This sub could really use a FAQ..

So many of the posts in this sub are very similar.. for example:

-My furnace shuts off the burner while heating and the Ecobee reboots: Your furnace is overheating and hitting the high limit cutoff, which kills the 24V power to the thermostat. Check for a dirty air filter, blocked airflow or a blower that's not moving enough air. Not a thermostat problem in any way.

-My heat pump is cooling when it should be heating or vice versa: the reversing valve wire is set up for the wrong mode in the equipment settings (energize in heat vs. in cool), or not hooked up properly, or your heat pump isn't functioning properly

-My system didn't work right before, I put in an Ecobee and it still doesn't work: why would you think a new thermostat would fix a system issue?

-Can I install an Ecobee in a system with only 2 wires at the thermostat: no, read the instructions

-Posts about issues with new installs really need to include pictures of the wiring at the old thermostat, wiring at the new one, and the connections at the control board
