The CW Temperature Diff Calc module calculates the condenser water temperature differential across each chiller, and then selects the largest differential and passes that value to the process value of the PID. This module provides a command input, and entering and leaving CW temperatures for each chiller. Based on the inputs, the module passes the largest differential to the output. This module is implemented as a control activity.
