Morning All After bit of advice
We were due a wireless thermostat fitting by a (unnamed company )
due to how my system is they could not wire it in needed a live feed
After they went things were not right after they had poked around . boiler would not fire
My dads a sparky although works on industrial machinery when we opened up we found the grey wire was loose we have now fitted it to the correct connector or so we think . my dads offered to come back and have another look but he works alot and has no time at the minute .
The boiler fires
But symptoms are if the boiler fires for HW all is fine . if CH comes on the valve moves to CH and stays there will not move to mid position or back to HW .
So if the cylinder stat calls the boiler fires but it just heats the radiators due to the three port valve stuck over in CH
If turn the system off three port valve returns to HW
position
Any ideas?
