Bard 8602-056-0004BX - Programmed Econ Module

Bard part number 8602-056-0004BX is a programmed economizer control module intended for service replacement on compatible Bard wall mount and packaged HVAC systems equipped with an economizer. This OEM control module helps manage outside air operation so the economizer opens and closes when commanded, supporting proper ventilation and economizer cooling sequences. If your unit has economizer faults, erratic damper operation, or will not enable free cooling when conditions are right, replacing the failed control with the correct programmed module can restore reliable operation. Because economizer modules are application specific, confirm the exact part number and unit model and serial compatibility before ordering to ensure proper plug-in fit and correct control logic for your Bard equipment.

What does the "BX" suffix mean?

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.
