Additional Information
* Items in NV memory are not lost upon power or battery failure. Other types of NV memory such as EPROM, NOVROM, etc. do not directly impact system performance.
Can trend data be stored in this controller? Yes
How many total trend values can be stored? The user has complete control over how trend memory is used, including how many points are trended, how often the trend samples are taken, how many samples are stored in the module, and whether or not the trend data will be backed up to a historical database on the server. For example; a UNI/32 controlling 29 VAV zones, with each trending 8 points, sampling every 5 minutes, and storing 144 samples (12 hrs) in the module before uploading to the historical database generates a total of 232 trended points or 33,408 trend samples in the UNI and leaves 760k memory free for additional trends over and above what's being used for the control logic and the existing trends.
What is the controllers role in trending? Information not provided
Can controller be programmed to 'push' data to archive or are trends 'pulled' from controller?
When full, does controller automatically send up trend data, overwrite data, or stop logging data? Information not provided
