System Manager/Zone Coordinator User’s Manual 21
428516-YUM-B-0908
The System Manager and Coordinator also collect samples for the last 10 changes of
the following outputs:
• RTU fan status (On/Off)
• Cool1 to Cool4 (On/Off)
• Heat1 to Heat3 (On/Off)
You can view this data in tabular format sorted by time and date, with the most current
samples listed first. The data that is displayed for each sample includes:
• Time and Date
• Trended value
• Units (if the trended value is an analog value)
The trend information is current at the time you requested the data. The System Man-
ager or Coordinator replaces old trend data with the newest data as it becomes avail-
able. The trend data cannot be printed or exported. Also, the data does not refresh
dynamically as it is viewed.
Display Units
The user interface can display data using the English or Metric format. Table 8 shows
the analog value units. These units apply wherever the value is displayed or modified.
You can specify which system of units to use for the site; see Selecting Display Units
on page 33.
