How to check if it is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Look for the code 8/050151H printed on the PCB. Our units also show 97/03/09 and, depending on the unit, P2R and 9720 or 9718.
- Compara la letra final: 8/050151H no es 8/050151G, una variante que para la Themis 8/20.
- Check the relay and the fuse: relay with a 24 V DC coil (RYA30024 or AZ 696-1A-24DE) and a 80 mA T fuse.
- No la confundas con otros códigos que para las Themis (05712600, SD57126) ni con la S10470, de otra serie.

- THEMIS 23 — compatibilidad citada; pendiente de contraste con revisión concreta. Consulta 24/10/2026 · 1 proveedor; pendiente de confirmar: Themis 23. Declaración comercial para su ficha «Placa Electrónica Saunier Duval (8/050151H)», no certificación de la unidad. Confirmar referencia OEM, revisión, configuración y variante de equipo antes de usarla.
- Estos síntomas salen de la ficha de de la SD57126, no de la 8/050151H. No son un diagnóstico: que un técnico confirme la avería antes de cambiar la placa.
- No confundir: 8/050151G — Placa Saunier Duval que lista para la Themis 8/20, con identificador 100487/GBX — Cambia la letra final (G, no H). Confirmación registrada: la 8/050151H para la Themis 8/20.
- No confundir: 05712600 — Circuito impreso Saunier Duval que Designación registrada: la Themis 23 posterior a 1993 y la Themis 19V — sin confirmación adicional lo une a 8/050151H: no lo damos por equivalente.
- No confundir: SD57126 — Placa Themis reacondicionada que para Themis 23 y 8/20 después CE (y AS 23 y AS 14) — La ficha no cita 8/050151H ni dice que sea equivalente: no la damos por tal.

- Do not confuse: S10470 — Saunier Duval PCB (ref. 288.66.0004) for Thematek C24EO BT, Themafast 25E, Isofast and Themafast F 30 E H — Another series of PCB; it is not mentioned for Themis.
- 100487/I solo lo cita. Ningún despiece oficial abierto une 8/050151H con una referencia Saunier Duval; 05712600 y SD57126 aparecen para las Themis, pero sin confirmación adicional las une a 8/050151H. Compara siempre el código serigrafiado en tu placa.
