In ON/OFF control algorithm, temperature value is tried to keep equal
to set value by opening or closing the 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 above.
