  • Page 6: Product Overview

    Product Overview The technologically advanced TEC Series Temperature and Humidity Controllers feature a Building Automation System (BAS) BACnet MS/TP communication capability that enables remote monitoring and programming for efficient space temperature control. The TEC Series Temperature and Humidity Controllers feature an intuitive user interface with backlit display that makes setup and operation quick and easy.
  • Page 7 The MS/TP Bus requires proper termination and biasing at each end of a segment (a segment is a physically continuous length of wire). Because controllers are not equipped with end-of-line termination, a Johnson Controls® MS-BACEOL-0 End-of-Line Terminator (ordered separately) or similar device is recommended to provide this end-of-line termination.

  • Page 8: Ms/Tp Controller Mapping

    MS/TP Controller Mapping Preparation Before mapping a TEC Series BACnet MS/TP Network Temperature and Humidity Controller into an NAE: 1. Decide which point objects within the controller need to be mapped. Only map the point objects that need to be viewed on a regular basis because excessive mapping lowers system performance.

  • Page 9: Adding Point Objects

    Assisted Definition using Auto Discovery is the easiest way to add a new controller online; however, this method requires that the controller to be added is connected and ready to communicate. IMPORTANT: Because some of the objects may not directly correlate to a previous version (TEC26xx-2), you must rediscover all point objects for the TEC26xx-4 version.

    Troubleshooting Table 2: Troubleshooting Details Symptom Probable Causes Multiple Symptoms Excessive bus errors may be occurring. A device may have been added or changed with a duplicate address (may not be the same address as some devices having problems, and may have happened sometime before the problem was noticed).
