One CCR3 controller connects up to 32 risers in intelligent, electronically controlled modulating control system for return temperature control in one-pipe systems. For buildings with more risers, the system can be easily expanded with additional CCR2 modules. Each riser is equipped with AB-QM, TWA-Z actuator and ESMC surface temperature sensor. One additional ESMC sensor is needed to provide input for supply water temperature.
