Legacy AHU controllers have a device type of AHU. The FAC3613 or CGM09090 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 FAC3613 or CGM09090 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.
