My heating wont stop coming on
I noticed in a morning that my heating has started coming on despite it saying it is off on the app. I have deleted all the smart schedules and also turned off the early start yet still it is coming on. The only thing that is set is the Hot Water to come on twice a day for an hour.
The app shows it is off 'until you cancel' but with frost protection (its the middle of the summer in the UK here).
I may be wrong but the heating coming on (well an increase in house temperature shown on the graph) appears to coincide with the hot water coming on.
Anyone got any suggestions please.
