Legacy AHU controllers identify themselves to their N2 supervisor as an AHU device type. The FX-PCA3611 supports identifying itself to its N2 supervisor as an AHU 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 to set the FX-PCA controller's device type to AHU.
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.
