    - You already finished a PID Auto-Tuning successfully before - You didn’t change the PID parameters by hand in the meantime - You didn’t unplug the cable between the TED4015 and your thermal setup (e.g. changing the mount). To save time, the new quick PID Auto-Tune process tries only to readjust the PID parameters calculated before.
