A setpoint’s value can be changed by first highlighting the item and its value and pressing the SELECT button to highlight just the value. When the value line is highlighted by itself, the value can be adjusted using the up and down arrow buttons. The CANCEL and SET buttons appear at this time. Press the SET button to enter the new value or press the CANCEL button to return the value of the setpoint prior to using the arrows. The displayed value will flash twice to indicated that it has been entered into the setpoint and the pair of setpoint item and value display lines will again be highlighted together.

Operator setpoints can be exited by pressing the STATUS or MAIN MENU buttons. If no buttons are pressed within 30 seconds, the display will return to the CURRENT STATUS screen.
