Fig. 7. Sample Minimum Operator Graphic Display.
Actual values for the temperatures, air flows, and valve and
damper positions and percent fan loads are all shown for the
operator. In addition, the control and logic functions that control
the system are shown. The rectangle in the lower right corner
is a set of selection buttons which allow the operator to look at
additional data. Clicking on one of the buttons produces an
operator display similar to Figure 8.
