in the end i dont think a digital controller in and of itself
saves all that much money, but if you get a programmable one i think you
can
eliminate much of the 'oops i forgot to turn the heat down' factor.

That is the only real advantage I can see. I don't have central AC, but for
heat, I like the fact that it comes on 15 minutes before I wake up and it
goes down in two steps during the day. I save at least 5%, maybe 10% with
no forgetting to turn it down.. It does old the temperature closer thanthe
old round Honeywell.
