Bard part number 8612-074BX is an OEM BrightStat CO2 expansion card used for demand controlled ventilation on compatible Bard wall mount and packaged systems. Installed in the BrightStat controller expansion slot, this module enables CO2 based control of ventilation so the unit can manage fresh air delivery based on room occupancy, with support for on off or 0 to 10V modulating strategies depending on the ventilation option and unit configuration. If you are troubleshooting inconsistent ventilation operation or replacing a failed CO2 control accessory, using the correct Bard OEM 8612-074BX card helps restore proper controller functionality and keeps your equipment operating to factory specifications.
