I had a new Worcester boiler fitted and ever since had an issue with my Cosy wireless stat, that's always worked fine.
It fires up the heating and water, but when the temperature drops below what is set on the stat it doesn't fire the boiler/heating back up.
Does anybody have any ideas?
The person who fitted the boiler has been a couple of times and I've had no luck as yet. He's changed the 3 port valve as at first I couldn't get hot water, without the heating on. Now I can just this issue with temperature drop.
Thanks for your help.
