This conguration network parameter establishes the default Setpoint for the Leaving Chilled Water
Temperature unless nciDefaults=1 (see Default Values on page 59). When nciDefaults=1, use the
values specied during manufacturing. Refer to the appropriate Operation Manual for suitable variable
values.
