Guide

How to check if it is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

Please confirm: Look for the code 0020035375 and the designation PM-02 on the PCB; indicate that the reference is usually printed on the circuit or on a side sticker.
Check the rating plate of your boiler: the Saunier Duval Themacondens F24 is registered for this plate.
Compare the number and position of the relays and connectors: note that different versions have been manufactured under the same reference.
Compare with the 0020018478, the code provided for the Themafast Condens F 24 and F 30 and for the Thema Condens F 24 E: no documentation states whether it is the same PCB.
if they match, call us at 911 17 77 77 with the model of your boiler.

Diagnosis and fault codes

Symptoms that require diagnosis in the Saunier Duval.

Common symptoms and faults

01
The boiler does not ignite or respond to any commands from the front panel.
Cause: To confirm: it is associated with a fault of this PCB.
02
Erratic fault codes appear that change for no apparent reason.
Cause: To confirm: as a sign of damaged PCB; consult your model's manual to interpret the fault code.
03
Strange clicking sounds can be heard or there are stuck relays in the circuit.
Cause: To confirm: it is related to this PCB.
04
Burnt traces or visible oxidation on the PCB.
Cause: To confirm: as a sign of damaged PCB.
05
The boiler restarts by itself during the operating cycles.
Cause: To confirm: it is associated with a fault of this PCB.
06
The boiler does not ignite: the fault code F28 appears (ignition fault).
Cause: Failed ignition: it could be gas, ignition, electrode, or PCB.
Have a technician check it.
07
The boiler shuts down during operation and does not restart (fault code F29).
Cause: Gas cut-off, flue gas recirculation, condensates, or faulty grounding.
Have a technician check it.
08
The boiler does not ignite and the display shows a fault code for ignition (F.28 or F.29).
Cause: Flame not detected. The most common causes are low gas pressure or a faulty ignition electrode.
Open the gas shut-off valve and press reset once. If it repeats, have an official technician check it.

Fault codes Saunier Duval that require diagnosis

Code	Fault	Technical checks
F00	Return temperature sensor (NTC2) disconnected.	Check if the sensor connector is loose. If it persists, have a technician check it: it could be the sensor, the cable, or the PCB.
F01	Return temperature sensor (NTC5) disconnected.	Just like the F00: check the connector and, if it persists, have a technician check it.
F27	Flame detection fault: the flame control is not reliable.	If it occurs when turning on or off, have a technician check it: it could be moisture in the electronics or the flame control.
F28	Ignition fault: the burner does not ignite.	If it repeats, have a technician check it: it could be the gas, the ignition, or the PCB.
F29	Flame loss during operation.	If it repeats, have a technician check it: it could be a gas cut-off, flue gas recirculation, or a faulty ground connection.
F61	Gas valve activation fault.	Have a technician check it: it could be the wiring of the gas valve, its coils, or the electronics.
F62	The gas valve does not close in time after the flame goes out.	Have a technician check it: the gas valve or the PCB are the suspects.

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.

indicate that the PCB is located behind the front panel, in the control box, and that the reference is usually printed on the circuit or on a side sticker. In our unit, the references are 0020035375 and PM-02. Also compare the number and position of relays and connectors.

Is it compatible with my Saunier Duval Themacondens F24?

The compatibility of this variant is pending confirmation. Registered application: this PCB (0020035375 · PM-02) for the Themacondens F24. Additionally, different sources provide the code 0020035375 for the Thema Condens F 24. Registered designation: "Thema Condens F4".

Does it also work for the Thema Condens F24 E or the F25?

The compatibility of this variant is pending confirmation. It is not confirmed and there are contradictions. Some indicate it with 0020035375, but two British websites list 0020018478 for the F 24 E, a SAP catalog 1652 lists it as the main PCB for the Thema Condens F AS 24 E, and a nomenclature, with mixed rows, points to 0020212695 for the F25. Check the marked code and call us at 911 17 77 77 or send a photo from Contact.

Is it the same PCB as 0020018478?

they contradict each other: 0020035375 for the Thema Condens F 24, but the URL of the technical sheet ends in 0020018478 and relates that code to the Themafast Condens F 24 and F 30. Two British websites list 0020018478 for the Thema Condens F 24 E. No documentation states if they are the same PCB. Compare the code marked on your PCB and call us at 911 17 77 77.

What do 0020035375 and PM-02 mean?

0020035375 is the reference with which this PCB is advertised for the Thema Condens F 24; one refers to it as "OEM reference." PM-02 is the circuit designation marked on the part. Without additional external confirmation, they are linked, and no official breakdown read mentions 0020035375: they are only marked together in our unit.

What symptoms point to this PCB?

To confirm: the boiler does not ignite or respond to the panel, erratic fault codes, clicks or stuck relays, burnt or oxidized traces, and spontaneous resets. There is no official table read, so it is advisable for a technician to diagnose it.

Who should install it and what adjustments are needed?

To confirm: A qualified technician: the PCB operates with 230 V (power connector) and the boiler runs on gas. Our unit also has a 24 V auxiliary connector and a 24 V DC Schrack relay. He says that complex adjustments are usually not needed.

How to identify this PCB?

Compare the silkscreen, the distribution of the connectors, and the exact variant of the circuit with the photographs.
