Operation
Radiator controller HR 50
With temperature sensor HCF 22
The temperature sensor HCF 22 transmits the room temperature
to the Hometronic Manager. The HCM 200d displays the room
temperature.
The Hometronic Manager transmits the resulting setpoint (set-
point plus its own offset) to the radiator controller.
A detailed example on this is found in Chapter "Temperature
control with HCM 200d and storey controller" from Page 20.
