I apologize in advance if this is not the correct forum for this. If so, please let me know where I should start.
I am looking to have my central heat pump set up with Ecobee Enhanced. For background, the system has heat and A/C as well as aux heat. There are only two wires being used on the current thermostat, see attached.
I worked with Ecobee support for a few hours and they stated that it may be possible as it appears the hardware needed is present, but would require a technician to do some additional wiring. I tried using their service to locate a contractor in my area, but there are none. I think this is something I may be able to do myself, but I just need to understand what I need to do exactly. All wiring is exposed and accessible and I have the tools to strip, crimp, etc. I was also provided a diagram from them which you can see attached as well. Note: I noticed 2 extra wires in the wall.
Any and all help is appreciated! Thank you.
