For each device, in addition to its name, the amount of cold call is also indicated. "Ch." corresponds to the

compressor start-ups, while "On/Off" corresponds to the call of the eventual electronic expansion valve.

These values are used to calculate the cold call percentage of the algorithm.

Each line corresponds to a different moment in which the C.R.O. algorithm has sent a new set-point to the

plant: this set-point is shown on the right, below the "Set" column.

From the previously described window, press "Graph Results" for a graph displaying the same information.

The user is asked to indicate the graphic tools with which to display the graph.

The graph shows the collected data for the selected period; together with the plant set-point as a dotted line.

With C.R.O. deactivated, the central set-point would be a horizontal line: the areas above this fixed set-point

and floating set-point are energy saving.

The plant set-point is illustrated in the first graph of the following image, whilst in the graph below, the energy

consumptions relating to the same period are shown.
