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.
