I have a two zone system. See pictures of boiler, at the zone terminals and at both thermostats.
How can I install the wiring for nest? Hoping to have 3rd gen and 2nd gen on a zone each. Providing power to it on my wall near the front entrance. Or is it possible to have just one nest and it work the entire house, eliminating the zones?
Please let me know if anyone can help me set it up!
