Honeywell PCB CS0147C-LS For Hermann Supermicra Ecoplus 24 SE
The Honeywell CS0147C-LS PCB is installed in the Hermann Supermicra Ecoplus 24 SE boilers and in models from the Thema F24 NOX range. Its function is to control the ignition, the modulation of the burner, the pump, and the safety features of the boiler. If it fails, you may notice that the boiler does not start, locks out, or exhibits erratic behavior. It is advisable to replace it when you experience these symptoms to restore the operation of your heating system.

How to check if ref. H052003714 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 H052003714. 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 H052003714 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 respond to anything: no indicators, no display, no attempt to ignite.
Cause: If the electronic management assembly fails, the boiler loses control and does not respond to any commands.
Before replacing it, check the visible fuse on the PCB and that it is receiving electrical power; many 'dead PCBs' are just a blown fuse.
- 02
The boiler ignites some days and not others, without a clear pattern.
Cause: An intermittent fault in the control electronics can cause the damaged contact or component to work sometimes and not at other times.
Check for any moisture or corrosion in the area of the PCB, especially if the boiler is located in a damp place.
- 03
The panel displays a fault code that does not match any known component of the installation, such as the sensor or the pressure switch.
Cause: If the fault is in the electronic management, the code points to the control set instead of an external, checkable element.
Cross-check the code with the Hermann manual for this model before deciding that the PCB is the cause.
- 04
The remote control or the programmer clock cannot communicate with the boiler.
Cause: These elements depend on the control electronics receiving and processing the signal correctly; if it fails, the boiler 'does not listen' even if the control is functioning properly.
Try resetting the remote and check its battery before assuming that the problem is with the boiler.
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.
