ACCA Announces ANSI Review Period for Two Standards
ARLINGTON, Va. — The ACCA Educational Institute (ACCA-EI) Standards Task Team (STT) announced the third public review of BSR/ACCA 15 OBD - 201x "On Board Diagnostic Codes for HVACR Equipment," and the second public review of BSR/ACCA 4 QM – 201x "Maintenance of Residential HVAC Systems."
The 45-day public review period of the On Board Diagnostic (OBD) Standard started on Aug. 24 and will close on Oct. 8. The OBD Standard details the naming schema for designating fault and performance codes for HVACR equipment. As defined and used in this proposed standard, the naming schema standardizes fault and performance codes based on location (with a modifier), mode of operation, process, operating parameter, and performance descriptor. The schema accommodates operating faults and/or performance characteristics that are commonly identified by today’s equipment diagnostic capabilities, and that may need to be identified as enhanced sensors and controls are applied to future HVACR offerings. Additionally, this standard provides for the incorporation of proprietary, manufacturer-specific information that individual manufacturers may choose to make available to field practitioners.
