Thermostat control with boiler feedback via HR 80 and
HC60NG (valve position-based)
With need-based boiler feedback, all HR 80s send information on
their valve position to the Hometronic Manager. When necessary,
the Hometronic Manager sends the boiler request to relay
HC60NG, which switches the boiler on.
