Guide

How to check if ref. 20218224 is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

  1. Find the reference printed on the installed part and check whether it matches the catalogue reference 20218224. If it is not visible, do not identify the part by its shape alone.
  2. Check the full boiler model on its data plate and look for it in the model associations on this page.
  3. Compare the connections and physical body with the original part before installation.
  4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.

The PCB controls the ignition, modulation, and safety features of the boiler. These are the typical symptoms and what to do:

Common symptoms and faults

  • 01

    The solar group's display does not show information or does not respond.

    Cause: There may be a problem with the power supply, the connections, or the interface; the symptom does not identify the faulty part on its own.

    Note the model of the solar group and the behavior of the display. Request technical verification according to the manual, without manipulating electrical connections.

These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.

Frequently asked questions

Frequently asked questions about the PCB 20218224

Are HelioSet GHS 8 and GHSD 8 gas boilers?
No. Saunier Duval identifies them as hydraulic groups for thermal solar systems. This screen should not be attributed to the control of a gas burner.
How do I confirm that this screen is suitable for my solar group?
Compare the complete reference and the review of the original PCB with this unit and with the equipment's breakdown. The designation HelioSet or a similar photograph is not sufficient to confirm compatibility.
Does a screen failure require changing this PCB?
Not necessarily. The power supply, connections, and interface must be checked through technical diagnosis before deciding on replacement.
