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.

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.
