Sorry, the first pic is the current wiring of the EPH but the second picture I took it from a video grab just to show the connections I made on the Drayton back plate. Yes I will be installing wiser at the same location. Am I good to go ahead with the connections you advised above?
Good evening,
I was trying to upgrade the EPH to Drayton wiser kit 1 on a Worcester combi boiler. I have made the connections as indicated in the manual of kit1. However, the CH is not kicking in when called for. The light on the Hub comes on but boiler is not kicking in. Hot water is working...
