ENGINEERING MANUAL OF AUTOMATION CONTROL
Figure 8 shows how dynamic data can assist an operator.
This display provides the operator/engineer with the actual
operating values, at that instant, embedded in the sequence of
operations and allows the operator to adjust setpoints and review
results in real time. This is one of many operator displays that
can be designed to facilitate operator understanding and control
of IAQ.
