Legacy UNT controllers identify themselves to their N2 supervisor as a UNT device type. The FX-PCG supports identifying itself to its N2 supervisor as a UNT device type, which eliminates the need to change this setting in the N2 supervisor's configuration. To configure this capability, use the N2 Mapping feature of CCT as shown in Figure 1.
Additionally, the CCT System Selection Wizard for the Mixed Air Single Duct Air Handling Unit (MASD) application includes an option to automatically define the N2 mapping table to minimize N2 supervisor reconfiguration. All other applications require you to manually create the N2 Mapping Table.
