Honeywell PCB SMC0E01 For Edyco Boiler ED 21 EI / ED 21 I
The Honeywell SMC0E01 PCB is a control component used in the Edyco ED 21 EI and ED 21 I boilers. Its main function is to manage the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the boiler may not start, may lock out, or may exhibit erratic behavior. This board is also compatible with models from the Cointra range. A technician must confirm through diagnosis whether it needs to be replaced when these symptoms occur, as its malfunction can affect the performance of the boiler.

How to check if ref. 9158792 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 9158792. 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 that require diagnosis on the PCB 9158792
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 start after a power outage or voltage surge.
Cause: Power outages can damage components of the PCB, such as the transformer or the control circuit.
Check the fuse on the PCB and the circuit breaker of the installation before replacing it.
- 02
The boiler heats the heating system but does not produce hot water, or vice versa.
Cause: The PCB determines which circuit has priority; if the control circuit fails, it may stop activating one of the services.
Check that the fault is not with the three-way valve before inspecting the PCB.
- 03
The circulation pump does not start even though the boiler is requesting heat and everything else is functioning.
Cause: A damaged output relay on the PCB prevents the start command from reaching the pump.
Check if there is power at the pump connector when the boiler is calling for heat, before replacing the PCB.
- 04
The temperature settings or the operating mode reset themselves occasionally.
Cause: A power failure on the PCB causes it to lose the saved configuration.
Check if the issue coincides with power outages at home before considering the PCB as faulty.
- 05
The fan stays on continuously even though the boiler is not requesting heat.
Cause: If the relay that cuts off the fan output gets stuck on the PCB, the component does not receive the command to stop.
Disconnect the fan and check if it is still receiving power from the PCB before replacing it.
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.
