Honeywell PCB for Hermann MicraCom Condens 24 Ref. CS01770-LS
The control PCB from Honeywell for the Hermann MicraCom Condens 24 boiler manages the ignition, burner modulation, pump, and system safety features. When it fails, the boiler may not start, may lock out, or may exhibit erratic behavior. This part is compatible with several models, including the Plus 23 E, Inox 30 SE, and others from the Micra range. It is recommended to replace it if you experience any of these operational issues.

How to check if it 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 —. 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 and faults that the PCB (control board) 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 boiler does not turn on at all, not even a LED, as if it has no power.
Cause: The PCB distributes power to the entire circuit, and a fault at its input leaves it without power.
Check that power is reaching the boiler before replacing the PCB.
- 02
An error code appears that does not correspond to any actual fault related to water, gas, or pressure.
Cause: The electronic control misinterprets an input signal even though the sensor is functioning properly.
Note the code and consult the fault manual before attributing the fault to the PCB.
- 03
The boiler makes several consecutive ignition attempts, and none are successful.
Cause: The electronic control manages the ignition sequence and interrupts the process if its logic detects an anomaly.
Discard correct gas and water pressure before holding the PCB responsible.
- 04
The remote control or the thermostat are not responding, although the boiler operates in manual mode.
Cause: There is a communication failure between the PCB and the remote accessory, not the local control of the boiler.
Test the boiler from the local panel before replacing the PCB: if it responds there, first check the communication wiring.
- 05
The boiler stops by itself and needs to be reset, without any visible cause in the installation.
Cause: The electronic control cuts off the supply as a safety measure in response to an internal instability it detects.
Record when the cut occurs before deciding that the PCB is the cause.
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.
