. The energy
consumption for this period is shown as a numeri-
cal value in kilowatt hours "kWh". 10 kWh corre-
sponds to approximately one litre of fuel oil or one
cubic metre of gas.
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.

Energy consumption correction factor
You can enter a correction factor to adjust the dis-
played (calculated) values for energy consumption/fuel
consumption to the actual values (as measured by the
meter in your home). The calculated value is multiplied
by the correction factor. However, due to seasonal cli-
mate conditions and other factors, discrepancies may
still arise.

Vitotronic 300: Central heating and DHW heating energy consumption distribution
Specify the ratio in which your total energy consump-
tion (100 %) is to be split for central heating and DHW
heating. You can estimate the values or establish them
through repeated meter readings (gas meter or oil con-
sumption) over the year.
The values set here are only used in the graphs for
energy consumption ("Fuel consumption").

Special operating programs
The following special operating programs are available
according to system equipment:
■"Screed drying"
This function is activated by your contractor. Your
screed is dried in line with a set time program (tem-
perature/time profile) suitable for the relevant build-
ing materials. Your settings for central heating are
deactivated for the duration of the screed drying.
This function can be altered or cancelled by your
contractor.
■"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, there is a heat demand out-
side of school hours, 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.
■"Holiday program" (see page)
Note
In the main menu, you can call up the set operating
program under "Information" (see page 36).
"External program"
The operating program set at the control unit has been
changed by another control device. You can change
the operating program on the Vitotronic control unit.

Time programs and time phases
In the time programs, you specify what your heating
system should do at what time. To do so, divide the
day into sections. These are called time phases.
Different operating statuses are enabled within and
outside these time phases. The available operating
statuses differ, e.g. through different temperature lev-
els.
You can set up a time program for the following functions:
