Hi,

As I recall you have to upgrade first to 3.0.0.

All of the steps are documented somewhere.

It works .. Thanks for the Help !

@Phaedrux

Changed crimp, terminals, wiring with the same thermistator..

Now, i changed thermistor with the same wiring/terminals and works fine.. So it was the thermistor.

The thermistor its new.. i open the box three days ago.. Very weird..

@Phaedrux Thanks for the help.

I will try changing the thermistor for a new one ! Thanks for the help and your time !! I keep you updated

@deckingman Could any other wire be making noise? because the thermistor is new, and the wiring its from stock on this moment.

bad crimp ? bad cable ?
