Centrala Viessmann Vitodens 300 eroare burner control unit

Recommended Posts

In caz ca va loviti de asta... defect de centrala veche.


Simptom: daca ii ceri caldura, da doar drumul la pompa dupa care nimic. Nici macar nu da drumul la suflanta. Sta si asteapta.


In coding 2 registrul 38 (Status burner control unit) apare 33 in loc de 0.


Problema: pe placa electronica langa intrarea de la senzorul de flacara (X6) e o intreaga poveste. Langa un transformator mic si clasic (parte din circuitul de detectie) e un 0.22uF X2 275V care in cazul meu mai masura 0.025uF, parte dintr-un circuit care are legatura cu "detectorul de flacara e functional". Vezi poza atasata.


Sarbatori fericite!
