WAIT! I just discovered another breaker in the furnace closet. Will
THIS turn off the thermostat even though it appears to be for the
furnace only? I don't want to just switch it off and on a bunch of
times.


Well, did turning that breaker off, kill the LCD display? Since you
said you had a heat pump, I assume by furnace you mean the
Air Handler? Many thermostats are powered by a stepdown
transformer in or near the air handler. I recommend that
you open the thermostat panel and measure the voltage on
the wires. your new Thermostat MUST match this voltage.
