Good Morning. I believe the Nest2 is capable of handling multi stage heat and cool. Are you installing this thermostat right now?

If system was initially set up with enough wires from furnace to stat, it should be wire for wire terminal designations, however, you may need a "common" wire for the Nest stat. I would suspect if the furnace has been updated recently that it was only wired for single stage because you did not have enough wires run from furnace to thermostat. Could this be the case?
