558J units for installation in the United States contain use of Bryant's 2-speed indoor fan control system. This
complies with the U.S. Department of Energy (DOE) efficiency standard of 2018.
558J units for installation outside the United States may or may not contain Bryant's 2-speed indoor fan control
system as they are not required to comply with the U.S. Department of Energy (DOE) 2018 mandatory efficiency
standard.
558J*08N, 09N, 12N units for installation inside or outside the United States do not contain use of Bryant's 2-
speed indoor fan motor control system as they comply with the U.S. Department of Energy (DOE) 2018
mandatory efficiency standard without their use.
For specific details on operation of the Bryant 2-speed indoor fan system, refer to the Variable Frequency Drive
(VFD) Factory-Installed Option 2-Speed Motor Control Installation, Setup, and Troubleshooting manual.
