pump running continuously

If the pump is not connected to the pump feed then it’s not an internal fault with the boiler. With a voltage indicator you could check the wiring an see where the pump is picking it’s feed up from when it shouldn’t be.

Ok,got that,but the wiring is correct as per the potterton wiring plan,I'm thinking back to this wireless receiver thermostat thing again,plus I didnt take my voltage indicator pen down with me I don't trust it....I once had a cable where I could see both cut ends and the pen still lit up....

As I wrote that I realised that a faulty valve or this receiver could provide the pump with a supply,
