The Bard 8602-056-0007BX Programmed Econ Module is an OEM control module used in Bard economizer-equipped HVAC systems to manage the economizer sequence and help the unit bring in outdoor air when conditions allow for efficient operation. Because this is a programmed module, it is intended to match specific Bard equipment configurations and economizer setups, so confirming compatibility by model and serial number before ordering is important. Installing the correct OEM module helps restore proper economizer control, reduces nuisance economizer issues, and supports reliable unit operation in commercial wall-mount and packaged applications.
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
