ACV Printed circuit display A1002098

The ACV A1002098 is a printed circuit display for ACV boilers, identified by hardware revision DSP49G2243 and firmware version C256K. It shows operating parameters, temperature readings, fault codes, and system status on the control panel. This display is compatible with ACV HeatMaster 100 TC, Prestige Box Mono 75, and Smart Line SL 50 models. It features expanded memory capacity and is designed for direct swap installation.

When selecting a replacement display of this type, verify that the firmware version and hardware revision match the original part, as different versions may not be electrically or functionally interchangeable. Ensure the part number on the existing display matches the available unit before fitting. The display connects to the main control board via a ribbon cable or plug connector; no modifications to the wiring harness or control board should be necessary if the part is a direct swap.

If the display fails, the boiler may continue to operate but without readable status information, making fault diagnosis difficult. Common failure modes include blank screens, garbled characters, or unresponsive buttons. Check the ribbon cable connection and the display's power supply before replacing the unit.
