[Z3 E36] Elettroventola a due velocità - controllo e risoluzione collegamento errato

[resunoiz]

sì, per essere "in regola" dovresti invertire anche 2 e 3.

e in effetti sarebbe meglio, perchè, se per caso l'interruttore termico che scatta a 80°, si blocca, non partirebbe neanche la seconda.

motivo? :neutral_think: :?
ecco come dovrebbe funzionare il bulbo:

when the double temperature switch reaches the 'high' trigger point, all three contacts are joined internally, so at that point it doesn't matter which wire goes where. I have dismantled one of the switches and the way it works is that there are two contacts that are moved by a single plastic shaft, connected to a pair of metal discs that move the shaft as the temperature increases. First one contact is earthed, then the second is also earthed, at which point all three are connected. As the high speed relay kicks in, it cuts power to the low speed relay rather than having the double temp switch do it, presumably to avoid the danger of a 'dead' area between low and high which could occur if the switch was switching off the low at the point it was switching on the high.
