APR17 7:27PM, 82.3 NOTE: Space temperature (AI1) is the default trend log #1. If AI2 is configured for discharge air temperature, that will become the default trend log #2. See Sensor Setup on page To set the desired object to track, press: 1. Up/Down to move among entries. 2. Enter to select. The trend log buffer may be viewed by scrolling down and selecting View Log Buffer. The buffer may also be viewed from the Main Menu by scrolling down to the Trend Viewer (see page 15). NOTE: The BACnet standard for log intervals is hundredths of seconds. The simplified display on the FlexStat converts the value to minutes. However, BACstage and ™ TotalControl do display hundredths of ® seconds but in different ways. For a “10” (minute) interval on a FlexStat display, TotalControl would show “00:10:00.00” (hours:minutes:seconds.hundredths of seconds) and BACstage would show “60000” (hundredths of seconds) instead. NOTE: If applicable to the model, the humidity sensor is AI5 and the motion sensor is BI6, which can also be configured for trend logs.
