The Siebe S3 Display Stat can also be programmed on a Host or Secondary Channel of an Internet controller by using a Computrols Wall Stat Interface Board. For instructions, see the Siebe Wall Sensor Interface Board.pdf.

Once you have wired the Siebe S3 to Analog Input 3 of the VAV controller, you are ready to program it in Editor Mode of CBAS. First program the VAV controller, then follow the instructions below.

From the main menu, click on Database, then click Add a Controller. In the first window, give the controller a descriptive name and click Next. Choose Siebe on the left side of the next window and S3 on the right side. Click Next and choose the controller that will be hosting the display stat. Click Next and click Finish in the next window, which lists the Channel and the address on the channel. There is only one address available on the Siebe Channel hosted by a VAV controller.

You can now find the VAV controller in Hardware view. Click on the controller and click Channels. Click on Siebe Channel and click Controllers. You will see the Display Stat listed. Click on the Display Stat and click Points. You will see a list of points with “Add A Point” next to each. These points are standard points, but they need to be added in order for them to show up in Text View. Click Add A Point next to the points you want to use. Give the point a descriptive name and select the one available configuration. Click Add Point Now.

The functions of the points are pre-determined and most are obvious. Here’s a description of some of the less obvious ones:

• Mode: There are 4 modes, which determine what is seen in the display on the Wall Stat itself.
• Temp: Stat display shows the Space Temp
• SPTemp: Display shows Setpoint when in OCCupied status, shows Space Temp when in UNOCCupied status.
• Setpnt: Shows Setpoint all the time
• Altern: Display shows Alternate Display Number, which can be set to anything

Alternate Display Number: Put in the number you want to be displayed when in Altern Mode.

Unoccupied/Occupied Enable: When enabled, allows you to change Occupied/Unoccupied mode from the button on the Display Stat.

If you need to program many identical VAV controllers with S3 Display Stats, you can use a template. Program the first VAV with the Siebe channel, display stat and it’s point. Click on the VAV controller and click Save Controller Database as Template. When programming the subsequent controllers, choose to create the controller from template, instead of a blank database.
