Thermostat low voltage issue
Hello please be gentle. I am sure this is a DIY/rookie mistake. So I am replacing some drywall and I planned to move my Nest thermostat to the next stud over for better access. I unhooked the 5 low voltage wires and pulled them out of that stud bay and moved to the next. I hooked it back up and now the Nest is saying that the red(power) wire does not have power so the nest will not work. What happened or what should I have done? I think maybe a mistake I made is I did not tape the open wires when I pulled them through the stud holes. Did I or was I not supposed to arc those wires together. I thought with low voltage it would not be aproblem? SHould I have turned off the power before I did this? It kicked an error on the nest that said (e74 Rc no power)
