(4) ON/OFF control
In ON/OFF control, the manipulated output (MV) is turned on and off depending on whether
measured value (PV) is larger or smaller than set value (SV). Differential gap setting can prevent
relay contact from on or off repetition around set value (SV).
(5) Heat/cool control
In heat/cool control, only one module enables heat and cool control. For example, this is effective
when cool control is required in extruder cylinder temperature control.
