Honeywell PCB Baxi Roca Aequator A 24/24F
The Honeywell Baxi Roca Aequator A 24/24F PCB is a control component that manages the ignition, burner modulation, pump, and safety functions of the boiler. When it malfunctions, the boiler may fail to start, become locked out, or operate erratically. This board is compatible with the Aequator range, including the A 24/24F model, among others. A technician should assess the need for replacement through diagnosis when the boiler exhibits these malfunction symptoms.

How to check if it is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference —. If it is not visible, do not identify the part by 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 that require diagnosis on the PCB
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 won't turn on, there are no lights or display, it seems dead.
Cause: A fault in the control electronics prevents the unit from receiving power or starting up correctly.
Check the fuse on the PCB and make sure it is receiving mains power correctly.
- 02
The remote control or display shows a fault code that does not clear or change for no reason.
Cause: The PCB may be misinterpreting the signals from the sensors or activating protections due to an internal fault.
Note the exact code and consult it in the manual for your model before assuming it is the PCB.
- 03
The boiler ignites, runs for a few minutes, and then shuts off by itself repeatedly.
Cause: An incorrect reading on the inputs of the PCB can cause the burner to shut off for safety reasons without there being a real gas fault.
Before changing the PCB, rule out that the problem comes from a sensor or pressure switch connected to it.
- 04
The pump, the fan, or the gas valve do not start even though the boiler requests heat.
Cause: A burned relay or a damaged trace on the PCB can prevent the command from reaching the corresponding component.
With the boiler turned off, visually inspect the PCB for burnt, swollen, or dark-marked components.
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.
