Initial Setup

To set up the DDFCUC, perform the following tasks:

  1. Add device to the job

  2. Create areas and channels as required

  3. Run the FCUC Configuration Wizard

  4. Configure plant

  5. Configure temperature control - PID or staged control scheme

  6. Configure temperature control properties for the selected modes

  7. Run FCUC diagnostics

  8. Configure inputs

  9. Configure temperature aggregation and broadcast (if applicable)

To complete the configuration process, you will need to consider the following factors:

  • Area climate specifications

  • Selection of areas to be controlled

  • Environmental and usage factors

  • User interface control buttons

  • Number and location of controllers (typically one per area)

  • Plant hardware interface, capacity, and limitations

  • Lag times between control signal and effect

  • Lower-energy solutions (window coverings, passive ventilation, etc.)

  • Control scheme to be used (PID/staged)

Add Device to the Job

When System Builder and the DDFCUC are both connected to the network, you can add the controller to the job by clicking sb icon insert device from network Insert Devices from Network. To create an offline device, click sb icon insert device from list Insert Device from List.

Create Areas and Channels

To establish default settings, area and channel must be assigned to each DDFCUC.

In Areas view, create an HVAC area and channel for the controller, then create additional channels as required for the fan and GPR outputs.

FCUC Configuration Wizard

This wizard simplifies initial setup by walking you through the main settings required by the controller. Regardless of whether you use the wizard, you can manually configure all settings and properties in the device’s System view editors.

Run the FCUC Configuration Wizard (System View):

  1. Right-click the DDFCUC and select sb icon configuration wizard FCUC Configuration Wizard…, or select the DDFCUC and press Alt+W.

  2. Configure the properties for each section of the wizard and then click the Finish button.

  3. Click sb icon save to device Save to Device (F12).

If GPR is set to Heating or Cooling with the PID control scheme in effect, then the General Purpose Relay must be used for heating/cooling purposes and NOT the hot/cold water valve.

Switch Input Functions

Input 1-4

  • Airflow sensor

  • Dirty air filter

  • Drip tray overflow

  • Energy holdoff

  • Hot water on cold valve

  • Preset

  • Smoke detector trip

  • Temperature Sensor

  • No function

In addition, the wizard sets the following default values:

  • For all logical addresses, set Join 0xFF and BLA Disabled.

  • Set all input switches' Logical Area/Channel to match the controller.

  • Set Cold/Hot valves configuration type to Floating.

  • Enable all Faults/Signals and set their Auto restart count to Infinite Restart Attempts.

  • All other properties will match the default (factory set) values.
