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 your
local flue gas inspector of the installa-
tion [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
"Heating and DHW" are already set
up at the factory, i.e. the system deli-
vers central heating and DHW heat-
ing/loading (subject to a DHW
cylinder being installed).
Your heating system 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.
Multi-boiler system
You only require the Vitotronic 333
operating instructions if the boiler is
used in a multi-boiler system in con-
junction with a Vitotronic 333 control
unit. These instructions also include
the operating steps for boiler control.
Initial start-up

Introduction
5592 452 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)

located behind the control unit flap.
On the inside of control unit flap B,
an abridged version of these operating
instructions can be found behind a
further flap C. 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 pressure gauge A: The system
pressure is too low if the needle
indicates below 0.8 bar. In that
case, top up with water or contact
your local heating contractor.
2. For open flue operation: The com-
bustion air is drawn from the boiler
room.
Check whether the ventilation/
exhaust apertures in the boiler
room are open and unobstructed.
3. On Vitodens and Vitopend:
Open gas shut-off valve B.
On Vitoplus:
Open the shut-off valves in the oil
supply lines (at the oil tank and the
filter).
4. Switch ON the mains power supply;
e.g. at a separate fuse or a mains
electrical isolator.
5. Switch ON main ON/OFF switch 8
C;
standby mode is then indicated by
the green indicator (ON indicator);
after a short time the boiler tem-
perature will be displayed. Your
heating system and, if installed,
your remote control unit are now
ready for use.

Start-up and shutdown
5592 452 GB

If, temporarily, you 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 pumps are briefly started every 24 hours to prevent them from
seizing up.
Shut down your heating system if you do not want to use it.
Before you shut down your heating system for short or long 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. Switch OFF main ON/OFF
switch 8;
the green indicator (ON/OFF indi-
cator) goes out.
2. Close the shut-off valves in the oil
supply lines (at the oil tank and fil-
ter) or 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 volts;
the heating system has no frost
protection.
Note
All control settings remain intact.

Only for Vitodens 300 with integral instantaneous water heater.
The instantaneous water heater is held at temperature (standby), as long as the
comfort function is switched ON. Hot water will then be available instantly.
The comfort function can be switched
OFF with /,topreventtheboiler
starting up, thereby saving the energy
required to maintain standby mode
when no hot water is drawn, e.g. at
night.

In addition to the boiler control unit, a separate room temperature controller (e.
g. Vitotrol 100 remote control unit) must be installed in one of the living rooms, if
the heating system is to be regulated in accordance with the required room tem-
perature.
Make adjustments using the appropri-
ate operating instructions.
Please also note:
&"Heating and DHW " Gmust be
selected.
&Set the boiler water temperature
high enough.
&All thermostatic radiator valves in
the room where the controller is
installed must be fully open.
