Unical DUA B Btfs 28E Control PCB Ref. 00260145 03
When you open the tap or start the heating, the Unical DUA B Btfs 28E Control PCB Ref. 00260145 is responsible for managing the ignition, the modulation of the burner, and the safety features of the boiler. If this part fails, you will notice that the boiler does not start, gets locked, or exhibits erratic operation, potentially displaying fault codes such as "Main board damaged" or "REGOLAFACILE 19". It is compatible with models from the DAKON and DUA ranges, such as the DUA 24 CT and the BTFS 28, among others. It should be replaced when you experience these operational issues.

How to check if the ref. 00260145 03 is the part 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 00260145 03. 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 00260145 03 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 does not ignite, it does not respond to anything.
Cause: A fault in the power supply block of the PCB can cut off power to the entire control electronics.
First, check the main power supply of the boiler and the installation fuse before replacing the PCB.
- 02
The display shows a fault code without any visible fault in the boiler.
Cause: An aging component on the PCB can give an incorrect reading from a sensor without there being a real fault in it.
Reset the boiler and note if the fault code repeats before deciding that it is the PCB.
- 03
The remote control cannot program or modify anything in the boiler.
Cause: If the communication stage of the PCB fails, the control loses control over the boiler even if it is connected.
Check that the wiring of the control is properly connected and free of corrosion before replacing the PCB.
- 04
The boiler ignites the burner but shuts off after a few seconds repeatedly.
Cause: The PCB may not be processing the safety signals correctly and interrupts the cycle as a precaution.
Check that the safety sensors (pressure switch, flame sensor) are properly connected before blaming the PCB.
Fault codes Unical that this spare part solves
| Code | Fault | Diagnosis and solution |
|---|---|---|
| Main PCB damaged (LED 65° 60° 55° 50° 45° 40° 35°) | Main/modulation PCB damaged: the boiler is locked. | Fault in the modulation PCB (board 00260145‑03) due to component damage or power/firmware issues; verify by resetting the network, checking connections/harness and board voltages; if it persists, replace the PCB. |
| REGOLAFACILE 19 | Factory parameter alteration (lock). | Corruption/alteration of parameters in the modulation PCB; after reset, if it does not disappear, Unical itself indicates to replace the board (memory/EEPROM of the 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.
