Now, the heating works but only when you turn the water heating on using the programmer. Turning the regular heating on or off on the programmer changes nothing. Now we’re worried heating will cost a fortune as whenever we want to warm ourselves we gotta the heat water also!!
We changed batteries for stat and moved temperature over 20c and set both programs to on but the Honeywelll thing that guess you call RF comes on like it should for 1 second or a few then turns off, when it should stay on.
Got a combi boiler but no heat, I messed with the Drayton timer thing but not sure that stopped the heating. Any ideas of things to try? Attached images of the issue.
