The following figure shows how modules in the Control View interact (using Show Involvement in Simulation mode).

Figure 1. Fan Coil Application Example (Show Involvement)

This example shows a Fan Coil application. Based on the network inputs and input readings in this example, the State Tables have determined that the highest priority state generator that should be in Control is Occupied Zone Sequencing (FC/AHU) v51, which is set to the Cooling state. As a result, the Proportional Cooling Control v51 output control is set to Control, which modulates the cooling valve open (CLG-O output).

The following drawing and text further explain the interaction between the cooling modules.

Figure 2. Fan Coil Application Example (Cooling Interaction)

The interactions in this example are as follows:

  • The FLUSHPOS network input provides an input to the Proportional Cooling Control v51 output control.

  • The ZN-SP input provides a Hardware Setpoint input to the ZN-T Setpoint Determination module.

  • The ZN-T input provides input to the following modules:

    • Zone Temperature input to the Occupied Zone Sequencing (FC/AHU) v51 state generator
    • Process Variable input to the Proportional Cooling Control output module
  • The ZN-T Setpoint Determination module provides input to the following modules:

    • Cooling Setpoint input to the Occupied Zone Sequencing (FC/AHU) v51 state generator
    • Setpoint input to the Proportional Cooling Control v51 output control
  • The Occupied Zone Sequencing (FC/AHU) v51 state generator provides the ZNT-STATE input to the State Tables.

  • The State Tables provide the Mode input to the Proportional Cooling Control v51 output control.

  • The Proportional Cooling Control v51 output control provides the Percent Cmd output to the CLG-O output.

The following graphic shows how the modules in the State Generation section provide input to the State Tables and how the state configuration within the State Tables provides input to the modules in the Output Control section. The individual tables in the State Tables are the State Generators and the column headings are the Output Controllers. See the State Tables section.
