ACV printed circuit display 537D3020

This display module is a screen interface for an MCBA-type burner controller. It receives power and data through a ribbon cable or dedicated header from the control board. It is designed for ACV boilers, including the Compact Condens 35, Prestige 50 Solo MK2, and Heatmaster 70 TC. The module mounts in the front panel using screws or snap-in clips and has article number 129.253.003.

Displays of this type are selected by matching the manufacturer code and the exact control model; an incorrect display may not communicate, show garbled characters, or fail to indicate lockout codes. They connect to the control board via a ribbon cable or dedicated header and are mounted in the front panel with screws or snap-in clips. Before installation, disconnect the burner from the mains supply and inspect the ribbon cable for damage. Ensure the connector is oriented correctly, as reversed polarity can damage the display or the control board.

A failed or incompatible display may show garbled characters, fail to illuminate, or unable to communicate with the control board, leaving fault codes unreadable. The burner may operate but technicians and users cannot monitor system status or access diagnostic information. Check the ribbon cable for visible damage and ensure the connector is fully seated and correctly oriented.
