6.3.2 On/Off Control [PAR3 → C-MD → ONOF]
Controls the temperature by comparing PV (Present Value) with SV (Setting Value) and
turning power to the load on or off.
6.3.2.1 Hysteresis [PAR2 → hHYS/OFT/cHYS/cOFT]
 Hysteresis is to adjust control output ON/OFF point in ON/OFF control mode.
ON_Hysteresis sets the output on point and OFF_Offset sets the off point.
 Setting hysteresis too low can result in hunting induced by disturbance (noise,
chattering, etc.). To minimize hunting, set ON_Hysteresis and OFF_Offset values with
consideration to the heater or cooler's capacity and thermal characteristics, the
control subject's response characteristics, the sensor's response characteristics and
installation conditions, and other defining factors.
