Hoping someone can help. Currently have a Drayton MiGenie which was a pleasure to fit due to it being the same fitting as the previous timer, but it's awful and support is always down, so have ordered a NEST V3, but I am stumped. Can anyone point me in the right direction for rewiring? We have an Oil fired Grant boiler for the water and heating. What I'm led to believe is 3 here is for Hot Water and 4 for Central Heating... I put 4 on to 3(Nest) and 3 onto 6(Nest) but no joy...
