HVAC Control System
HVAC here stands for Heating, Ventilation and Air Conditioning. Thus, a HVAC control system applies regulation to e.g. a heating. Usually, a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then, the control system draws a conclusion what action has to be taken (e.g. start blower).

—Michael D. Stephens. “On Sinai, There’s No Economics,” New York Times (Nov. 13, 1981)
“Daily life is governed by an economic system in which the production and consumption of insults tends to balance out.”
