Information regarding room temperature
hook-up (RS function) when using
remote control units
Due to the inertia of underfloor heating
systems, the RS function should not be
applied to an underfloor heating circuit.
The RS function must only affect the
heating circuit with mixer.

Note on the Vitotrol 200 and 300
If required, the Vitotrol 200 and
Vitotrol 300 can also be used together in a
single heating system, one for each
heating circuit respectively.

Vitotrol 200 (KM BUS user),
part no. 7450 017
In standard mode, the Vitotrol 200 remote
control adjusts the heating program and
the required set room temperature for
one heating circuit from any room in the
house.
The 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 heat source (e.g. direct sunlight,
fireplace, TV set, etc.).
The integral room temperature sensor
captures 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

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 offers an illuminated display
as well as illuminated heating program
selection keys, a party or economy key,
