Thanks so far. Really helpfull!
I can follow you until below:
Do you mean that my actual physical Evohome setup is wrong and TRV’s have been assigned to the wrong zones? Could be, but would that not be unlikely as this would have caused all kinds of strange behavior not? Been running like this for years. Also the HR92 -when you add/replace battery- tells you to what zone it is connected and I always check this.
Or am I mis understanding you?
p.s. zone 09 should have 3 actuators
