A setpoint’s value can be changed by first highlighting the item
and its value and pressing the SELECT button to highlight just the

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
