What it is

The Ideal 175733 is an OpenTherm wiring harness kit for Ideal Commercial appliances.

It is listed in the Ideal Spares range under Cables, Leads & Wiring Harnesses.

Signs this part needs replacing

  • The OpenTherm thermostat loses communication with the appliance
  • The boiler holds a fixed flow temperature instead of modulating on demand
  • Heating demand is intermittent or does not reach the appliance at all
  • Connector pins or plug housings on the existing harness are loose, corroded or damaged
  • Fault codes relating to control or communication wiring appear on the appliance

Before you order
