Just throwing in my 2 cents, if you have a heat pump you might want to  
avoid radically changing your thermostat settings. Heat pumps have a  
fairly limited ability to react to large changes in temperature, and  
they work more efficiently within a small range. For example, in the  
winter if you have your temperature set at 60F during the day but then  
68F when you get home, on a cold day there may not be enough residual  
heat outside to allow the unit to reach 68F in a reasonable amount of  
time, so it will use the "backup" heat source, usually electric  
induction, which just blew any savings you may have gained by lowering  
the temperature in the first place.
