Produkt zgodny z opisem, działa bez zarzutu. Warto od razu kupić czujnik temperatury, co powinno być zaznaczone w opisie. Podczas wymiany okazuje się, że czujnik w starej listwie jest na stałe zgrzany z listwą.

Schnell geliefert, leider nicht die 544.18 sondern 544.22. Dort sind die Map Ausgänge an der Rückseite statt seitlich. Musste die ganze Gasanlage neu verlegen, viel Aufwand. Sonst alle OK.
