I’m in need of a new thermostat and was planning on getting a WiFi version. I have a 5 wire cable going to the thermostat from the furnace but the common is not connected.There is a 2nd wire bundle with 2 wires (AC?) connected to the common and AC1 terminal. There should be no problem with me connecting the blue common wire to the common terminal along with this one correct? I have the other end of it at the thermostat, it’s just not stripped back yet.wiring image via /r/DIY https://ift.tt/3giKif3
