What does fault code 13 mean on Chaffoteaux?

Main circuit board fault. The main PCB (S1019000) does not pass the internal self-diagnosis; it is usually due to an electronics/EEPROM fault or the board not generating its internal voltages. Check 230 V input, fuse, and low voltages (5/15/24 V) on the PCB; if they are correct and the wiring is OK, replace the board.

What does fault code 20 mean on Chaffoteaux?

Communication defect between the user interface and the main board. Fault in the communication/ebus channel on the main board, incompatibility between interface and PCB, or defective connection/harness. Check the power supply to the interface from the board, connectors/harness, and test with a known interface; if it persists, the cause is the PCB.
