Vitotrol 200A
One Vitotrol 200A can be used for every heating circuit
in a heating system. The Vitotrol 200A can regulate one
heating circuit and up to two remote controls may be
connected to the control unit.
KM BUS Participant
The Vitotrol 200A remote control regulates the required
set room temperature in standard mode, from any room
in the house.
- Party and economy mode can be enabled via keys
- Only for heating circuit with mixing valve
Fitted room temperature sensor for room temperature
hook-up
WS function:
Installation anywhere in the building.
RS function:
Note: Never activate the RS function for underfloor
heating circuits (inertia). In heating systems with
a heating circuit without mixing valve and heating
circuits with mixing valve, the RS function must
only affect the heating circuit with mixing valve.
Room temperature hook-up:
Installation in the main living room on an internal wall
opposite radiators. Never install inside shelf units,
recesses, 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 corrections
of the supply temperature as well as a rapid heat-up
at the start of the heating operation (if appropriately
programmed).
