What it is

The cable tree is a wiring harness for the 24V DC roomstat connection on Glow-worm Flexicom boilers. It carries the low-voltage control signal between the roomstat and the boiler's control electronics. The assembly is supplied as a complete harness with the cable tree connectors already fitted.

Signs this part needs replacing

  • The roomstat fails to call for heat or the boiler does not respond to a demand
  • Intermittent or unstable heating control traced to the low-voltage roomstat circuit
  • Visible damage to the harness, such as chafed, pinched or broken conductors
  • Loose, corroded or heat-damaged terminals at the harness connectors
  • Faults that persist after the roomstat and its connections have been checked

Before you order

  • Confirm your boiler model against the fitment list above
  • Check the existing harness routing and connector layout before removal
  • Verify the appliance uses a 24V DC roomstat connection
  • Inspect the roomstat and its terminations first, as faults can originate there rather than in the harness
