Hello,
I have Vokera standard boiler with hotwater tank in attic. The system works with a drayton Timer LP522. So after speaking with drayton, I bought wiser kit2. But it doesn't fire the boiler. Wiser seems to be demanding CH to come on. But boiler isn't firing. I have including the image of the backplate, as it was working with Timer LP522. As I didn't change any wiring, just swapped the LP522 woth Wiser hub 2. So when I go back to LP522, everything works fine. The wire just include Neutral, live, 3 and 4. 1 and 2 not used.
