The home has multi zone baseboard heat, with the later addition of 2 AC air handlers. First Nest installed fine; the second will only cool or fan.
Directed wiring is Green to G, Y1 to Y1, and RC to Rc (and ignoring the blue jumper between RH & RC).
The Nest thinks there is only AC and no heating. The first Nest allows me specify the heating to be oil, etc. On the second, I am limited to testing and using only cooling functions
