The core set of modules created for all Fan Coil applications provides the zone temperature setpoint and base heating/cooling sequencing logic. Specific selections in the Fan Coil selection tree provide the required Inputs, Outputs, and Network Input connections for the core logic set and integrate the specific Output Controller options for Fan Logic, Heating, and Cooling Coils.

The following is the list of modules created by the core logic.

Network Inputs

  • SYSTEM-MODE: This module is a Network Input for the System Mode Determination Generator that is used during commissioning to drive the system outputs to a specific state. The use is to drive a Water Flush state in State Selection.

  • TUNING-RESET: This module is used to reset the tuning parameters to the default values present after the initial transfer of the application to the device.

See the Network Input Modules section.

Setpoint/Miscellaneous

State Generation

  • System Mode Determination: This module separates out the Water Flush system mode for separate connection to State Selection and passes the remaining system modes to State Selection.

  • Zone Sequencing (FC) (Occupied Sequencing): This module manages the transition between heating and cooling output controllers and determines which device should be operating to control the space temperature.

  • 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.
