What it is

The THI outside sensor is a Hamworthy component intended for use with Cranborne boilers. It is mounted externally to read the outside air temperature and feed that reading back to the boiler's control system. That information allows the boiler to modulate its output in line with changing external conditions.

Before you order

  • Confirm the appliance is a Hamworthy Cranborne model before ordering.
  • Check the existing sensor's part number against 573406015 where it is still legible.
  • Verify the sensor cable route and mounting position are accessible for the replacement.
  • Check the boiler's control documentation for any commissioning steps required after fitting a new outside sensor.
