All Central Cooling applications use the core logic listed as follows:
OA-T (Outdoor Air Temperature): This module is loaded if the Outdoor Air Temperature (OA-T) optional sensor is not selected.
SYSTEM-EN (System Enable)
TUNING-RESET: This module is used to reset the tuning parameters to the default values present after the initial application transfer to the device.
See the Network Input Modules section.
PMPDOWN-TIME (Pump Down Time): This floating constant (Constant) delays the pump stop command allowing the primary cooling equipment to maintain flow after shutdown.
Chilled Water System Enable (System Enable): This module enables and disables other modules based on the SYSTEM-EN and Outdoor Air Temperature values.
PID Tuning Reset: This module forces every output controller to reset the Proportional Band and Integral time of every PID to default values based on current process ID.
