Honeywell electronic thermostat in a store. Heating and cooling losses from a building (or any other container) become greater as the difference in temperature increases. A programmable thermostat allows reduction of these losses by allowing the temperature difference to be reduced at times when the reduced amount of heating or cooling would not be objectionable.
Consider investing in a "smart" thermostat. Because many can connect to smartphones via mobile apps, smart thermostats allow homeowners to program their thermostats while they're away or even set ...
A thermostat exerts control by switching heating or cooling devices on or off, or by regulating the flow of a heat transfer fluid as needed, to maintain the correct temperature. A thermostat can often be the main control unit for a heating or cooling system, in applications ranging from ambient air control to automotive coolant control.

An actuator may be driven by heat through the expansion that most solid material exhibit when the temperature increases. This principle is commonly used, for example, to operate electric switches in thermostats. Typically, a (non-electronic) thermostat contains a strip with two layers of different metals, that will bend when heated.
