I have a rental unit with a digital thermostat for the heat and A/C. The display which usually shows the temp, options, and status isn't working (it's blank). I am very familiar with mechanical things and electronics, but unfortunately I know next to nothing about these systems. Can I go buy another thermostat capable of running heat and AC? Can I easily move the wires from the old to the new if I am careful to look at the terminal marking/wire colors?
Thanks for any help.
