Hi everyone,I just moved into a new construction home and I’m still getting settled in. I tried to install a Nest thermostat but it wasn’t working. I tested a second nest and same results. I used a multimeter and saw I got nothing when I tested the R and C terminals. So I went to the furnace control board and took a look. Sure enough, my blue common isn’t connected to anything. I was just going to connect it to the C terminal but there are two white wires already there. My board seems like it has extra wires or at least wires I wasn’t expecting. Can I just connect the blue wire to the C terminal or could that short things out? Most of the nest related stuff I’ve come across hasn’t helped me much.
