APPENDIX C

Building Interface — The 30RAN chiller can be inter- faced with multi-vendor control systems through 3 levels of inter-operability using BAClink, DataPort™, or DataLink™ controls. BAClink controls function as a gateway between a SCN and a BACnet™ system to facilitate the passing of data from the SCN to BACnet. The Sterlco DataPort control is an interface device that allows other HVAC control systems to “read only” values in system elements connected to a SCN

communication bus. The Sterlco DataLink control is an inter- face device that allows other HVAC control systems to read and change (“read/write”) values in system elements connected to a SCN bus. Both DataPort and DataLink controls request data from a specified SCN system element and translate this data into ASCII characters off network. Information from the 30RAN chiller control to support interface are listed in the following tables.
