Honeywell PCB S4862V320B - Immergas Victrix Tera 24/28/32
The Honeywell S4862V320B PCB is the control component that regulates the ignition, burner modulation, pump, and safety features of the boiler. If this part fails, the boiler may not start, lock out, or exhibit erratic operation, displaying fault code 20: Flame lockout. This model is compatible with Immergas Victrix Tera 24, 28, and 32 boilers, among others. It is advisable to replace it when these symptoms or faults in operation are detected.

How to check if the reference 046755 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 046755. 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 046755 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 LCD screen does not turn on or display anything, and the boiler does not respond to the controls.
Cause: If the PCB fails, the display will not be visible and the boiler cannot be controlled.
Check if there is power to the boiler; if there is voltage and it does not respond, the fault is with the PCB.
- 02
The boiler does not respond to the panel controls even though it seems to have power.
Cause: A fault in the microprocessor of the PCB prevents the commands from reaching the burner.
Turn off and on the boiler from the main switch; if it still does not respond, you will rule out a simple electronic hang-up before replacing the PCB.
- 03
The boiler locks or turns off by itself without any clear code displayed on the screen.
Cause: If the display is affected, the fault codes it should show are not visible or are unreliable.
Note any blinking or symbol you can distinguish before it turns off, and check if the lock coincides with the ignition or with the demand for domestic hot water.
Fault codes from Immergas that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 20 | Flame lockout | The boiler has detected a problem with the flame. This may be caused by a fault in the gas supply or in the ignition. If the boiler does not ignite, check the PCB, as it could be the culprit. |
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.
