Switches can be activated by sensors.

  6. Programmable thermostat - Wikipedia

    en.wikipedia.org/wiki/Programmable_thermostat

    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.

  7. Thermostat - Wikipedia

    en.wikipedia.org/wiki/Thermostat

    As illustrated in the use of the thermostat above, all of the power for the control system is provided by a thermopile which is a combination of many stacked thermocouples, heated by the pilot light. The thermopile produces sufficient electrical power to drive a low-power gas valve, which under control of one or more thermostat switches, in ...
