Furnace will not listen to thermostat
I have a tempstar 2 stage furnace. I just installed a new programmable thermostat. The furnace will not kick on when the temperature drops below the program temperature. It will work when I turn the curcuit breaker off and then on. Why won't the furnace listen to the programmable thermostat?

Did you buy a 2 stage T-stat for replacement?
You can't rely on wire colors. Need to match up the terminals/functions of each thermostat.
Might need a jumper added for the "R" terminal between Rc and Rh. Usually it's preinstalled.
You mentioned it will only work when you cycled the furnace. Your furnace maybe in a fault situation.
