b. In the equipment schedule, the designer will:
(1) Arrange all control devices by loop function.
(2) Show the unique identifier as the device number.
(3) Name the device function.
(4) Show setpoints, ranges, time schedules, and other parameters.
(5) Show the selected Cv and required close-off pressure for each valve.
13. THE TYPICAL DDC DATA TERMINAL STRIP (DTS) LAYOUT.
For DDC applications, a data terminal strip layout is required to show all connections for inputs and
outputs (also referred to as "points") to the system. Each DDC panel should have a corresponding DTS.
The layout should show the terminals numbered, show the device number (from the schematic) which is
connected to the terminals, have a description of the device and indicate whether each point is an analog
input, an analog output, a digital input, or a digital output. It is a good idea to include 25 percent of the
terminals as "spares". A typical data terminal strip layout is shown in figure 3-18.
