Fault Detection and Diagnostics (FDD) from the Luxaire® brand of Johnson Controls aims to help building professionals maximize rooftop unit performance. Available exclusively with Simplicity® Smart Equipment (SE) Controls, FDD technology monitors refrigeration circuit temperatures and pressures, economizer operation, and outdoor humidity and temperatures. If issues arise, FDD provides access to detailed alerts, speeding up response to situations before they lead to possible equipment performance issues, said company officials. Detailed alerts are accessible anytime from a smartphone or other remote device. With the Simplicity SE Controls Mobile Access Portal (MAP) gateway, alerts can be viewed on a web browser.

With FDD, Johnson Controls claims that users can configure, commission, and troubleshoot packaged units faster; engineers can confidently confirm specifications; and building owners can cut energy and service costs.
