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-

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.
