Circuit Hub
Model
1250.3US
The circuit hub is a communication center between the return
temperature sensor, the control unit, and the circuit's powerhead. Each
circuit hub has an integrated return temperature sensor. The return
temperature sensor on the circuit hub goes into the return sensor port.
The circuit hub transmits the return temperature to the control unit. The
control unit uses this information to determine how to prioritize and/or
distribute heat to each circuit in the system. After the control unit
analyses the system parameters, it transmits control information back to
each circuit's powerhead.
