There is a setting which increases or decreases the toasting time. But it effects both the buns and the hot dogs.

Yes adjust the temp it will take a little longer to cook the dog but you can put your bun in 1/2 way through the cook as well..

No, there is one setting button that controls the whole inside just like a bread toaster.

yes from to light to dark.just like a toaster

Yes it has the same kind of settings knob as on a toaster

No. The buns rest against the walls behind the hot dog cooking elements and heat up. I generally take the buns out after running the cooker on setting 2 and then run it with just the hot dogs for another round on setting 2.

The toaster settings is by numbers for how hot/cooked you want hot dogs and buns.
