The initial start-up and matching of
the control unit to local conditions and
the structural characteristics of the
building, must be carried out by your
heating contractor.
As the user of new combustion equip-
ment, you are obliged to notify the
installation to your local flue gas
inspector (check local regulations).
Your local flue gas inspector will also
inform you (where appropriate) about
work he may be required to perform
on your combustion equipment (e.g.
regular checks, cleaning).
Your heating system is pre-set at the factory
The control unit is preset at the fac-
tory for "heating and DHW", i.e. the
system delivers central heating and
DHW loading (subject to a DHW cylin-
der being installed). Your heating sys-
tem is therefore ready for use.
You may change the factory settings
in accordance with personal require-
ments.
Note
All data is saved in case of power fail-
ure.
Initial start-up

Introduction
5592 453 GB

You can change all settings for your heating system, centrally, at the control
unit.
You can change the room temperature and time program settings for central
heating at the remote control (see separate operating instructions), provided
your system is equipped with a remote control unit.
Opening the control unit

BControl unit flap (open to make
adjustments)
Lift up the cover A, and pivot the con-
trol unit flap Bdown. All boiler con-
trols are located behind the control
unit flap.
Ontheinsideofthecontrolunit
flap B, an abridged version of these
operating instructions can be found
behind a further flap. You may remove
the abridged operating instructions
with the flap.

Position of the gas shut-off valve for
Vitodens 333
1. Check the heating system pressure
on the pressure gauge A: The sys-
tem pressure is too low if the nee-
dle indicates below 0.8 bar. In that
case, top up with water or contact
your local heating contractor.
2. For open flue operation:
Thecombustionairisdrawnfrom
the boiler room.
Check whether the ventilation/
exhaust apertures in the boiler
room are open and unobstructed.
3. Open the gas shut-off valve B.
4. Switch ON the mains power supply;
e.g. at a separate fuse or a mains
electrical isolator.
5. ON/OFF switch "8"C;
standby mode is then shown to be
running by the green indicator (ON
indicator); after a short time the boi-
ler temperature will be displayed.
Your heating system and, if
installed, your remote control unit
are now ready for use.
Heating system shutdown
If you temporarily have no need of your heating system, e.g. during a summer
holiday, switch the system to "standby mode"K(see page 12).
Note
The circulation pump will be started for short periods at regular intervals to pre-
vent it from seizing up. These intervals can be modified by your heating contrac-
tor.
Heating system start-up

Start-up and shutdown
5592 453 GB

Shut down your heating system if you do not intend using it for longer periods
(several months).
Before you shut down your heating system for short or longer periods, it would
be advisable to contact your local heating contractor.
Your heating contractor can then take any necessary measures, subject to
requirements, e.g. for frost protection of the system or to preserve the heating
surfaces.
1. ON/OFF switch "8".
The green indicator (ON/OFF indi-
cator) extinguishes.
2. Close the gas shut-off valve.
3. Switch OFF the mains power sup-
ply; e.g. at a separate fuse or a
mains electrical isolator.
As the system is now at zero volt,
the heating system has no frost
protection.
Note
All settings remain intact.
Starting a heating circuit and DHW heating/loading
Press G.
Central heating and DHW:
&Central heating active.
&DHW will be loaded (subject to a
DHW cylinder or instantaneous

prevent it from seizing up. These
intervals can be modified by your
heating contractor.

In addition to the boiler control unit, a separate room temperature controller (e.
g. Vitotrol 100) must be installed in one of the living rooms, if the heating system
is to be regulated in accordance with the required room temperature.
Make adjustments using the appropri-
ate operating instructions.
Please also note:
&The heating program selector of the
boiler control unit must be set to
"G".
&Set the boiler water temperature
high enough.
&All thermostatic radiator valves in
the room where the controller is
installed must be fully open.
Adjusting the boiler water temperature
If a remote control unit is connected:
Set the room temperature on the remote control unit.
Set the boiler water temperature high enough to be able to achieve the required
room temperature.
Press the following keys:
1. Ofor "set boiler water tempera-
ture"; the current temperature will
flash.
2. a/bfor the required tempera-
ture.

installed).
Thetimeprogramcomprisesfourtime
phases, i.e.
&for central heating, up to four
changes per day between standard
room temperature and reduced

grammed.
&DHW heating and DHW circulation

response time of your heating system
into consideration when adjusting the
time programs. Select correspond-
ingly earlier start-up and shutdown
times.
