Thanks in advance for taking your time. I live in an apartment that has a 2 wire (red&white) thermostat. I want to change to a smart thermostat. I see that behind the wall there were 2 other wires(black&green). So in total there’s White,black,green,red wires. Can I install a ecobee thermostat or nothing is compatible and I should rock this ugly traditional thermostat.
