I have a very old Honeywell 3 port valve in my house which has stopped working.
From what I read they normally default to hot water if they fail, but mine is the opposite. The manual lever goes up to Central Heating, but when CH is off and HW on, it doesnt spring back.
I've tried to free it up by jiggling the spring and adding lots of WD40, but no joy.
Unfortunately replacing it is a massive ball-ache. It's located behind the tank between pipes - and being an old one the head is not seperate.
So, my question is...
Is there a way I could wire it so it stays in the mid position (HW and CH both)? That would be fine for winter as I always need both on.
