Maureen, FYI, during an autotune session, the firmware will take the setpoint value way over the setting you made for X time and way below your setting for X time to determine the hysteresis of the device being heated and make the necessary PID calculations. Happy new year for you all.

Autotune may not have been able to derive the best PID settings using the 20 second cycle time. Repeat the steps 3 and 4 three times within 60 secondsand If everything is OK, all led should switch to ON as below picture. Optional Event function, using PLC or switches to switch between 2 different set temperatures. But what happen with DTC? Fans and Thermal Management.
