above 0 ºC and below 35 ºC.
■ Prevent air contamination by
halogenated hydrocarbons
(e.g. as contained in paints,
solvents or cleaning fluids) and
excessive dust (e.g. through
grinding/polishing work).
■ Avoid continuously high humid-
ity levels (e.g. through frequent

The commissioning and matching up of
the control unit to local conditions and
the building characteristics must be car-
ried out by your heating contractor.
As the user of new combustion equip-
ment, you may be obliged to notify your
local flue gas inspector of the installation
[check local regulations]. Local flue gas
inspectors will also inform you [where
appropriate] about work they may be
required to perform on your combustion
equipment (e.g. regular checks, clean-
ing).

Operation without room temperature control unit
The required heating water temperature
can be set with the rotary selector
"tr" (see page 10).
Operation with room temperature control unit
Please make any adjustments to the
connected room temperature control unit
using the relevant operating instruc-
tions.
Note
The heating water temperature must be
set sufficiently high using the rotary
selector "
tr
" for the desired room tem-
perature to be reached.
Weather-compensated mode
In weather-compensated mode, the
heating water temperature is regulated
subject to the outside temperature.
Rotary selector "tr" enables you to
increase or reduce the room tempera-
ture.

We recommend you contact your local heating contractor if you are planning to start
up a heating system that has not been used for a long period.
1. Check that the heating system is
full.
2. Open the gas shut-off valve.
3. Switch on the ON/OFF switch.
Your heating system and room tem-
perature control unit (if connected)
are now ready for operation.
Shutting down the heating system
Switching the Vitodens off with frost protection
If you do not wish to use your boiler for several days you can switch the unit off.
r
1. Turn rotary selector "tr" to "0".
2. Turn cylinder temperature controller
(if provided) to "0" or lowest setting.
Note
Frost protection is now active for the
boiler.
Frost protection for the entire heating

Shutting down the heating system
Shut down your heating system completely if it will not be needed for longer periods
of time (several months).
We recommend you contact your local heating contractor if you are planning to take
your heating system out of use for longer periods. Your heating contractor can then
take any necessary action, subject to requirements, e.g. system frost protection or
preserving the heating surfaces.
1. Close the gas shut-off valve and safe-
guard against unauthorised reopen-
ing.
2. Switch ON/OFF switch OFF.
The power to the system is now
switched off.
Note that the system is no longer
frost-protected.

Note
If a room temperature control unit is con-
nected, use this unit to set the desired
room temperature (see page 7).
If central heating is active, the display
shows "r".
Switching off:
Turn rotary selector "rt" to "0".
Domestic hot water
If a DHW cylinder is part of your heating system, select the DHW temperature at the
DHW cylinder controller.
Select the DHW temperature in accordance with your personal requirements (e.g. for
showering).

All appliances may be cleaned with a
commercially available domestic clean-
ing agent (non-scouring).
Inspection and maintenance
The inspection and maintenance of a heating system is prescribed by the Energy
Savings Ordinance [EnEV - Germany] and the DIN 4755, DIN 1988-8 and EN 806
standards.
Regular maintenance ensures trouble-free, energy-efficient and environmentally
responsible heating. For this it is recommended you enter an inspection and main-
tenance contract with your heating contractor.
Boiler
Increasing boiler contamination raises
the flue gas temperature and thereby
increases energy losses. All boilers
should therefore be cleaned annually.
Logbook
Please ensure that you have a Logbook
supplied with your appliance. This Log-
book should be completed by your instal-
ler to verify that the correct installation
and commissioning procedure was fol-
lowed.
Failure to complete the Logbook may
result in difficulties should a problem
arise with your appliance during the
guarantee period. This Logbook forms
part of the industry's Benchmark code of
practice for the installation, commission-
ing and servicing of central heating sys-
tems.
All Gas Safe Registered Installers carry
a ID card and have a registration num-
ber. Both should be recorded in your
Logbook. You can check your installer is
Gas Safe registered by calling GasSafe

You can also save energy by taking the following steps:
AC
B
D
■ Correct ventilation.
Briefly open window A fully and at the
same time close the thermostatic
valves B.
■ Never overheat rooms;
endeavour to achieve a room temper-
ature of 20 °C; you can save up to 6%
on your heating bills for every degree
you reduce your room temperature.
■ Close roller shutters (where installed)
at dusk.
■Adjust thermostatic valves B cor-
rectly.
■Never cover radiators C and thermo-
static valves B.
■ Utilise the setting options offered by
control unit D.
■ Only activate the DHW circulation
pump if DHW is being drawn.
■ Controlled DHW consumption: A
shower generally uses less energy
than a full bath.
