Hello Everyone. Appreciate any help someone can give me on wiring up a new Vine smart thermostat I just purchased. I've looked up previous posts on the subject, but couldn't find one similar to my setup. Ok, so here goes.My setup is a gas furnace with a separate outside AC unit. Here is a picture of the current terminals in my furnace.Furnace TerminalsOf course my current thermostat doesn't require a C wire so there isn't a one run to that location. Here is a picture of the current thermostat terminals.Current ThermostatMy guess is that both my yellow and common wires are running to my outside AC unit??? I know there are possible workarounds to wiring these thermostats up without a common wire. I would like to that route if possible. I created a quick diagram of what my current setup is along with the terminals on the new smart thermostat.DiagramIf I can only get this to work by running new wiring am I ok having two common wires? One going to my AC unit and one going to my new thermostat.Appreciate any help with this. Thank you!!! via /r/DIY http://ift.tt/2iEsTVu
