Setpoints are user-adjustable variables in the
controller logic that can be set using the OPERATOR
SETPOINTS screen.
The name and value of each of the setpoints listed
below can be seen on the screen by moving the list up
and down using the arrow buttons.
Setpoints associated with options are described in the
OPTIONS Section 3.6.
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 to the value of the setpoint prior to using the
arrows. The displayed value will flash twice to indicate
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.
