Honeywell Ignition Transformer AC1A114 - Hermann Micra Condens 26 / Master / Spazio / Thesi 26-32 / Saunier Duval Acquaplus 32
Honeywell ignition transformer, reference AC1A114, identified by the printed marking on the part. It operates at 50-60 Hz. It is installed in Hermann Micra Condens, Master, Spazio, and Thesi 26/32 boilers, as well as in the Saunier Duval Acquaplus Condensing 32. It is replaced when the burner ignition fails due to the absence of a spark. The store catalog listed a different reference (H052005087) that does not correspond to this part.

How to check if ref. H052005087 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 H052005087. 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 ignition transformer H052005087 resolves.
The ignition transformer generates the high voltage for the spark of the electrodes. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler does not ignite the burner even though gas is arriving normally.
Cause: The transformer has an open internal coil and does not generate the spark needed for the electrode.
With the boiler in ignition cycle, check if there is a visible spark at the electrode before replacing the transformer.
- 02
The spark appears intermittently, sometimes yes and sometimes no, without a clear pattern.
Cause: The connectors of the transformer or the electrode are oxidized and reduce the current reaching it without the part being broken.
Check that the connectors of the transformer and the high voltage cable are not oxidized or loose.
- 03
The ignition fault appears after a period of humidity or after cleaning the combustion chamber.
Cause: The condensation inherent to these boilers promotes that the high voltage is grounded before reaching the electrode.
Check the combustion chamber and the area around the electrode for moisture or accumulated condensation before replacing the transformer.
- 04
There is a spark at the electrode, but the burner does not ignite.
Cause: If there is a spark present, the transformer is likely functioning: the problem is in another part of the ignition circuit.
If you confirm a visible and constant spark, check the gas supply and the gas valve before replacing the transformer.
Fault codes for Renova that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 01 | Ignition fault: the burner does not ignite normally or the flame does not form/extinguishes unexpectedly (steady red LED, lockout after several attempts). | The ignition transformer generates the spark that ignites the burner; if it is faulty, no spark occurs and the boiler locks with Error 01. Check: with the boiler in demand, verify if there is a spark at the electrode and measure the high voltage output of the transformer; rule out the electrode, cable, connector, and gas supply first, as this same code can be caused by other components of the ignition group. |
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.
