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 the marking 03101009 00 A1 (with 95/05/12) on the plate and the label 100132 F (96-17). These are the codes for our unit.
Look at the final letter of the version: this one has 100132 F and also 100132-G. The documentation does not state that they are interchangeable.
Check the fuse F1 (silkscreen "Fuse 125mA T") and the SCHRACK RS420024 relay of 24 VDC: they must match those on your PCB.
To confirm: Do not confuse it with 05712800 or 288.66.0016: 05712800 and 288.66.0016 are for the THELIA 23 E, but the documentation does not link them to 03101009 00 A1.
Also with 1163835, as a technical sheet is available for THELIA 623/23E and THEMIS 23E/23EV. Always compare the code marked on your PCB.
if they match, call us at 911 17 77 77 with the model of your boiler.

Before purchasing

To confirm: Saunier Duval 155E — 1 origin: from the same code 03101009 00 A1
Do not confuse: 05712800 — PCB for Saunier Duval that is for the THELIA 23 E: (code PEX 109008, after 1993) and (Thelia 23E/623E, refurbished) — Another code; in what has been read, neither 03101009 nor 100132 appear.
Do not confuse: 288.66.0016 — Multifunction module compatible with THELIA 623E, THEMIS 23E, and THELIA 23 E (after CE) — Another code; in what has been read, 03101009 and 100132 do not appear.
Do not confuse: 1163835 — PCB that a data sheet provides for THELIA 623/23E and THEMIS 23E/23EV — Another code; in the read data sheet, 03101009 and 100132 do not appear.
05712800 is listed as the PCB for the THELIA 23 E, and I haven't found 03101009 mentioned. Confirmation recorded: 03101009 00 A1 for the THELIA 23 E MOD.2.
Join 03101009 with a Saunier Duval PCB: with model 155E, in its sheet 100132-G, with Thelia 23 E; its sheet 100132-F lists version 100132-F for the same boiler. No official breakdown available. Registered boiler.
Pending confirmation of registered applications by model, variant, or programming: Saunier Duval THELIA 23 E MOD.2.

Frequently Asked Questions

Frequently asked questions: Saunier Duval

Where is the code for this PCB and what other markings should I compare?

On the PCB, the marking 03101009 00 A1 (with 95/05/12) is present, and on its label, 100132 F (96-17). Also compare the fuse F1, rated at 125 mA T (screen printing "Fuse 125mA T"), and the SCHRACK RS420024 relay with a 24 VDC coil. The same 03101009 00 A1 also indicates a 125 mA fuse.

Is it compatible with my Saunier Duval THELIA 23 E MOD.2?

The compatibility of this variant is pending confirmation. Registered: for the THELIA 23 E MOD.2. It offers PCBs 100132-F and 100132-G for the Thelia 23 E without indicating MOD.2. If your boiler is another version of the Thelia 23 E, compare 03101009 00 A1 and 100132 F with your PCB, send us a photo from Contact or call 911 17 77 77.

What is the difference between the 100132 F and the 100132-G?

list the two as "Electronic Version" of PCBs for the Thelia 23 E. The technical sheet for the G lists the identifier 03101009. Our unit has 100132 F along with 03101009 00 A1. The documentation does not specify if F and G are interchangeable: compare the letter of your PCB.

What do 03101009 00 A1, 100132 F, and 95/05/12 mean?

03101009 00 A1 is the marking on the PCB: it gives 03101009 as the identifier and shows the complete code ("Oznaczenie: 03101009 00 A1"). 100132 F is the marking on the label; write 100132-F and 100132-G with a hyphen and refer to them as "electronic version." 95/05/12 and 96-17 are marked on the PCB and on its label; the documentation does not explain them.

Is it the same PCB as 05712800, 288.66.0016 or 1163835?

The documentation does not link them to 03101009 or 100132. It provides the PCB 05712800 for the THELIA 23 E; lists the module 288.66.0016 for the THELIA 23 E (after CE) and a technical sheet for the PCB 1163835 for THELIA 623/23E and THEMIS 23E/23EV. Registered confirmation: 03101009 00 A1 for the THELIA 23 E MOD.2: compare the code before ordering.

What fuse does it use and what should I do if it is blown?

To confirm: It uses the F1 fuse of 125 mA T (screen printing "Fuse 125mA T"). The same board also indicates 125 mA, and the spare parts list for the Thelia 23 E includes a 125 mA fuse (S54081, pack of 5). Replace it only with another identical one, of 125 mA T like the original. If it blows again, have a technician check it.

Can I install it myself?

It must be installed by a qualified technician. If you have doubts about compatibility, send us a photo of the label on the PCB and the data plate of your boiler through Contact.

How to identify this PCB?

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