Frequently asked questions
How is the automatic calculation (AT) started and stopped?
AT is started by selecting the AT function; it stops automatically when certain conditions are met, such as reaching temperature limits or after a timeout.
What is the purpose of the start‑up calculation (ST)?
ST calculates and sets PID constants automatically when power is applied or when switching from STOP to RUN, helping the controller respond quickly.
