The unit comes with the blue dial of the pot, set in its center position. The term
pot is short for potentiometer. It is a variable resistor. Looking at the picture
above, turning the blue dial clockwise decreases the time and counterclockwise
increases the time.
You will discover that there is a screwdriver slot in the center of the control. A
small 1/8 inch flat blade screwdriver is best to use when adjusting this blue dial.
Care must be taken not to turn the blue control too far. It will not turn or rotate
continuously. The unit is shipped with the control in it mid position.
Whenever you make an adjustment to the blue control you must also press the
