Safety instructions explained
Danger
This symbol warns against the risk of injury.
!Please note
This symbol warns against the risk of material
losses and environmental pollution.
Note
Details identified by the word "Note" contain additional
information.
Target group
These instructions are exclusively intended for quali-
fied contractors.
■Work on gas installations may only be carried out by
a registered gas fitter.
■Work on electrical equipment may only be carried
out by a qualified electrician.
■The system must be commissioned by the system
installer or a qualified person authorised by the
installer.
Regulations to be observed
■National installation regulations
■Statutory regulations for the prevention of accidents
■Statutory regulations for environmental protection
■Codes of practice of the relevant trade associations
■All current safety regulations as defined by DIN, EN,
DVGW, TRGI, TRF, VDE and all locally applicable
standards

Safety instructions for working on the system
Working on the system
■Where gas is used as the fuel, close the main gas
shut-off valve and safeguard it against unintentional
reopening.
■Isolate the system from the power supply, e.g. by
removing the separate fuse or by means of a mains
isolator, and check that it is no longer live.
■Safeguard the system against reconnection.
■Wear suitable personal protective equipment when
carrying out any work.
Danger
Hot surfaces can cause burns.
■Before maintenance and service work, switch
OFF the appliance and let it cool down.
■Never touch hot surfaces on the boiler, burner,
flue system or pipework.
!Please note
Electronic assemblies can be damaged by elec-
trostatic discharge.
Prior to commencing work, touch earthed
objects such as heating or water pipes to dis-
charge static loads.
Repair work
!Please note
Repairing components that fulfil a safety func-
tion can compromise the safe operation of the
system.
Replace faulty components only with genuine
Viessmann spare parts.

Auxiliary components, spare and wearing parts
!Please note
Spare and wearing parts that have not been tes-
ted together with the system can compromise its
function. Installing non-authorised components
and making non-approved modifications or con-
versions can compromise safety and may inva-
lidate our warranty.
For replacements, use only original spare parts
supplied or approved by Viessmann.
Safety instructions for operating the system
If you smell gas
Danger
Escaping gas can lead to explosions which may
result in serious injury.
■Do not 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 or electricity supply utility 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 doors to living spaces to prevent flue
gases from spreading.
What to do if water escapes from the appliance
Danger
If water escapes from the appliance there is a
risk of electrocution.
Switch OFF the heating system at the external
isolator (e.g. fuse box, domestic distribution
board).
Danger
If water escapes from the appliance there is a
risk of scalding.
Never touch hot heating water.
Condensate
Danger
Contact with condensate can be harmful to
health.
Never let condensate touch your skin or eyes
and do not swallow it.
Flue systems and combustion air
Ensure that flue systems are clear and cannot be
sealed, for instance due to accumulation of conden-
sate or other causes. Ensure an adequate supply of
combustion air.
Inform system users that subsequent modifications to
the building characteristics are not permissible (e.g.
cable/pipework routing, cladding or partitions).
Danger
Leaking or blocked flue systems, or an inade-
quate supply of combustion air can cause life
threatening poisoning from carbon monoxide in
the flue gas.
Ensure the flue system is in good working order.
Vents for supplying combustion air must be non-
closable.
Extractors
Operating appliances that extract air to the outside
(extractor 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.
Fit an interlock circuit or take suitable steps to
ensure an adequate supply of combustion air.

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.
Product information
The Vitotronic 200, type CO1E control unit is designed
for weather-compensated control of single boiler sys-
tems.
The Vitotronic control unit is factory-configured as
"Single boiler weather-compensated".
In weather-compensated mode, the flow temperature
level is controlled according to the outside tempera-
ture. The lower the outside temperature, the higher the
flow temperature. This means that more heat is provi-
ded for central heating and domestic hot water heating
on cold days, than on warmer days.
Note
The Vitotronic control unit can alternatively be config-
ured for one of the following application ranges:
■"Single boiler constant control"
The Vitotronic control unit is then operated as a sin-
gle boiler system control unit with constant boiler
water temperature: See "Vitotronic 100" installation
and service instructions.
■"Boiler in the Cascade"
The Vitotronic control unit is then used to control the
boiler water temperature of a boiler in a multi boiler
system: See "Vitotronic 300" installation and service
instructions.

!Please note
Excessive DHW temperatures can damage the
DHW cylinder.
If the system is operated in conjunction with a
DHW cylinder, ensure that the maximum permis-
sible DHW temperature is not exceeded. If nec-
essary, install suitable safety equipment.

Danger
Incorrect wiring can lead to serious injury from
electrical current and result in appliance dam-
age.
■Route LV leads < 42 V and > 42 V/230 V~
cables separately.
■Only strip the minimum of insulation from
cables as close as possible to the terminals
and bundle tightly to the corresponding termi-
nals.
■Secure cables with cable ties.
When connecting external switching contacts and on-
site components, observe the insulation requirements
of IEC/EN 60335-1.
!Please note
Electronic assemblies can be damaged by elec-
trostatic loads.
Before beginning work, touch an earthed object
such as a heating or water pipe to discharge any
static.
