    Continously running pump

    This is a picture of the untouched y plan. From the bottom 1,2,3,4 were too the stat so I removed these and linked 1 and 4 together. I know it's hard from Pic but I imagine you experienced engineers will probably see any issue straight away. This is how it's been for at least a decade

    Central heating pump on continuous

    By moving the the doubled up live to x14 the pump started operating normally. The RT does go to the room stat. As chased it through. So thanks andyb you are correct. The installer just missed the x14 because he usually installs worcester but couldn't get one in time. Thanks for all replies...

    Central heating pump on continuous

    Thanks for reply. I think it needs a spdt timer relay fitting to control the pump unless the new boiler can be retrofitted.

    Central heating pump on continuous

    So how do I rectify as heating engineer doesn't know. The only boiler connections are live neutral earth and RT. What is different between this boiler and old boiler. I never saw the connections on the old potterton. Would it of has a pump feed on it?

    Central heating pump on continuous

    Hi thanks for reply. The link has been removed and the heating is working on programmer as you would expect. The pump is even on if I disconnect the programmer because the L and RT cable in the boiler are fed to connectors behind programmer no to the programmer itself.

    Equipment understairs.

    Equipment understairs.

    Thanks for reply. Dartlec I have looked at the data sheet and the issue I have is as you say TNCS is not mentioned so is it suitable? I might contact Wylex directly. To ask the question. The main fuse I believe is 80amp to to be 100 percent would need to have fuse pulled.

If its deemed dno equipment then I know they have different...
