• UPC3 - Mega-Tec 1.2.0

Bard part number 8301-076-002B is a UPC3 MEGA-TEC PLC control board assembly used on Bard MEGA-TEC wall-mount air conditioner platforms to manage unit staging and core operating logic. This OEM programmable controller is designed to restore correct factory control functions when a damaged or failed PLC board causes faults, lockouts, or erratic operation, and it is commonly referenced in MEGA-TEC control panel parts breakdowns as the UPC3 board. Because the trailing letter indicates the software revision level, confirm the required revision for your site and plan to update software across all related PLC devices (units and controllers) when replacing a board to keep the system communicating and operating as intended.
