Controller regulating may be inaccurate due to change in air rate caused by filter clogging or abnormal quantities in the hopper.
Auto tuning will begin when pressing the up and down triangle buttons at the same time during the drying operation.
(During auto tuning, "At" and the temperature reading will alternately appear every second).
When auto tuning is complete, the unit will return to the original PV display and start PID controlling based on the calculated parameters.
To manually stop auto tuning, repeat step 1.
Note: No alarms can be acknowledged by the controller during Auto-tuning mode. Therefore, any alarms that happen will be noticed after the auto-tuning function is complete. Also, after an alarm occurs, auto tuning cannot be performed again unless the power is reset.
