- UPC3 - Fusion-Tec WR 3.1.1
Bard part number 8301-068-004A is an OEM UPC3 control module used on Bard wall-mount air conditioner platforms such as Fusion-Tec and other PLC-controlled units. This board is responsible for core unit logic, coordinating inputs and safeties and managing system functions so the equipment can operate and communicate correctly. Bard documentation notes that UPC3 replacements may carry a letter at the end of the part number to indicate the software revision, and Bard recommends updating software across all onsite PLCs (unit controllers and any associated controllers) when a PLC module is replaced, so confirming the correct revision and compatibility to your unit model and wiring diagram before ordering helps ensure a smooth swap and proper startup.
