[TheMercenary]

We have two thermostats, one for the up stairs, 3 large rooms and a full bath, one for the rest of the house. They are programable and we have ours go down when people are expected not to be there, i.e. kids off to school, week days, higher at waking hours of the night, down at sleeping hours. The programable things have allowed a lot of people to save a bunch of money. If you don't have one, you should.
