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:
“He took control of me for forty-five minutes. This time I’ll have control over him for the rest of his life. If he gets out fifteen years from now, I’ll know. I’ll check on him every three months through police computers. If he makes one mistake he’s going down again. I’ll make sure. I’m his worst enemy now.”
—Elizabeth Wilson, U.S. crime victim. As quoted in People magazine, p. 88 (May 31, 1993)
“For the mother who has opted to stay home, the question remains: Having perfected her role as a caretaker, can she abdicate control to less practiced individuals? Having put all her identity eggs in one basket, can she hand over the basket freely? Having put aside her own ambitions, can she resist imposing them on her children? And having set one example, can she teach another?”
—Melinda M. Marshall (20th century)
“Being a parent is such serious business that we dare not take it too seriously. Children are inherently funny. So are parents. We all are at our funniest when we are desperately struggling to appear to be in control of a new situation.”
—Lawrence Kutner (20th century)
