Thanks Chris....will give it a try later this week.
If it does work I assume that I can connect red to yellow on the stat and cap off blue and earth to override it. Am I correct?
If not by leaving the existing stat of full will the hive run as it should?
Cheers
I am trying to fit a heating only hive to a Worcester 28CDI combi.
The light on the hive comes on but the boiler doesn't fire up.
I have removed the stat but do I need to take anything out of the boiler.
Stat and Control wiring attached
Hoping for some inspiration.
Thanks
