Maksymalna zmierzona temperatura podczas pracy kotła to ok 80-90 stopni, gdzie mierząc w tym czasie inną termoparą podłączoną do multimetru rzeczywiste temperatury wynoszą powyżej 150 stopni.\r\n\r\nZałączam plik z odczytami z terminala, może w czymś pomoże.\r\n\r\n[Sterownik- terminal.txt](https://github.com/uzi18/sterownik/files/756132/Sterownik-.terminal.txt)\r\n\r\nDodatkowo zauważyłem w odczytach z terminala komunikaty: TRIAC: zaklucenia z detektora...\r\nDmuchawa nie jest \"czysto\" sterowana, przy mniejszych mocach słychać nierównomierną pracę. \r\nSprawdziłem przebieg na pinie 2 Arduino, wygląda jak poniżej, wydaje się być w porządku.
