Bard part number 8301-099-001BX is an OEM programmed controller board supplied boxed for Bard wall-mounted HVAC applications using UPC3-based control platforms. This board is the unit’s primary logic and interface module, coordinating key operating functions and enabling service diagnostics and communication features used during troubleshooting and setup. If you are replacing a failed control or addressing recurring fault conditions, using the correct pre-programmed Bard board helps ensure proper sequences, protections, and compatibility with the rest of the unit wiring and sensors. Confirm the exact part number and required program level for your specific model and serial number before ordering, since similar UPC3 boards may look alike but are not interchangeable.
