What is replacing the DTB2R wall controller for the IRP panel heaters?

Article reference KA-02708

The DTB2R (X-378280) is being replaced by the SWT-IZW (500002283) wall controller. This was due to component shortages for the production of the DTB2R.

The SWT-IZW controller is the same size as the previous DTB2R controller. 

The new SWT-IZW has:

  • Zigbee capability (DTB2R had no comms option in the UK)
  • Control up to 16A of load from the IRP panels connected to it. 
  • Comes with an optional floor temperature sensor probe
  • Open Window detection
  • Adaptive Start 
  • Can run in a continuous, schedule or boost mode.
