Hi, I have a nest for five years connected to a gas furnace. It’s been working fine all those years.Since yesterday it complains that it wants a y1 cable. There is no y1 cable and there never was. It looks like it now thinks it’s connected to a heat ...

Alex, "can I get a photo of the C wire?">> Sure but how do I upload a photo here? I would have done that but there doesn't seem to be an option to upload anything.

Still weird.i used to have furnace cables to w1 and Rh. Then a wall psu to c and rc. I found a nest manual that says put power to c and RC. Then hookup w1. But i have the second furnace cable that used to go to Rh. What do i do with that?
