The FP AHU Discover Wizard should be run only after a WEMScontroller4 has been discovered and set up with the Auto Build option. For a guide on how to set up an FP AHU for the first time, see the FP AHU First-time Setup guide.
If a WEMScontroller4 has already been configured, the FP AHU Discover Wizard can be used to add an FP AHU to the Floorplan.
For a guide on the wizard, see Run The FP AHU Discover Wizard.
