Technical Bulletin: FCU Control Modules, Windows® XP and Windows ® 7
BTU’s older furnaces (from 1988 – 2002) utilized an FCU control module to communicate from the computer to the furnace. This technology was release more than 2 decades ago as the main communications network for all our furnaces. These units, along with computers operating on Windows® XP and Windows® 7, are no longer available and will need to be replaced by our newer Intellimax 2® control unit and a computer running Windows® 10.
