What it is

The Intergas outside sensor is an NTC thermistor with a nominal resistance of 12kohm, fitted externally to the property to measure outdoor air temperature. It feeds that reading back to the boiler so the control system can adjust flow temperature in line with weather compensation. It is used across the Intergas Combi Compact, Compact, Rapid, Xclusive and Xtreme appliance families.

Signs this part needs replacing

  • Boiler fails to modulate in step with outdoor temperature changes
  • Flow temperature stays fixed regardless of weather conditions
  • Weather compensation fault or sensor error logged at the boiler
  • Unstable or erratic boiler output as outdoor conditions change
  • Flow temperature control that no longer responds to the outdoor reading

Before you order

  • Confirm the appliance model matches one of the fitments listed
  • Check the existing sensor resistance and part number against 203207
  • Verify the sensor wiring and connection at the boiler before replacing the sensor
  • Check the sensor is sited correctly and not affected by direct sunlight or flue discharge
