Room Temperature Sensor,
Separate room temperature sensor as supplement to the
Vitotrol 200A and 300A; to be used if the Vitotrol 200A
or 300A cannot be installed inside the main living room
or in a suitable position where the unit can capture and
adjust the temperature.
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.).
Connect the room temperature sensor to the Vitotrol
200A or 300A.

Mixing Valve Actuator Kit
The mixing valve actuator is mounted directly on the
Viessmann ¾ to 2½" mixing valve.
The mixing valve actuator is a motor-driven control unit.
The rotational direction is reversible.
The mixing valve actuator comes with a plug-in connector
for a heating circuit pump, supply temperature sensor
(strap-on sensor with 7 ft. (2.1 m) connecting cable),
power supply connecting cable 9 ft. (2.7 m) and a
connecting cable 9 ft. (2.7 m) for the KM-BUS Expansion
Module.
