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.

Look for 0310144400N14 printed on the PCB (sometimes on a side sticker) and the designation SYMSI7.0.
Compare the number and position of relays and connectors: under the same code, there are different versions.
Do not confuse it with 0310144400R18, S19, L12 or 0310144400015: they are different codes. Sell the 015 for the ThemaClassic F 25 E with three relays in 2 + 1; Not confirmed: if it is the same circuit.
Compare the silkscreen code: 06V0-A also appears in the R18, and we have no marking data for S19, L12, and 0310144400015.
Check the model on the rating plate: Themaclassic F25 E, Themaclassic C25 E, Themafast F25 E H-MOD, and Themafast C 25 E are confirmed.
If they match, call us at 911 17 77 77 with your boiler model and we will reserve it for you.

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.
Cause: A technical sheet associated with this PCB. First, check the 230 V.
02
Erratic errors on the screen, restarts in the middle of a cycle, stuck relays or burnt tracks.
Cause: According to reports, erratic faults may occur without any real physical cause; stuck relays and burnt tracks may happen "on occasion."

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.

Before purchasing

To confirm: Saunier Duval Themaclassic F 24 E, Themaclassic F AS 30 E, Themafast C 24 E, Themafast C 30 E, and Thematek S F 24 E.
To confirm: Saunier Duval Themafast F24 E, F25 E, F30 E, F30 E-A and F30 E H-MOD
To confirm: Saunier Duval Thema C24 E V —, the PCB of this boiler is the R18; Not confirmed: if the N14 fits.
To confirm: Saunier Duval SF24E, the PCB of this boiler is the R18; Not confirmed: if the N14 fits.
Do not confuse: 0310144400R18 — SYMSI7.0 PCB from the Thema C24 E V and SYMS17.0 PCB from an SF24E — Another circuit code. Both have the marking 06V0-A, which does not distinguish the N14.
Do not confuse: 0310144400S19 — Another version of the PCB — Another code. It comes with four relays (the N14, with three) and also for the Themaclassic F 25 E and the Themafast F 25 E H-MOD, which Confirmation registered: with the N14.
Do not confuse: 0310144400L12 — Another PCB code SYMSI7.0 — it lists with the S19 for several Themafast (F25E, F24E, F30E and H-Mod), without N14.
Do not confuse: 0310144400015 — OEM reference from another sheet of the ThemaClassic F 25 E, in another sheet, it is given for the ThemaClassic F 25 E, which Registered confirmation: with the N14. It does not mention N14 or SYMSI7.0 and describes three relays in 2 + 1, like the N14: the number of relays does not distinguish it.
To confirm: they connect the N14 to a PCB: (N14 and SYMSI 7.0) and (N14). From (N14, spelling SYMS17.0) it does not identify the seller. They provide S1047000 as the main PCB for the Themaclassic F 25 E; none connects it to N14.

Frequently Asked Questions

Frequently asked questions: Saunier Duval

How do I identify the SYMSI7.0 0310144400N14 PCB?

Look for 0310144400N14 printed on the PCB (or on a side sticker) and the designation SYMSI7.0; some write it as SYMS17.0. Our units also have the marking 06V0-A and the name Sung Wei, but the R18 also has it: this is not enough to distinguish the N14.

Is it compatible with my Themaclassic F25 E, Themaclassic C25 E, Themafast F25 E H-MOD or Themafast C 25 E?

Yes, all four are confirmed. Additionally, it is compatible with the Themaclassic F25 E and the Themafast F25 E H-MOD, both with N14.

Is it compatible with other Themaclassic or Themafast (F 24 E, C 24 E, C 30 E, F 30 E)?

they list them with N14, each model separately: to be confirmed. Send us a photo of your part's label and the boiler's PCB from Contact, or call 911 17 77 77.

What is the difference between the SYMSI7.0 with codes R18, S19, or L12?

These are other codes. The R18 appears in French (Thema C24 E V) and in (SF24E). It provides the S19 (four relays; the N14, three) and also provides S19 and L12, also for boilers that Confirmation registered: with the N14. Without additional confirmation, it explains neither the difference nor states if they are interchangeable.

What do 0310144400N14, SYMSI7.0, 06V0-A, and 4000140782 mean?

0310144400N14 is the circuit code. SYMSI7.0 is the designation of the PCB family. 06V0-A is the marking of the PCB, along with Sung Wei; R18 boards also carry this marking. 4000140782 111-8140 is another marked code; it explains itself without additional confirmation.

What reference do they provide for this PCB?

To confirm: S1047000 is listed as the main PCB for the Themaclassic F 25 E, and it is linked to SYMSI7.0. None connect S1047000 with the N14: we do not assert that they are the same.

Who should install it?

A qualified technician: it is the electronics of a gas boiler at 230 V. Cut off the power before touching it.

How to identify this PCB?

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