ening poisoning.
■ Shut down the heating system.
■ Ventilate the boiler room.
■ Close all doors in the living
space.

Boiler room requirements
!Please note
Incorrect ambient conditions can
lead to damage to the heating
system and put the safe opera-
tion at risk.
■ Ensure ambient temperatures
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
drying of washing).
■ Never close existing ventilation
apertures.
Ancillary components, spare and
wearing parts
!Please note
Components that are not tested
with the heating system may lead
to damage to the heating system,
or may affect their various func-

Terminology
To provide you with a better understand-
ing of the functions of your Viessmann
control unit some terminology is
explained.
The terms are marked as follows.
Further information can be found
in chapter "Terminology" in the Ap-
pendix.
Your system is preset at the factory
The control unit is preset at the factory
for standard operation.
Your heating system is therefore ready
for operation. You may change the fac-
tory setting in accordance with individual
requirements.
Energy saving tips
Utilise the setting options for the control
unit and remote control (if available).
Central heating
■Room temperature:
Never overheat your rooms. Every
degree of room temperature reduction
saves up to 6 % of your heating bills.
Set your room temperature no higher
than 20 ºC.
■Operating modes:
Introductory information

If you do not require central heating,
select one of the following operating
modes:
– If you do not wish to heat rooms in
summer but require domestic hot
water, set rotary selector "tw" (see
page 11) and turn rotary selector
"tr" to "0".
– If you require neither central heating
nor DHW for a prolonged period, set
rotary selectors "tr" and "tw"to
"0" (see pages 11 and 11).
■Ventilation:
To ventilate, open the windows fully for
a brief time and meanwhile close the
thermostatic valves (if there is no
domestic ventilation system installed).
■Roller shutters:
Close roller shutters (where installed)
at dusk.
■Thermostatic valves:
Ensure that thermostatic valves are
properly set.
■Radiators:
Never cover radiators or thermostatic
valves.
DHW heating
■DHW temperature:
Never set the DHW cylinder tempera-
ture excessively high (see page 11).
■DHW consumption:
Consider showering instead of running
a bath. A shower generally uses less
energy than a full bath.

Operation without room temperature control unit
Further information can be found
in chapter "Terminology" in the Ap-
pendix.
The required heating water temperature
can be set with the rotary selector
"tr" (see page 11).
Operation with room temperature control unit
Further information can be found
in chapter "Terminology" in the Ap-
pendix.
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
Further information can be found
in chapter "Terminology" in the Ap-
pendix.
In weather-compensated mode, the
boiler water temperature is regulated
subject to the outside temperature.
Rotary selector "tr" enables you to
increase or reduce the room tempera-
ture.

1. Check the pressure of your heating
system on the pressure gauge.
Minimum system pressure
0.8 bar.
If the system pressure is too low,
please notify your heating contrac-
tor.
2. With conventional flue operation
(combustion air is taken from the
boiler room):
There must be fixed permanent ven-
tilation into the boiler room.
3. Open the gas shut-off valve.
4. 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
Further information can be found
in chapter "Terminology" in the Ap-
pendix.
If you do not wish to use your boiler for
several days you can switch the unit
off.

Turn both rotary selectors to "0".
Frost protection is now active for the
boiler.
Note
Frost protection for the entire heating
system - see operating instructions for
the room temperature control unit.
Shutting down the heating system
Shut down your heating system com-
pletely if it will not be needed for a long
period of time (several months).
We recommend you contact your local
heating contractor if you are planning to
shut down your heating system for long
periods. Your heating contractor can
then take any necessary action, subject
to requirements, e.g. system frost pro-
tection or preserving the heating surfa-
ces.
1. Close the gas shut-off valve and safe-
guard against unauthorised reopen-
ing.
2. Switch off the ON/OFF switch.
The power to the system is now
switched off.
Note that the system is no longer
frost-protected.
