EditEd, I see it nowIt’s as easy as removing the red link and installing the black wire in where the right hand terminal where the red link one eg closest to the live terminal
That just denotes the grey wires are being used as neutral wires.John.G - not sure if you've noticed, but there's blue sleeves on the grey wires.
I agree with your post #36What number terminal is this please, from the left.
No that is not consistent with what Diagram C shows. Surely the power needs to be fed into the next terminal along - the 5th position as you are counting?I believe i understand this now
The black wire which enters to the bottom of the Room STAT/Timer block link is carrying power which is carried over through the link into the red wire leaving the bottom and activates the demand for central heating. Hence the boiler firing constantly.
By removing the link and placing the black wire in the 4th position (counting from the earth as number 1) as soon as the thermostats activate, power travels down the black wire and the demand for central heating fires the boiler.
Is my understanding correct?
