CCR3 Temperature Controller
Brand: Danfoss
The CCR3 Controller is an electronic controller for return temperature control in risers in one-pipe heating system based on supply temperature signal.
With CCR3 controller one-pipe heating system becomes efficient variable flow system with riser’s flow control based on heat demand.
CCR3 is dedicated to be used with AB-QM automatic balancing & control valve equipped with thermo Actuators type TWA-Z (NO) and remote temperature sensors type ESMC.
Features- Improved room temperature control
- Eliminated overheating of the building
- Reduced heating cost with payback time less than 4 years
- Remote control of all temperature setting (no need to have direct access to risers)
