In ON/OFF control algorithm, temperature value is tried to keep equal to set value by
opening or closing completely last control element. ON/OFF controlled system, temperature
value oscillates continuously. Temperature value’s oscillation period or amplitude around set
value changes according to controlled system. For reducing oscillation period of temperature
value, a threshold zone is formed below or around set value and this zone is named hysteresis.
Action of control output is described with figures below.
