Placa de alimentación «88055604» de De Dietrich DELTA T

This is a De Dietrich electronic control board (PCB) designated as a DELTA T supply board. In modern wall-hung boilers, such boards perform the same role as a standalone burner control: they run the ignition sequence, enforce safety times (pre-purge, ignition, flame proving, lockout), read pressure switches and the flame signal, and drive the ignition transformer, gas valve, and fan. A board of this type contains the logic for modulation and communicates with temperature sensors, the circulation pump, and the three-way valve. Replacement selection is by boiler model series and, if applicable, the original board’s part number. Electronic control boards are nearly always matched to a specific boiler design; a board from a different series is not interchangeable, even within the same brand. No additional dimensions, voltage ratings, or compatibility information is available for this article beyond its manufacturer codes 88055604 and 336.568.018.
