Start by making sure the same colors on the terminals on the thermostat back plate. Connect to the same terminals at the furnace. Also with the CT-30. You have to go through the settings while it is in Off mode. To set it up for the type of Furnace and whether you have an a/c or Heatpump.
These thermostats are not that hard to wire up and program. The problem comes into play when the unit that controls the thermostat through the radio, or the radio which can go bad. is a problem.
Also when the program is done on the pad for the thermostat. It has to also load the program into the thermostat.
I own the 3m-50, which is the same as the CT-30. But I use Cloudbeam.com's service and their radio with mine. I had issues with the RTCOA radio and their portal. That is why I ended up going with the other service.
As for the $300 service call for emergency call. That is the norm to have any after work hours or have a company show up on a holiday to fix something.
