PIC System Components Ð The Product Integrated Control (PIC) is the control system on the chiller. See Table 1. The PIC controls the operation of the chiller by moni- toring all operating conditions. The PIC can diagnose a prob- lem and let the operator know what the problem is and what to check. It promptly positions the guide vanes to maintain leaving chilled water temperature. It can interface with aux- iliary equipment such as pumps and cooling tower fans to turn them on only when required. It continually checks all safeties to prevent any unsafe operating condition. It also regulates the oil heater while the compressor is off and the hot gas bypass valve, if installed. See Fig. 6-10 for the lo- cations of sensors, transducers, and other devices controlled and/or monitored by the PIC system.

The PIC can be interfaced with the Carrier Comfort Network (CCN) if desired. It can communicate with other PIC-equipped chillers and other CCN devices.

The PIC consists of 4 modules housed inside one of 3 lo- cations: the control center, the power panel, or the starter cabinet. The component names and the control voltage of each location are listed below (also see Table 1):
