SELECT
Setpoints associated with options are described in the OPTIONS
sections.
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 indicate that
it has been entered into the setpoint and the pair of setpoint item and
value display lines will again be highlighted together.
Operator set points 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.
