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

When activating the automatic control and the temperature is not steady:

Theautotuningcan beactivatedeither throughthecontroller keyboardorthrough

enterstheautomaticcontrolmode(PID).

The autotuning will be executed every time the temperature does not
