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.
- Look for the Honeywell module S4962V3182V01 and the designation ABM03C on the PCB; compare the software (86656-006 or 86656-010) and the silkscreen 50075186-004.
- Check the complete model, gas type, and series on the rating plate of your Ferroli.
- Don't confuse them: 39845845 (ABM03E) and 39845841 (ABM03A) are kits from other editions; 39845850 and 39846490 are the mask, not the central kit.
- if they match, call us at 911 17 77 77 with the model of your boiler.
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 shows A61, A63, F64, A65 or F66.
Cause: Internal anomaly of the control board ABM03 according to the manual of the PRO S 27C: check the ground before replacing it.
- 02
The boiler shows A62.
Cause: Lack of communication between the control board and the gas valve according to the manual: check connection and valve.
- 03
In the Pro S 27C, the boiler shows A61, A63, F64, A65, or F66.
Cause: Internal anomaly of the ABM03 control board. It could be the PCB, but the code alone does not prove it.
Check the ground of the boiler before replacing the PCB. If the fault persists, compare the label of your PCB with this one (S4962V3182V01, ABM03C) and consult us.
- 04
In the Pro S 27C, the boiler shows A62.
Cause: Lack of communication between the control board and the gas valve. The fault may be in the PCB or in the valve.
Check the connection between the PCB and the gas valve, as well as the condition of the valve, before replacing the PCB.
Honeywell fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| A61 | In the Pro S 27C: internal anomaly of the control board ABM03. | Check the boiler's earth connection before replacing the PCB. It does not independently verify that the PCB is faulty. |
| A62 | In the Pro S 27C: communication failure between the control board and the gas valve. | Check the connection of the PCB with the gas valve and the valve itself. It could be the PCB or the valve. |
| A63 | In the Pro S 27C: internal anomaly of the control board ABM03. | Check the boiler's earth connection before replacing the PCB. It does not independently verify that the PCB is faulty. |
| F64 | In the Pro S 27C: internal anomaly of the control board ABM03. | Check the boiler's earth connection before replacing the PCB. It does not independently verify that the PCB is faulty. |
| A65 | In the Pro S 27C: internal anomaly of the control board ABM03. | Check the boiler's earth connection before replacing the PCB. It does not independently verify that the PCB is faulty. |
| F66 | In the Pro S 27C: internal anomaly of the control board ABM03. | Check the boiler's earth connection before replacing the PCB. It does not independently verify 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.

Frequently asked questions about the PCB (control board)
Where is the code for this PCB and what does each one mean?
The board marks the Honeywell module S4962V3182V01 and the designation ABM03C, as well as the software (86656-006 or 86656-010) and the silkscreen 50075186-004. In Ferroli's lists, "KIT CENTRAL. ABM03C" is 39845843, with 38326223 in parentheses. The code S4962V3182 (without V01) of the ABM03 boards from Ferroli; three refer to it as Honeywell and link it to ABM03E (39845845), not to ABM03C. Without additional confirmation, it does not explain the software or the silkscreens.
Is it compatible with my Ferroli Bluehelix PRO S 27C-E, PRO 25C or TECH C-E?
The compatibility of this variant is pending confirmation. Registered: for the PRO S 27C-E (also PRO-S 27 C) and the PRO 25C model 2. The Ferroli lists from 2016 give the PRO S 27C-E and the TECH 25C-E the same central kit B01 ABM03C 39845843; the TECH 25C-E and the 35C-E are yet to be confirmed. For the PRO 25C without model 2, the 2013 list includes 39845841 (ABM03A): compare the PCB.
What other boilers use the same kit ABM03C 39845843?
The compatibility of this variant is pending confirmation. To be confirmed: The official list 30K1280002 includes the Bluehelix TECH 18A-E, 25A-E, and 35A-E, and the Italian ones include them by family. For the Twist Pro 25C, check the code and an Italian one only includes the family; no official list. The official lists for the PRO 32C (2013) and the PRO S 32C-E (2019) have a different kit: 39845841 and 39845845. Another boiler? Send a photo of the label via Contact.
Is ABM03C the same as ABM03E or the codes 39845841 and 39845845?
In the Ferroli lists, there are different kits: 39845841 (ABM03A) for the PRO 25C and 32C from 2013, 39845843 (ABM03C) for the PRO S 27C-E and TECH from 2016, and 39845845 (ABM03E) for the PRO S 32C from 2019. They mix them up: they list them as alternatives or refer to 39845843 as ABM03 D; an Italian source claims that ABM03E replaces ABM03C and titles 39845843 as "replaced by FE39845844."
What fault codes of the boiler are related to this PCB?
The compatibility of this variant is pending confirmation. In the manual for the PRO S 27C (3541F263), A61, A63, F64, A65, and F66 indicate an internal anomaly of the ABM03 control board, while A62 indicates a communication failure with the gas valve. They do not independently prove that the PCB is faulty. The 3541F554 (2018) references ABM03C in errors and ABM03E in the diagram.
Who should install it?
A qualified technician: the PCB controls a gas boiler. Any questions about the model? Call 911 17 77 77 or send a photo of the label via Contact.
What is the reference of the spare part?
39845843 (38326223) is the ABM03C central kit that appears in the Ferroli BOM. It does not list it as an individual MPN for the standalone Honeywell PCB.
Which boilers is the ABM03C kit compatible with?
The compatibility of this variant is pending confirmation. BLUEHELIX PRO S 27C-E and BLUEHELIX TECH 25C/35C in the MET/GPL variants listed in the breakdowns from 2016. Confirm full model and series; previous catalogs show another version of the control board.
Are S4962V3182V01 and 86656-006 officially cross-referenced with ABM03C?
No public document from Honeywell or Ferroli confirming that combination was found; it registers a secondary commercial sheet assigning ABM03B/I39845845, so a substitution should not be inferred.
What do the codes A61 and A62 indicate?
In the BLUEHELIX PRO S 27C manual, A61 is associated with an internal control board anomaly and A62 with a lack of communication with the gas valve. The manual indicates to check connections and components; they do not diagnose this loose PCB by themselves.
