If you smell flue gas
Danger
Flue gas can lead to life-threat-
ening poisoning.
■ Shut down the heating system.
■ Ventilate the boiler room.
■ Close all doors in the living
space.
In case of fire
Danger
Fire creates the risk of burning
and explosions.

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-
tions.

The commissioning and matching of the
control unit to local conditions and build-
ing characteristics, as well as instructing
the user in the operation of the system,
must be carried out by your heating con-
tractor.
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]. 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, clean-
ing).
Your system is preset at the factory
The control units are factory-set for cen-
tral heating and DHW heating:
■ Vitotronic 100:
" "
■ Vitotronic 300-K:
"Heating and DHW"
Your heating system is therefore ready
for use.
Central heating
■ Between 6:00 and 22:00 h, the rooms
are heated to 20 °C "Set room tem-
perature" (standard heating mode).
■ Between 22:00 and 6:00 h, the rooms
are heated to 3 °C "Set reduced room
temp" (reduced heating mode, frost
protection).
■ Your heating contractor can make fur-
ther settings for you during commis-
sioning.
You can change any settings individu-
ally at any time to suit your require-
ments (see chapter "Central heating").
DHW heating
■ Between 5:30 and 22:00 h, the DHW
is heated to 50 °C "Set DHW temper-
ature". Any installed DHW circulation
pump is on.
■ Between 22:00 and 05:30 h, the DHW
cylinder temperature will not be rehea-
ted. Any installed DHW circulation
pump is off.
■ Your heating contractor can make fur-
ther settings for you during commis-
sioning.
You can change any settings individu-
ally at any time to suit your require-
ments (see chapter "DHW heating").
Frost protection
■ Your boiler, heating circuits and DHW
cylinder are protected against frost.
Wintertime/summertime changeover
■ This changeover is automatic.
Time and date
■ The day and time were set by your
heating contractor during commission-
ing.

the appendix contains the chapter "Ter-
minology" (see page 52).

Each boiler is equipped with its own con-
trol unit for constant temperature opera-
tion. These control units are regulated by
a higher weather-compensated cascade
control unit.
■ Control unit for constant temperature
operation on the boiler:
Vitotronic 100
■ Higher weather-compensated cas-
cade control unit:
Vitotronic 300-K
You can change all settings for your
heating system centrally at the control
unit programming unit.
You may also make such changes at the
remote control units, if your system is
equipped with such units.
Remote control operating instruc-
tions
The settings at the Vitotronic 100 are
described in these operating instruc-
tions. You do not need the operating
instructions provided with these control
units.

1. Check the heating system pressure
at the pressure gauge. The system
pressure is too low if the indicator
points to the area below 1.0 bar or is
below the red band. In this case, top
up with water or notify your local heat-
ing contractor.
2. Check that the ventilation apertures
of the installation room are open and
unrestricted.
Note
With open flue operation, the com-
bustion air is drawn from the installa-
tion room.
3. Open the shut-off valves in the oil
lines (at the tank and filter) or open
the gas shut-off valve.
4. Switch ON the power supply, e.g. at
a separate MCB/fuse or a mains iso-
lator.
5. Switch ON the ON/OFF switches at
all Vitotronic 100 and at the
Vitotronic 300-K (see chapter "Con-
trols").
After a short time, the following is
shown on the display:
■ Vitotronic 100: the standard display
(see page 11)
■ Vitotronic 300-K: the standard
menu (see page 13)
The green ON indicator illuminates.
Your heating system and, if installed,
your remote control units are now
ready to operate.
Note
On every Vitotronic 100, " " must be
selected, otherwise the Vitotronic 300-K
cannot use the corresponding boiler to
produce heat.
