New Thermostat tripping breaker
Thanks for the replies.
I've got an electric furnace, no humidifier, and I just changed the filter when we moved in a couple months ago, but I'll double check it. The only special thing the thermostat is supposed to do is start early so that you reach your selected temperature at the time you selected for the program. Other than that, no fan delay or anything fancy.
I'm definitely a beginner when it comes to wiring so it might take me a while to try out all of the suggestions, but I'll let you know if anything seems to work.
