Beretta Exclusive MIX 26 CSI PCB Ref. R10029772

If your boiler does not start or behaves erratically, the Beretta Exclusive MIX 26 CSI PCB Ref. R10029772 may be the solution. This component, manufactured by Finder and with reference R10029772, controls the ignition, burner modulation, pump, and safety features of the boiler. When it fails, errors such as 51: Electronic card or 52: Anomaly of the electronic board S may appear. It is compatible with several Beretta boilers, including Exclusive Mix 26 CSI, 30 CSI, 32 CSI, and 30 RSI, among others. A technician must confirm through diagnosis whether it needs to be replaced upon detecting issues in its operation.

Guide

How to check if the part R10029772 is the one 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 R10029772. If it is not visible, do not identify the part from 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.
Diagnosis and fault codes

Symptoms that require diagnosis on the PCB R10029772

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 boiler ignites for hot water, but the heating pump does not start.

    Cause: The relay on the PCB that powers the pump is not closing the contact, although the rest of the board is functioning.

    Listen for the click of the relay when requesting heating; if you don't hear it, check the wiring and the capacitor of the pump.

  • 02

    The boiler does not ignite in any mode and the clicking sound of the gas valve is not heard when trying to start.

    Cause: The relay that controls the gas valve may not switch, preventing the opening from the source.

    Check the continuity of the gas valve coil with a multimeter before assuming that the fault is in the PCB.

  • 03

    The lock code appears and disappears on its own, without a clear pattern, especially when the boiler has been running for a while.

    Cause: The relay block heats up with use and some PCBs show intermittent faults that are corrected when they cool down.

    If the fault only appears with the boiler hot and resets well when cold, it points more to the PCB than to an external component.

  • 04

    The boiler heats the water well but not the heating, or vice versa: one of the two circuits is not responding.

    Cause: Each circuit depends on a different relay on the PCB, so one can fail without affecting the other.

    Before changing the PCB, confirm that the room thermostat is calling for heat correctly and that the three-way valve is not blocked.

Beretta fault codes that require diagnosis

CodeFaultTechnical checks
51PCB (control board)General fault of the PCB AB01B (R10029772): loss of 5 V, internal corruption, or component fault. Check 230 V/5 V power supply, CN connectors, and continuity; if it persists, replace and parameterize the PCB.
52PCB anomaly SVariant of fault in the PCB (self-test/status S) indicating management failure in the PCB. Check voltages and grounds, bus between PCB and panel, and test with reference PCB.
53EEPROM R&W AnomalyThis symptom may be related to the part, but it does not confirm that it is faulty. A technician must check the equipment and its inspection according to the manual before deciding on a repair or replacement.
54Parameter setting errorIncorrect parameters or unparameterized after replacing the PCB. Load the exact model configuration from the technical menu; if it does not accept or is lost, probable memory fault in the board.
55Parameter setting error SSame as 54 but in "S" variant; service parameters of the PCB not valid. Reprogram model parameters; if recording fails, replace PCB.
59PCB (control board)Specific alarm from the control board. Check 5 V, board-display communications, and relays/tracks; if everything is correct, the solution is to replace and parameterize the R10029772 PCB.

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.
