Ok, it just crashed.

But it seems to work.
The secondary star was about 3AU from the Sun or more or less 450 000 000 km, that's closer than Jupiter.
There was plenty of room for the planet to orbit around the small star.
The software only tells me the average temperature of the planet, not in a particular region.
The revolution around the star was just a few days and temperature fluctuates moderately.
When the planet is located between the 2 stars, it's hotter and colder when it is further away from the main star.
The variation was about 10 or 12 degrees Celsius. That seems a bit high but you knows.
So the Sun does play a non negligible role on the planet climates even at that distance.
The part facing away from the red dwarf would face the Sun and could have temperatures close to the freezing point, maybe above.
That would make that side much less inhospitable.
