What it is

The Potterton Input Plug ATF is a plug for the outdoor sensor connection on Potterton Commercial Paramount boilers. It carries the outdoor sensor wiring to the appliance control board, and is listed in Potterton Commercial spares under the description Plug Outdoor Sensor (B9). It is a small plug component rather than a sensor or control unit.

Signs this part needs replacing

  • Outdoor sensor values are not registering, or read erratically, at the boiler controls
  • Weather compensation fails to respond to changes in outdoor temperature
  • Pins or contacts inside the plug body are corroded, burnt or loose
  • Sensor faults appear and clear when the plug or its wiring is disturbed
  • The plug body is cracked or will not latch securely to its mating connector

Before you order

  • Confirm the appliance is a Potterton Commercial Paramount TWO, Three, FOUR or FIVE
  • Check the boiler's kW output against the fit list above
  • Inspect the existing outdoor sensor plug for corrosion, burning or loose pins
  • Confirm the outdoor sensor itself is serviceable before changing the plug
