De Dietrich Storage parameter unit S100650

The De Dietrich S100650 storage parameter unit is an electronic control board designed to store key boiler parameters, including temperature settings, operating modes, and sensor signals. It ensures stable boiler control even during power outages by preserving these settings. This board is compatible with a range of De Dietrich boiler models, including C 230 Eco, M 40-S, C 310 / 610 Eco, GT 430, C 210 Eco, MCR…MI, 200/1S, C 230-..

Parts of this type are selected by matching the specific boiler model and the board's reference number. Before ordering, verify the boiler's model and compare the existing board's part number with the replacement. Installation typically involves disconnecting power, removing the old board, and connecting the new one according to the wiring diagram. Ensure the board is securely mounted and all connectors are properly seated.

When this type of board fails, the boiler may lose saved settings, revert to default parameters, or exhibit erratic behavior such as incorrect temperature control or failure to respond to sensor inputs. In some cases, the boiler may not start or may shut down unexpectedly. Check the board for visible damage, loose connections, or signs of overheating, and verify that stored parameters are retained after a power cycle.
