This video is part of a series on the parts of a PID Loop and how you can adjust them to tune the PID Loop for more effective control over various automation devices, such as a Humidifier Steam Valve.

In Part 2 we start seeing the automatic adjustments of the PID Loop to assist in making the input equal the set point. These adjustments are slow and gradual and help prevent a back and forth or overshoot condition.
