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)
