software_title: "Haxall-based (Axon) fault auto-correction package for building HVAC\
  \ system (Haxall-based Fault Correction) v1.0"
acronym: "Haxall-based Fault Correction v1.0"
doi: "https://doi.org/10.11578/dc.20230628.4"
description: "\tHaxall-based Fault Correction is a set of fault auto-correction algorithms\
  \ implemented using the Axon language. These algorithms can automatically fix equipment\
  \ and control problems as they arise and improve the operation of building Heating,\
  \ Ventilation, and Air Conditioning (HVAC) systems. The coded auto-correction algorithms\
  \ include mitigation of rogue zones, ASHRAE Guideline 36 static pressure and supply\
  \ air reset, resolution of control hunting due to improper settings in a proportional-integral-derivative\
  \ controller, correction of biased temperature sensors, etc. FDD tools with enhanced\
  \ auto-correction capability can resolve control problems as they are detected,\
  \ increasing energy savings and emissions reductions while freeing up operational\
  \ staff expertise for the hardest facility problems."
