I find it convenient, as well as energy efficient, to have the
thermostat automatically turn down the temperature when I am either
asleep, or out of the house. However, you don't need digital to do this.
The standard method invovles two temperature settings, and a clock to
switch between them. The clock is a rotating disk, with slots for little
tabs. You insert a tab at the time you wish the temperature to change,
and when the disk rotates to that time, the thermostat switches from one
setting to the other. The only advantage to the digital versions that I
have seen is that some allow an arbitrary temp setting at each time.
That sounds neat, but I'm not sure how useful it is. I find two settings
sufficient. As for accuracy, who cares about 1/2 degrees?
