100% original, brand new Ideal Boiler parameter chip card. The item is immaculate, completely uninstalled, and remains safely housed in its original manufacturer white-labeled bag with factory scannable barcodes intact. This BCC (Boiler Chip Card) acts as the data profile key for the main electronic control board. When installing a replacement PCB, this card plugs directly into the designated interface slot to program the board with the exact factory configurations, output limits, and safe operating data required for a 24kW combination boiler frame.
