risk of injury.
!Please note
This symbol warns against the
risk of material losses and envi-
ronmental pollution.
Note
Details identified by the word "Note" con-
tain additional information.
Target group
These instructions are exclusively inten-
ded for qualified contractors.
■ Work on gas installations must only be
carried out by a registered gas fitter.
■ Work on electrical equipment must
only be carried out by a qualified elec-
trician.
■ The system must be commissioned by
the system installer or a qualified per-
son authorised by the installer.
Regulations
Observe the following when working on
this system:
■ Statutory regulations regarding the
prevention of accidents
■ Statutory regulations regarding envi-
ronmental protection
■ The Code of Practice of relevant trade
associations
■ All current safety regulations as
defined by DIN, EN, DVGW, TRGI,
TRF, VDE and all locally applicable
standards
aÖNORM, EN, ÖVGW-TR Gas,
ÖVGW-TRF and ÖVE

If you smell gas
Danger
Escaping gas can lead to explo-
sions which may 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 or electricity
supplier and your local heating
contractor from outside the
building.
■ Shut off the electricity supply to
the building from a safe place
(outside the building).

If you smell flue gas
Danger
Flue gas can lead to life threat-
ening poisoning.
■ Shut down the heating system.
■ Ventilate the installation site.
■ Close all doors in the living
space.
Flue systems and combustion air
Ensure that flue systems are clear and
cannot be sealed, for instance due to
accumulation of condensate or other
causes. Ensure a sufficient supply of
combustion air.
Instruct system users that subsequent
modifications to the building characteris-
tics are not permissible (e.g. cable/pipe-
work routing, cladding or partitions).
Danger
Leaking or blocked flue systems,
or an insufficient supply of com-
bustion air can cause life threat-
ening poisoning from carbon
monoxide in the flue gas.
Ensure the flue system is in
proper working order. Apertures
for supplying combustion air
must be non-closable.
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.
Fit an interlock circuit or take suit-
able steps to ensure a sufficient
supply of combustion air.
Working on the system
■ Where gas is used as the fuel, close
the main gas shut-off valve and safe-
guard it against unintentional reopen-
ing.
■ Isolate the system from the power sup-
ply (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 recon-
nection.
Danger
Hot surfaces can cause burns.
■ Before maintenance or service
work, switch OFF the appli-
ance 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 electrostatic dis-
charge.
Before beginning work, touch
earthed objects, such as heating
or water pipes, to discharge static
loads.

Repair work
!Please note
Repairing components that fulfil a
safety function can compromise
the safe operation of the sys-
tem.
Faulty components must be
replaced with original Viessmann
spare parts.
Auxiliary components, spare and
wearing parts
!Please note
Spare and wearing parts that
have not been tested together
with the system can compromise
its function. Installing non-author-
ised components and making
non-approved modifications or
conversions can compromise
safety and may invalidate the
warranty.
For replacements, use only orig-
inal spare parts supplied or
approved by Viessmann.

The Vitotrol 100 type UTDB-RF2 main-
tains a constant room temperature by
means of its integral room temperature
sensor in conjunction with the wireless
receiver. During the selected periods,
there is a changeover between operation
with standard room temperature "Com-
fort" and operation with reduced room
temperature "Eco" or "Reduced". DHW
is heated during the selected periods.
Installation site
Vitotrol 100
■ Installation in the main living room on
an internal wall opposite radiators
■ Approx 1.5 m above floor level
■ Not near windows or doors
■ Not on shelves or in recesses
■ Away from heat sources, such as
– radiators
– insolation
– fireplace
– television
■ Wireless reception (good communica-
tion with the wireless receiver) must be
possible (see page 13).
Never install further control devices in
this main living room. If the radiators are
equipped with thermostatic valves, these
must always be fully opened.
Wireless receiver
■ Installation in the boiler.
■ Wireless reception must be possible
(see page 13).
Subject to the material used and the
thickness of walls and ceilings, the
range may be up to 30 m.
Note
Conductive metallic materials have a
strong negative effect on reception.
