Honeywell PCB DBM01A Ferroli Domiproject C 24
The Honeywell DBM01A PCB for the Ferroli Domiproject C 24 boiler is a device that controls the ignition, burner modulation, pump, and system safety features. When this part fails, the boiler may not start, become locked, or exhibit erratic behavior. It is installed in models such as the Domiproject C24, Domiproject F24, C32M, and F2, among other boilers in the Domiproject and Tempra ranges. It should be replaced when these fault symptoms occur.

How to check if ref. I39819530 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 I39819530. 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 I39819530 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 displays a fault code that does not clear when reset.
Cause: The PCB is responsible for the diagnosis; if there is a fault in its circuit, the error persists even if the indicated component is in good condition.
Note the exact code and first rule out the component that indicates that fault before replacing the entire PCB.
- 02
The boiler ignites, tries to operate, and stops without the control being able to do anything.
Cause: This PCB controls the ignition, modulation, and safety cut-off; an internal fault can interrupt the sequence.
Perform a complete cycle and observe at which step it stops; this helps to determine if the fault is in the PCB or in the component to which it sends the command.
- 03
The room thermostat is not communicating with the boiler.
Cause: The communication between the control and the PCB is carried out through the port of this board; if it fails, the demand is not received.
Check the connection of the control bus and, if the boiler allows it, test the direct manual mode to identify where the fault is.
- 04
A burnt smell or dark marks are detected when opening the boiler.
Cause: A damaged component on the PCB can burn out and affect the entire control unit.
Visually inspect the PCB before installing the new one; if the smell comes from another location (wiring, motor), the problem is not here.
Fault codes for Ferroli that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F50 | Anomaly in the control board. | A problem has been detected in the boiler's control board, which may cause faults in its operation. If the boiler does not respond correctly to commands or exhibits erratic behavior, it is possible that the PCB is faulty. |
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.
