6.4.8 TREND TAB
The Trend Logger will access the Remote Site and Acquire the site information stored in the controller.
This information is stored in a comma separated value file. The information stored is the Zone
Temperature, Zone Humidity, OutDoor Temperature, OutDoor Humidity, Unit #1 Supply Air
Temperature, Unit #2 Supply Air Temperature, Mechanical Run Time, and Economizer Run Time. The
controller will store all of these values once per hour and will hold up to 128 hours of data. Once the
data register has been filled, the new data will overwrite the oldest data in the register. The Data should
be acquired at least every 128 hours to make sure that none of the data is overwritten without being
stored.
To save or graph the stored information, click on the graph button at the side of the desired information.
A graph of the stored information will appear and it can then be printed or saved to a file of your choice
for later reference.
