Thank you for answering. Here are pictures of my existing thermostat, the heater panel, and my ac panel.
The problem I’m having is the yellow wire leaving the thermostat doesn’t tie down on the yellow lug on the heater panel. It’s wire nutted to a white wire (out of the picture at heater panel ) that goes out to the ac comp. panel. And the red wire that comes back from the ac comp panel is tied down on “C” on the heater panel. I hope that’s not too confusing.
I can only post one picture per email. I hope you get the rest.
