I am looking at buying a new thermostat and I am trying to decide which to buy the Honeywell 8000 or the White-Rodgers 90 series (1F95-1277).

I am also trying to determine what the difference is between the two White-Rodger 90 series models (1F95-1277 and the 1F97-1277). I know what the literature says, but I don't know that a multi-stage system is, or what a heat pump is. I have a regular house with central air and an air-conditioner (no air-cleaning system).

If someone could help me out I would greatly appreciate it.

Regards,
Jonathan M.
