3 TEC22x6(H)-2 Series LONWORKS Network Thermostats with Two Outputs, Dehumidification Capability, and Three Speeds of Fan Control Technical Bulletin Network Variables (NVs) and Configuration Properties (CPs) List Table shows the NVs and CPs for the TEC22x6-2 Series thermostats. Each Network Variable Input (NVI), Network Variable Output (NVO), and Network Configuration Input (NCI) has a reference number, and some objects have a subcategory number. The Sub column lists the thermostat s Enumeration (Enum) options for each NV or CP. The Byte column shows the byte number for each of the entry fields in the ncigenopts Status/Command screen. Note: When viewed using a LONWORKS network configuration tool, the ncigenopts screen is a 25 byte field, one for each entry field.

Note: This NVI coordinates the Space Comfort Controller with any node that needs to control the heat/cool changeover of the unit. It is overridden by nviapplicmode, unless nviapplicmode is HVAC_AUTO. If nviapplicmode is HVAC_AUTO, then nviheatcool determines the effective mode of the unit. See Table 3 for information on using the nviheatcool, nviauxheatenable, and SeqOpera variables.

The Binary Input (BI) object type status is available even if the configuration is set to None. 8

19 Commissioning the Thermostat Using a LONWORKS Network Configuration Tool A thermostat must first be commissioned using a LONWORKS network configuration tool before it can be added to the LON Integration Network Automation Engine (NAE). This process implements the initial configuration and assigns the Neuron ID of the thermostat. Understanding LONWORKS Network Configuration Tools Differences LONWorks network configuration tools use different numbering schemes in their Status/Command screens. In the ncigenopts Status/Command screen, Metasys system Connectivity to LONWORKS network (MCL) Tool begins its first data entry location with Byte 0, whereas Lonwatcher begins with Byte. The byte entry location number depends on which Tool you are using. Figure shows the ncigenopts Status/Command screen in MCL Tool on the left, with the equivalent Lonwatcher screen on the right. Figure : MCL Tool and Lonwatcher Status/Command Screens Table 7: LONWORKS Network Configuration Tool Terminology Differences LONWORKS Network Configuration Tool ncigenopts Screen MCL Tool Byte 0 to Byte 24 Lonwatcher Byte to Byte 25 LonMaker Tool Not directly changeable 9

20 Changing the Thermostat s Settings Using a LONWORKS Network Configuration Tool Once a thermostat is configured and online, you can use a LONWORKS network configuration tool to change its default settings. This means you do not have to go to the thermostat and manually make the changes. To change most of the thermostat s configuration properties: Note: See Table 4 for Lockout command information.. Using a LONWORKS network configuration tool, open the the thermostat s ncigenopts Status/Command screen. Note: See Table 7 for the byte entry location numbering differences. 2. From Table 9 find the desired configuration property and enter the corresponding value into its respective byte location in the ncigenopts Status/Command screen. Note: Some configuration properties require you to enter a range number in a specific byte location, followed by a corresponding value in the next byte location. You must enter both the range number and value before commanding the thermostat. 3. Enter additional configuration property changes if desired. 4. Command the thermostat. The new configuration changes are implemented. Service Pin To broadcast the thermostat s Neuron ID over the LONWORKS network, simultaneously press and hold the Up Arrow and Down Arrow for 5 seconds. The Status LED flashes once every 5 seconds to indicate the thermostat s Neuron ID is being broadcast on the LONWORKS network. For manual entry, the Neuron ID is also on a label on the Echelon chip under the thermostat cover. Status Light-Emitting Diode (LED) The status LED shows the operational status of the thermostat. The Status LED is a small green light under the thermostat cover (under the LONWORKS daughter board on the left edge when facing the thermostat). Table 8: Status LED Explanation Status LED Condition Explanation Continuously On Flashing at a 0.5 Hz Rate Continuously Off The thermostat does not have an application loaded in its memory. The thermostat has an application loaded in its memory but is unconfigured. Use a LONWORKS network management tool to bind the thermostat to a LONWORKS network. The thermostat has an application loaded in its memory and is bound to a LONWORKS network. 20

21 Adding a Thermostat to the NAE Once a thermostat has been commissioned, you must add it to the NAE before you can map its points. To do this, select the LONWORKS Integration under the NAE (refresh the tree view if required to see a newly added LONWORKS Integration) and choose Field Device from the Insert menu. Assisted Definition using Auto Discovery is the easiest way to add a new thermostat online; however, this step requires that the new thermostat is connected and ready to communicate. Refer to the LONWORKS Network Integration with NAE Technical Bulletin (LIT-20668) for instructions on how to add a LONWORKS device. LONWORKS Thermostat Mapping Preparation Before mapping a TEC22x6-2 Thermostat into a Network Automation Engine (NAE):. Decide which point objects within the thermostat you need to map. Only map the point objects that you need to view on a regular basis, because excessive mapping lowers system performance. Suggested point objects for mapping include: Room Temp, System Mode, Fan Status, Occupied Heat Setpoint, Occupied Cool Setpoint, Unoccupied Heat Setpoint, and Unoccupied Cool Setpoint. In addition, alarm points may be mapped if they are used, and other point objects may be mapped if required. Use the Engineering view to examine infrequently used point objects. 2. Verify that a LONWORKS Integration is defined in the NAE. The commissioned thermostat is mapped as a LONWORKS device under a LONWORKS Integration. Refer to the LONWORKS Network Integration with NAE Technical Bulletin (LIT-20668) for instructions on how to define a LONWORKS network Integration. At this point, you can map the thermostat and the required point objects inside the thermostat. 2
