Legacy VMA14xx controllers identified themselves to their N2 supervisor as a VMA device type. The FX-PCV1832 does not support identifying itself to its N2 supervisor as a VMA device type. As a result, you must use the CCT's N2 Mapping interface to set the FX-PCV1832 controller's device type to VND and reconfigure the N2 supervisor so that the FX-PCV controller is mapped as a VND device.

Additionally, the CCT System Selection Wizard for the Single Duct VAV Box (VAV-SD) application automatically defines the FX-PCV1832 controller's N2 point mapping table to resemble the VMA14xx controller's N2 point map. Doing so eliminates the need to change the N2 supervisor's point mapping configuration. All other VAV box control applications (for example, dual duct applications) require you to use the CCT N2 Mapping interface to manually create the N2 point mapping table.
