Utility Configuration
Create a new class of utilities to use the C.R.O.. The data required to operate the project is extracted from
these controllers. Open the "Class" menu and create a class including the utilities of interest. Utilities are
those with the saturation pressure set-point in common.
Use the Create/Edit/Delete menu items to modify the utility classes. Each utility class can and must be
assigned to one of the CRO engines. The use of the same class applied to multiple engines is not permitted.
Access the menu Operation
Parameters Engine relative to the desired CRO engine to set the configuration
parameters. The C.R.O. module, to better manage the availability of cooling power, in time, modifies the set-
point of the compressor plant (typically, for utilities in normal temperature mode).
-
Execution interval

-
Analysis interval
: indicates for how many minutes, in reverse, the data is to be analysed (operation of
class utilities; in minutes).
-
