Can I get the thermostat with this configuration?
Can you figure out where the blue wire goes at the furnace end of the cable?– ThreePhaseEelJul 7, 2017 at 22:18
It is coiled just like that with the wires in the furnace. Not connected to anything– BryandshawJul 7, 2017 at 22:19
Simply uncoil and strip back the blue wire at the furnace end, then tuck it under the "24V COM" terminal there. Then you can hook it up to the C terminal on your new thermostat and everything should work!
Awesome. Thanks. Will the red on the com be attached to it as well in the furnace? Jul 7, 2017 at 22:22
@Bryandshaw -- yes, the current red wire stays put there (it goes off to your A/C outdoor unit) Jul 7, 2017 at 22:26
