After changing the cylinder stat I now have a issue with the 3 way valve. It works fine apart from when the hot water has been the last thing on. When the heating is the next to call on its own it goes to mid way and just stays there. If you then turn the hot water off on the controller it continues to heating and the boiler then starts. Guessing its a wiring issue.
Recap
Heating only fine
Hw only fine
Heating and Hw fine
Hot water not calling but on heating calls valve moves from hw to mid position and just stays there.
Any ideas on wiring checks?
