Control
Most modern fan heaters have a power setting to determine power output. Some also have a thermostat which switches off heating when the desired ambient temperature is reached. They do not maintain perfect room temperature control, since
- the thermostat is usually attached to the body of the heater, and senses temperature there.
- the basic bimetal thermostats usually used have significant hysteresis.
- Remote sensors and thermostats with less hysteresis are available but are less common, as they are more expensive and the basic fan heater is satisfactory for most purposes.

Famous quotes containing the word control:
“All industries are brought under the control of such people [film producers] by Capitalism. If the capitalists let themselves be seduced from their pursuit of profits to the enchantments of art, they would be bankrupt before they knew where they were. You cannot combine the pursuit of money with the pursuit of art.”
—George Bernard Shaw (1856–1950)
“The child knows only that he engages in play because it is enjoyable. He isn’t aware of his need to play—a need which has its source in the pressure of unsolved problems. Nor does he know that his pleasure in playing comes from a deep sense of well-being that is the direct result of feeling in control of things, in contrast to the rest of his life, which is managed by his parents or other adults.”
—Bruno Bettelheim (20th century)
“The basic tool for the manipulation of reality is the manipulation of words. If you can control the meaning of words, you can control the people who must use the words.”
—Philip K. Dick (1928–1982)
