Product Name(s): LanSTARII
Product Description: The LanSTAR II is a supervisory interface (SI) device that polls a secondary control unit network for information, processes that information, then sends control tasks back to the Secondary Control units for execution. LanSTAR IIs also communicate with each other peer-to-peer over an Ethernet network connection. LanSTAR II is TCP/IP compatible, accessible from any internet connection.
Product Application(s): Supports general HVAC end-use devices including air-handling units, VAV systems, chillers/boiler/central plant control, lighting control and distribution systems.

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? Information not provided
How many total trend values can be stored? Information not provided
What is the controllers role in trending? Programming resident within SI gathers and stores trend data on-board. At set intervals, data is sent by the SI to server for archiving.
Can controller be programmed to 'push' data to archive or are trends 'pulled' from controller? Information not provided
When full, does controller automatically send up trend data, overwrite data, or stop logging data? Information not provided
