Your safe, going to leave the connections to someone who knows what they doing, just wanted to know if it would work before i ordered it. It looks like it's only 5 wires but still not risking it.
Sorry for yet another Nest installation question but before i pay out for the kit i would like to know if its compatible with my boiler.
Current setup:-
Vailliant combi boiler ecoTECpro28.
Vailliant 350 wireless controller.
Thanks in advance
Kev
