Document Edition 3.1 Page 1 of 35APPLICATION GUIDEDelta Network Sensor Thermostat: BACstat IIDNS-24, DNT-T103, & DNT-T221Document Edition 3.1Product DescriptionThe BACstat II is an intelligent 4-button room sensor/thermostat with acustom 3-value, 96 segment LCD display that is used with Delta’s productline of BACnet Application Controllers. It is capable of displaying a widerange of digital or analog values, and is capable of communicating on Delta’sproprietary LINKnet network or directly on a BACnet MS/TP network.When connected to an Application Controller on a LINKnet network itprovides programmable remote sensor and expanded I/O capabilities to thecontroller. When connected on an MS/TP network it functions as anindependent BACnet sensor device or a small local controller.The DNS-24 model does not have additional I/O and built-in control strategies, while the DNT-T103 has 1extra input, 3 binary outputs and a number of built-in application control strategies. The DNT-T221 has 2extra inputs, 2 analog and 1 binary outputs and built-in application control strategies. As a result, the DNT-T103 and DNT-T221 BACstats are capable of simple stand-alone control when directly connected on anMS/TP network. When connected to a LINKnet network, the additional I/O may be MUXed or otherwisecontrolled from the Application Controller it is connected to.ContentsOTHER RELEVANT DOCUMENTS ................................................................................. 2IMPORTANT INFORMATION.......................................................................................... 2SETUP & CONFIGURATION ............................................................................................ 3N ETWORK COMMUNICATIONS .......................................................................................... 3D EVICE C ONFIGURATION (K EYPAD ) ................................................................................. 3S ERVICE T OOL MODE (K EYPAD) ...................................................................................... 6I NPUT CALIBRATION ......................................................................................................... 8I NPUT S CALE R ANGES ....................................................................................................... 8SOFTWARE & PROGRAMMING ..................................................................................... 9O BJECTS ............................................................................................................................ 9P ROGRAMMING ............................................................................................................... 10CONTROL FUNCTIONS................................................................................................... 12O VERVIEW ...................................................................................................................... 12S OFTWARE LOOP CONTROLLER ...................................................................................... 13S ETPOINTS ...................................................................................................................... 16CONTROL D IAGRAM ........................................................................................................ 17CONTROL A PPLICATIONS (M UX , VAV, VVT, HPU, FCU, RAD , H UM) .......................... 18O UTPUT F UNCTIONS & TYPES ......................................................................................... 26OWS FUNCTIONS ............................................................................................................. 30APPENDIX (LCD Object Property Values & Programming Notes).............................. 32
