What does this switch do?

The one in the upper left corner? I have a 2017 Voltage 3305. Also the tank heater switches-which switch to which tank?

Just a wild guess as I have the same style switch on my 2014 3950 but in a different location of the control panel - awning lights?

As far as which switch for which tank heater, it is a guessing game unless get out a multimeter and drop the belly covering.

The awning lights are controlled by the electronic panel but I’ll check it out.

That switch is more than likely for the rear outside steps. There is a small amber light under the step for night time. Dutchmen seriously needs to invest in a nice labeling system (its 2021 guys - come on).

What he said except it actually controls the step lights on the rear AND front steps on my model which is a 2018. I think the newer Voltages don’t have the small flip up steps in the front anymore so in that case just the rears.

And good luck figuring out which tank heater racy of the three switches controls! I would suggest use logic and then the reverse would be true. If I’m a cold environment I would just make sure all holding tanks have at least some waste in them and use all three at the same time although I bet they draw quite a bit of power as most things that heat do.
