R7/8, R9/10, R11/12: Mixer outputs -> only one of the outputs (1 or 2) can be
switched. It is not possible to switch both outputs at once.
VR 10 sensors must be used for all sensors.
Closing the "DEM" contact ends the heating demand for the relevant heating
circuit.
Four VR 10 sensors are included in the scope of delivery for the VR 71.
