Hi, I'm new!
Have been moved in my new house a few months now and the heating did work fine. Have been in the process of chaning the programmer (to one with independent HW and CH times) and rewiring it (it was right but all wrong if you know what i mean and a complete mess - done by a guess what goes hear theory)
But i now have a problem, CH works on its own, so does HW on it own - both work togther but the 3 port valve sits in the middle clicking and moving the lever a m/m each way constantly.
I believe all is wired correctly - 3 people have checked this, plus it is the same with both the old and new programmers. I got my self data sheets for all the stats etc, and the 3 port valve. So im questioning why a 3 port valve can go wrong from just sorting everythng else...
Ideas would be super, thanks!
