The thermostat on an iron works by turning the power to the heating coils on and off. This regulates the temperature of the iron, keeping it at the desired temperature. Usually, the thermostat is a bi-metallic switch, which moves in response to heat. The knob changes the pressure on the switch, which changes the amount of heat required to turn the switch off.
Hypothalamus
Yes, a thermostat opens and closes in response to the temperature in the cooling system under normal conditions. If it is sticking it can cause fluctuations in the radiator coolant temperature.

Thermostats operate in a way so as to control (through their extensions) temperature about a selected setpoint. Some are fixed and some can have the setpoints selected. There must be some "sensor" in the device that will react to changes in temperature. The response of the "sensor" is used to direct intervention to affect control of the temperature. Wikipedia has a good post on the different types of thermostat and how they work. A link is provided.

I just called DirecTV and asked them to tell me who regulates them in California and received "we are not allowed to give out that information" as the response. When I inquired as to why they could not give out that information, the response was "it's a policy, sir." Dead end.
Fever (also known as pyrexia, from the Greek pyretos meaning fire, or a febrile response, from the Latin word febris, meaning fever, and archaically known as ague) is a frequent medical sign that describes an increase in internal body temperature to levels above normal. Fever is most accurately characterized as a temporary elevation in the body's thermoregulatory set-point, usually by about 1-2 °C. Fever differs from hyperthermia. Hyperthermia is an increase in body temperature over the body's thermoregulatory set-point, due to excessive heat production or insufficient thermoregulation, or both. Carl Wunderlich discovered that fever is not a disease but a symptom of disease. The elevation in thermoregulatory set-point means that the previous "normal body temperature" is considered hypothermic, and effector mechanisms kick in. The person who is developing the fever has a cold sensation, and an increase in heart rate, muscle tone and shivering attempt to counteract the perceived hypothermia, thereby reaching the new thermoregulatory set-point. A fever is one of the body's mechanisms to try to neutralize the perceived threat inside the body, be it bacterial or viral
