PID auto tuning is a function for the controller to automatically measure characteristics of control target
in order to calculate and set best PID values. Auto tuning gives ON/OFF control output based on the
setting values and calculates PID integer by measuring hunting cycle and amplitude.
Enter setting values(SV) in the constant-value control mode; run; press button window; and press
temperature or humidity auto tuning button to run auto tuning. With the auto tuning setting, if zone
selection is set to AUTO, the calculated PID value of zone is automatically saved.
If zone selection is set to MANUAL, it is saved to a specified PID zone.
●
How to Auto Tuning
- If the auto tuning is not completed within 24 hours, it is abandoned. However,
the control operation is continued.
- If the auto tuning is forcibly ended, PID value is maintained same as before the forcible end.
