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 board or 52: Electronic board anomaly S may appear. It is compatible with several Beretta boilers, including Exclusive Mix 26 CSI, 30 CSI, 32 CSI, and 30 RSI, among others. It is recommended to replace it upon detecting issues in its operation.

How to check if the part R10029772 is the one for your boiler.
What determines it is not the boiler model, but the reference printed on the part you already have installed.
- 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.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the PCB R10029772 resolves.
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.
Fault codes for Beretta that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 51 | PCB (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. |
| 52 | PCB anomaly S | Variant 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. |
| 53 | EEPROM R&W Anomaly | Read/write error in the PCB EEPROM (service parameters). Try reprogramming the model parameters; if it doesn't save or reappears, the PCB memory is damaged and must be replaced. |
| 54 | Parameter setting error | Incorrect 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. |
| 55 | Parameter setting error S | Same as 54 but in "S" variant; service parameters of the PCB not valid. Reprogram model parameters; if recording fails, replace PCB. |
| 59 | PCB (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.
