Manual Set Point Adjustment
Adjust the set point by opening the controller cover and moving the set point indicator until the line on the set point
indicator is over the desired value on the process pressure scale. Move the indicator to the right to increase the set
point and to the left to decrease it. Adjusting the set point does not affect the proportional band setting.
