Hey all, new here. Thinking of installing an Emerson Sensi Touch thermostat and have a few questions, hoping someone can give me their opinion on before I start. I need a C wire for it which is not currently connected to my thermostat (pic#1), but I have a ton of unconnected wires just behind the wall (pic#2). Based on the photos below, just wanted to confirm that the red wire that has no connection at the thermostat (pic#2), would be the C wire that is shown connected at the furnace connections (pic #3)? Just want to make sure I get it right?
1. Thermostat Wiring
2. Thermostat Loose Wires
3. Wiring at Furnace
Also I have an HVAC in the house, any extra wiring to add the HVAC control (the control beside the thermostat with the hot/cool dial and the off/on/20:40 buttons) to the new thermostat? I haven't popped this control off the wall yet to see the wires so was wondering if its possible first. Thanks in advance, gonna go and checkout the forum more in the meantime.
