What is a programmable thermostat and how does it work?

The Expert Answer:

A programmable thermostat has a clock and allows you to tell it what temperature you want to set the thermostat at different times of the day on different days of the week. This will let you automatically lower your thermostat setting when you are away at work or asleep in bed.
