De Dietrich 200007082 Diematic 3/III-PR relay board

The De Dietrich 200007082 Diematic 3/III-PR relay board is an electronic control board (PCB) for a heating system. Parts of this type manage the ignition and safety sequence: they read signals from sensors such as the room thermostat, pressure switches, and flame detectors, and drive the fan, gas valve, ignition transformer, and circulation pump. The board is specific to the control logic and wiring of the system it belongs to. Electronic control boards of this class are matched to the boiler model and are not interchangeable across different series, even within the same brand. A mismatch in safety times or supply voltage can create a safety hazard, not just a functional fault. When selecting a replacement, the exact series and type designation must match the original. The supply voltage, safety times, pre-purge times, and flame detection method (ionisation, UV, or IR) must be verified against the boiler specification. This specific article is identified by the name De Dietrich 200007082 Diematic 3/III-PR relay board and the manufacturer codes 200007082 and 336.568.013, with the catalogue article 336.568.013. No further technical data is available for this item beyond its designation as an electronic control board for a De Dietrich system.
