Review: Da uns ein Stellmotor unserer Fußbodenheizung kaputt gegangen ist, kam dieser hier im Vine-Programm gerade recht. Er war sehr einfach zu installieren, wie die meisten Stellmotoren. Der Preis ist sehr gut. Der Stellmotor arbeitet jetzt seit etlichen Monaten einwandfrei.
Review: E' pienamente compatibile con le valvole standard per impianti di riscaldamento e fa il suo dovere. Raccomandata!

Vannes de régulation des circuits de chauffe : Installation facile, fonctionnent bien. Contrairement à la présentation du vendeur, la course et la puissance d'appui ne sont pas réglables mais ça fonctionne dans mon cas. Les régulateurs de température WiFi pilotent tout ça sans problème. Les indicateurs rouges de positionnement suffisent malgré leur faible taille.
