Hi,
Fitted a new 3 port valve at the weekend and thought all was well, but not so.
I cant have the CH and HW on together.
If I turn off the power supply then the valve lever moves to rest at centre left.
Turn power on and then select HW, lever will stay where it is and we get hot water.
Turn off HW and turn on CH the valve lever moves all the way to the right hand side and we get hot rads.
Leave the CH on and turn on the HW and the valve just stays in the same position and the rads stay hot but no hot water.
It's as though the valve wont rest in the mid position to allow CH and HW together.
Any ideas what I could have done wrong.
(Tower valve fitted as a straight replacement for the old and a programmable timer in use).
Hope I haven't confused you all.
Thanks,
Dave
