Target group
These instructions are exclusively intended for author-
ised 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 electrician.
■The system must be commissioned by the system
installer or a qualified person authorised by the
installer.
Regulations to be observed

■Statutory regulations for the protection of the envi-
ronment
■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

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.
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 your
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.
■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 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.
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.
Instruct system users that subsequent modifications to
the structural conditions 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.
Apertures for supplying combustion air must be
non-closable.
Extractors
Operating appliances that route exhaust air outdoors
(cooker 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 route exhaust air outdoors 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.

The Vitotrol 100 type UTDB-RF2 maintains a constant
room temperature by means of its integral room tem-
perature sensor in conjunction with the wireless
receiver. During the set periods, there is a changeover
between operation with standard "Comfort" room
temperature and operation with reduced "Eco" or
"Reduced" room temperatures. DHW is heated during
the set periods.
Installation location
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 (radiators, direct sunlight,
fireplace, TV set, etc.).
■Wireless reception (good communication with the
wireless receiver) must be possible (see page 11).
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 11).
(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.
