Legacy VAV1xx controllers identify themselves to their N2 supervisor as a VAV device type. The FX-PCV and FX-PCG support identifying themselves to its N2 supervisor as a VAV device type, which eliminates the need to change this in the N2 supervisor's configuration. To configure this capability, use the N2 Mapping feature of CCT to set the FX-PCV or FX-PCG controller's device type to VAV.

Controller's device type to VAV

No utilities are available to automatically recreate the N2 Mapping Table, so you must manually recreate it using CCT.
