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.
