De Dietrich S101762 ny moduł regulacji parametrów przechowywania

This De Dietrich S101762 storage parameter unit is an electronic control board (PCB) that retains operating parameters for the boiler’s burner control. In modern wall-hung boilers, a storage parameter unit holds configuration data such as modulation curves, temperature setpoints, ignition and safety times, and system-specific settings. The main control board reads this data during startup and operation, ensuring the ignition sequence, flame proving, and modulation are matched to the appliance. The storage parameter unit communicates with the control board via a plug or wiring harness; it does not directly drive actuators or read sensors, but its data dictates how the control board operates the fan, gas valve, ignition transformer, and other components. Parts of this type are selected exclusively by the boiler model and the control board series they are designed for. Electronic control boards and their associated parameter units are rarely interchangeable across different models, even within the same brand. A mismatched storage parameter unit can cause incorrect safety times, wrong output settings, or a lockout fault. When replacing this unit, confirm that the part number and series match the original. The parameter unit may be shipped unprogrammed or with default values; if so, the boiler may need a configuration step using a service tool or parameter upload after installation. Always observe electrostatic discharge precautions when handling any PCB. If the boiler remains nonfunctional after replacement, verify that the control board reads the new unit and that no other board fault exists.
