Advanced control functions
ON/OFF control
When process value (PV) is below the set value (SV), output is turned on and the heater is energized as shown below. When PV is SV, output is turned off and the heater is de-energized. In this way, output is turned on/off repeatedly with respect to the SV to keep the temperature constant.
This method of control is called "on/off action" (or "two positions actions").
PID AUTO TUNING
PID parameters are automatically set by the controller's measurement and computation function.
