De Dietrich 200005008 board UC K3

The De Dietrich 200005008 board UC K3 is an electronic control board (PCB) intended for use in a modern wall-hung boiler. It carries the catalogue article 336.568.010 and the manufacturer codes 200005008 and 336.568.010. The board itself is a branded De Dietrich spare part and belongs to the category of electronic control boards. Boards of this type perform the same role as a conventional burner control (flame safeguard) but are integrated into a single printed circuit assembly. They orchestrate the entire ignition and safety sequence: starting with a heat demand, they initiate pre‑purge, check the air pressure switch, drive the ignition transformer, admit fuel, prove flame via an ionisation electrode, and enter lockout if flame is not established within the safety time. They also manage modulation by adjusting fan speed and gas valve position based on temperature sensor inputs. When replacing a control board of this class, it is critical to match the exact series and type designation, supply voltage, safety and pre‑purge times, and flame detection method. Even within the same brand, a board from a different series is normally not interchangeable; a mismatched safety time creates a genuine safety hazard. The board is specific to the boiler model it was designed for, and no universal substitute exists. Always confirm the original part number before ordering.
