FIGURE 96: SS-L ONBOARD FLOW CHART WORKSHEET PROGRAMMING FOR RESERVED POINTS
5 After the necessary onboard options have been established, determine what
other points should be displayed on the LCD and how they should be displayed.
Some questions to consider would include:
• What database points are required to be displayed?
• What database points would be desirable information and provide value
for an end-user?
• What database points would be desirable for a technician to use for
quick troubleshooting?
• How should the points be displayed? Is an icon preferable and perhaps
more descriptive for some points than showing a value?
• Which points will need to be adjustable from the SS-L?
• Which point is most appropriate for the quick-adjust point? A standard
SS can also adjust this point with a slider or Up/Down buttons.
• Should the secondary-point be enabled? If so, which point is most
appropriate?
For the remainder of the programming example, consider a variable air volume
(VAV) air terminal unit application. Table 21 details the points that will be
displayed on the SS-L.
The valid temperature range of an input for the SS-IO is limited between -40 to 120 °C
(-40 to 248 °F).
