Pump running and boiler fired up all the time

[Notebook]

Hi
I just had to replace the 3 way valve and the pump.

The valve works fine - heating just the water or ch rads if selected.

I changed this yesterday. However last night was aware that I think that the pump was continually running and also the boiler running.
I don't think this is correct?
Is this controlled by a stat on the tank?

also

I turned off isolation valves above and below the pump to change it and also left (top of tank) and right of the valve(pipe going under floorboards).
There is also another going from the bottom of the tank to in between the pump and valve.

all these I have turned back on. Is this correct?

any help appreciated

would say you have a wiring problem.

would say you have a wiring problem.

In what way?
What should I check?

You need to check the wiring that you've done against a wiring diagram. You may find that there are compatibility issues between new and old components. It all depends on the age of the system and the components that you have swapped.

you are picking up permenent live feed the wiring will need redoing sounds like you have by passed the stats so if you arnt any good with a multimeter you will need to get a enginner because without me being thier i dont exactly know where you have gone wrong but easy to do when swapping because some are different to others in the layout

new on hear gonna have to look at posting dates i think if it is still running his gas bill will be biger than a factory did the same trick the first valve i fitted years ago took me ages to figure it out but the hardest lessons learnt are the best in the long run cos you dont do it again or do you lol
