But you helped me to find a mistake I did. For constant voltage i have to make a voltage dividor between 5V and GND!!!
I made two voltage dividors for each temperature channel and now all seems OK.
I'm sorry for the confusion
Now both channels react identical.
That means the error only arises when the speeduino is connected.

Then its parallel with the bias, I thought it should go to ground.
