This gain actuates in the system error (proportional control) and is related to stabilization time and

This is responsible for stabilizing the system in the setpoint and canceling the overshoot. It can be

Manualactivation:
When activating the automatic control:
Temperature not steady:
When activating the automatic control and the temperature is not steady:
Theautotuningcan beactivatedeither throughthecontroller keyboardorthrough
theSitrad software. The autotuning will be executed every time the controller
enterstheautomaticcontrolmode(PID).
The autotuning will be executed every time the temperature does not
stabilizeinsidethetimeperiodprogrammedinthefunctionF12. The autotuning will be
executed every time the controller enters in the autotuning mode and when the temperature does not
stabilizeinsidethetimeperiodprogrammedinthefunctionF12.
Ifanerror occursduring the systemdata collection,thecontroller willinterruptthe autotuningandemit
an alarm with the message . Then it returns to the operation mode set before the autotuning
activation.
