PURPOSE AND OBJECTIVE Monitor the different parameters of the
different modules attributed to the chilled water air conditioning system.
The computer program shall be in a passive mode, i.e., it shall display and indicate the trouble or abnormality experienced by the air conditioning system and recommend the proper correction of such trouble.
Trouble shooting will still be made manually.
