- UPC3 C2 - Mega-Tec 4.0.1
Bard part number 8301-112-002BBX is an OEM HVAC controller/control board used in Bard wall-mount and packaged systems that utilize the UPC3 C2 control platform, commonly referenced with Mega-Tec 4.0.1. This board is the central control for unit operation, coordinating calls for cooling and heating, managing safety and operating logic, and supporting proper sequencing so the equipment runs as designed. When troubleshooting nuisance lockouts, communication or control faults, or no-operation conditions tied to the unit controller, replacing with the correct Bard OEM 8301-112-002BBX helps restore reliable performance and factory-intended compatibility. Confirm the full unit model and serial number and match the board revision before ordering to ensure proper fit and programming requirements.
