Standard 207-2025 -- Laboratory Method of Test of Fault Detection and Diagnosis for Air Economizers
Full Description ANSI/ASHRAE Standard 207 provides methods for laboratory testing of fault detection and diagnosis (FDD) systems to determine whether they perform as specified. The standard applies to FDD systems intended to detect or diagnose faults that affect the performance of air economizers of air-conditioning equipment and defines laboratory tests for faults in four categories of economizer function: sensor communication, actuator communication, damper and actuator responsiveness, and damper position. The standard only applies to those FDD systems designed to detect or diagnose faults by evaluating instantaneous or short-term conditions and parameters. This 2025 edition of Standard 207 updates normative references. |
