Auto-tuning OFF (0): No auto-tuning
1: Auto-tuning for 1st group of PID
2: Auto-tuning for 2nd group of PID
3: Auto-tuning for 3rd group of PID 4: Auto-tuning for 4th group of PID
5 to 8: Perform auto-tuning on a group basis in the same way as 1 to 4
9: Performs auto-tuning to all groups 1 to 8.

“SUPER” function OFF (0) OFF (0): Disable
1: Overshoot suppressing function
Suppresses overshoots generated by abrupt changes in the
target setpoint or by disturbances.
2: Hunting suppressing function (Stable mode)
Suitable to stabilize the state of control when the load varies
greatly, or the target setpoint is changed.
Enables to answer the wider characteristic changes compared
with Response mode.
3: Hunting suppressing function (Response mode)
Enables quick follow-up and short converging time of PV for the
changed target setpoint.
Note: Use “SUPER” function (SC) 2 or 3 in PID control or PI control.
“SUPER” function 2 or 3 is not available in the following controls:
1) ON/OFF control
2) P control (control for proportional band only)
3) PD control (control for proportional band and derivative item only)
4) Heating/cooling control
Do not use hunting suppressing function when control processes
with response such as flow or pressure control.
