Guys came to check on some odd noise coming from the area of my furnace/hot water heater. They figured out the problem and there were no issues. While they were there, I asked if they could install my new programmable/Wi-Fi thermostat. I was reading the instructions and started second guessing myself. They were happy to do and I am glad I asked. They had to connect an additional wire with the furnace wiring. I know it had to be done but I would not have been able to figure it out. Thanks guys.
