F​rom the sounds of it your problem is that the board inside the Honeywell Pro has fried and you will need to replace the whole unit sadly. Any chance its still covered under warranty? Honeywell is really great when it comes to replacing there products. They are a great company that stands behind there products.

Do you think it is the thermostat, or the Interface module, or both? I'm guessing just the thermostat since I have voltage at the R and C wires. Thanks Travis.

I am thinking the problem i just with the thermostat. Its the only thing that makes sense since you are getting voltage at the wires.
