I wanted to stop by and see how I could help.
Thanks for assisting, Mel.
@Tiffanyle, We appreciate you posting a picture of your zoning panel. If you look closely, you'll notice that there's a COM section on the bottom left. Usually, that terminal is intended for the C wire connection. It might be complicated to install a C wire; we'd suggest contacting an HVAC technician for the installation.
Please let us know if you need more help.
I'm checking in to make sure that you've seen our response. Please let us know if you have any additional questions or concerns before we lock this thread in 24 hours.
