ACCA Announces 60-day Review of On Board Diagnostic Standard

Standard details the naming schema for designating fault and performance codes for heating, ventilation, air-conditioning and refrigeration (HVACR) equipment.

ARLINGTON, Va.— The Air Conditioning Contractors of America Educational Institute (ACCA-EI) Standards Task Team (STT) today announced the second public review of BSR/ACCA 15 OBD - 201x (On Board Diagnostic Codes for HVACR Equipment). The 60-day public review period begins March 16, 2018 and closes on May 15, 2018.

The On Board Diagnostic Standard details the naming schema for designating fault and performance codes for heating, ventilation, air-conditioning and refrigeration 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.

A copy of the proposed Standard can be downloaded for free at www.acca.org/ansi. Comments on this public review must be submitted by May 15, 2018 (5:00 P.M. EDT) using the ACCA Public Response Form available at www.acca.org/ansi/.
