PCB Hermann Renova Micra Condens 26 Ref. H052005326
The PCB (control board) Hermann Renova Micra Condens 26 is crucial for managing ignition, burner modulation, pump, and safety systems of the boiler. When it malfunctions, the boiler may fail to start, become locked, or operate erratically, potentially displaying faults such as F.61, F.62, F.63, F.64, or F.65. This part is compatible with models Micra Condens 26, Micra Condensing 26, Micra Condensing 26 SB, Micra 2, and Renova Habitat, among others. It is recommended to replace it in case of recurring faults or abnormal behavior in the boiler.

How to check if ref. H052005326 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 H052005326. 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 H052005326 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 display shows a communication error with the remote control or blinks randomly.
Cause: The PCB manages communication; an internal fault makes it unstable.
With the boiler turned off, disconnect and reconnect the control and make sure that the bus wiring is properly secured.
- 02
There is no response at all: no indicators, no starting noise, nothing.
Cause: Without the PCB giving the initial command, no component of the boiler is activated.
Check the fuse on the PCB and ensure that the boiler is receiving 230V from the mains before replacing it.
- 03
The factory settings have changed or have been lost on their own.
Cause: The PCB stores the configuration in its memory; a fault can cause it to reset or become corrupted.
Note which parameters have changed and if it coincided with a power outage, as this helps to determine if it is the PCB or a simple reset.
- 04
The boiler ignites, attempts to light the flame, and shuts off after a few seconds without further explanation.
Cause: The PCB interrupts the cycle if it does not receive the expected confirmation from another component within the specified time.
Check at which exact step it cuts off (ventilation, ignition, flame) to determine if the problem is in the PCB or in the component that is waiting for a response.
Fault codes Hermann that this part solves
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F.61 | Error: gas valve control | The PCB controls the coils of the valve; if the driver/output on the board fails, a control error is detected. Check voltage and continuity to the valve and, if correct, replace the PCB. |
| F.62 | Error: gas valve disconnection controller | The control circuit of the valve is on the PCB; a fault in that stage can leave the valve powered or cut off late. Check the electrical closure after demand, and if the wiring/valve are OK, replace the PCB. |
| F.63 | Error: EEPROM | The EEPROM memory is integrated into the PCB; data corruption or memory IC failure triggers this code. Verify with parameter reset (d.96) and, if it reappears, replace the PCB. |
| F.64 | Fault: PCB / sensor / analog to digital transformer | The A/D converter and its inputs (NTC) reside on the PCB; if that electronics fail, F.64 is registered. Check NTC/wiring; if they are correct, the cause is the PCB. |
| F.65 | Error: electronics temperature too high | The thermal sensor on the PCB detects overheating or the circuit faults. Check for external causes (heat/ventilation) and, if it persists without reason, replace the PCB. |
| F.67 | Incorrect value returned by ASIC (flame signal) | The ASIC of the PCB interprets the ionisation; if the ASIC/flame channel fails, F.67 appears. Check for the presence of flame and ground; if they are correct, the PCB is the cause. |
| F.70 | Invalid product code (DSN) | The DSN/coding resides in the PCB; if the display and PCB are changed without readjusting the DSN, F.70 will trigger. Verify and reprogram the DSN according to the manual; if it is not corrected, recode or replace the PCB. |
| Connection | No communication between the main PCB and the user interface | The PCB manages communication with the UI; a bus/driver fault on the board triggers this alarm. Check connectors X32/X35 and 24 V; if the wiring is fine, replace the PCB. |
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.
