Vitotronic 200 and Vitotronic 333 accessories
Note on room temperature hook-up
(RS function) using remote control units
Because of the inertia of underfloor
heating systems, the RS function must
not affect an underfloor heating circuit.
For boilers with a lower temperature
limit, the RS function must not affect the
heating circuit without mixer.

Note on Vitotrol 200 and 300
If required, Vitotrol 200 and Vitotrol 300
can also be used together in one heating
system (one for each heating circuit).

Vitotrol 200 (KM BUS user),
part no. 7450 017
The Vitotrol 200 remote control adjusts
the heating program and the required set
room temperature for one heating circuit
in standard mode, from any room in the
house.
Vitotrol 200 is equipped with illuminated
heating program selection keys and a
party or economy key.
The fault display shows faults on the
control unit.
A remote control unit can be connected
for each heating circuit.
WS function: Installation at any point in
the building.
RS function: Install the remote control
unit in the main living room on an
internal wall opposite radiators, but not
inside shelf units, niches, immediately by
a door or a heat source (e.g. direct
sunlight, fireplace, TV set, etc.).
The integral room temperature sensor
records the actual room temperature and
effects any necessary correction of the
flow temperature as well as a rapid
heat-up at the start of the heating
operation (if suitably encoded).
Connection:
H 2 core lead, maximum cable length
50 m (even if connecting several remote
control units).
H Never route this lead immediately next
to 230/400 V cables.
H A LV connector is part of the standard
delivery
Power supply via KM BUS.
Rated current: 10 mA
Power consumption: 0.2 W
Safety class: III
Protection: IP 30 to
EN 60 529.
Safeguard
through design/
installation.
Permissible ambient
temperature
H in operation: 20 to +40 ºC
H during storage
and transport: 20 to +65 ºC
Room temperature
setting range: 10 to 30 ºC,
adjustable from
3 to 23 ºC or
17 to 37 ºC
The set room temperature for reduced
mode is adjusted on the control unit.
Vitotrol 300 (KM BUS user),
part no. 7179 060
The Vitotrol 300 remote control adjusts
the required set room temperature for
one heating circuit in standard and
reduced mode, the heating program and
the switching times for central heating,
DHW heating and the DHW circulation
pump.
Vitotrol 300 provides an illuminated
display as well as illuminated heating
program selection keys, a party or
economy key, automatic summer/winter
changeover, keys for holiday program,
weekday and time.
A remote control unit can be connected
for each heating circuit.
