Nest Thermostat Wiring

[strangedad5]

Need help wiring.   I assume OB->OB, G->G, R->R, Y->Y?   Where does Rc, U1, and U2 go?

Hi strangedad5,

Thanks for reaching out. In some cases the U terminals control humidifiers or other accessories. Your Nest Thermostat 2020 doesn't support this but you could wire it like what you mentioned and it should work. You could click on this link to learn more about this.

Thanks,

Edward
