Is there a general rule for how far you should set back your
thermostat? If you will be away from the house for over 8 hours,
should you set it back 5, 10, 15 degrees? Currently I have mine set to
75 when we are home and 68 when we leave. We are gone around 10-12
hours per day. This is a brand new home with a seperate systems for
upstairs and downstairs.
