Programmable thermostats, first introduced over 100 years ago , are a type of thermostat that allows the user to set a schedule for different temperatures at different times. Most programmable thermostats also have a hold feature which suspends the schedule and effectively turns the thermostat into a manual thermostat. The idea of the scheduling feature is that users will set a warmer or cooler te...

Smart thermostats are similar to programmable thermostats in the sense that they have a scheduling feature that allows users to set different temperatures for different times of the day. In addition to this feature, smart thermostats implement other technologies to reduce the amount of human error involved with using programmable thermostats. Smart thermostats incorporate the use of sensors that d...

It is important to work systematically and rule out potentia...

Summing up what we've discovered already, you can see that all mechanical thermostats (all non-electronic ones) use substances that change size or shape with increasing temperature. So bitmetallic thermostats rely on the expansion of metals as they get hotter, while gas bellows work using the expansion of gases. Some thermostats go further and use the change in state of a substance from liquid to ...

Most of us spend only a half to a third of our time at home: the rest of the day, we're either at work or traveling there. Typically, we'll have a programmer or thermotstat at home that switches the heating on or off either according to the time of day or the inside temperature. But that's a crude system at best. By default, to avoid a cold home, a lot of us just turn the heating up high, wasting ...
