The ideal temperature will vary depending on your location and how far above sea level you are (pressure).
However, I always use heat in my QWISO purge, it greatly speeds up the process and allows for evaporating off the last bits of solvent that are left in the shatter at the final stages of purge.
One good way to ensure that you fully purge is to apply a low constant and accurate heat until you have a visible wax/shatter with no large, irregular bubbles. The smaller more uniform bubbles are decarboxilating terpenes (in my understanding), whilst the larger irregular shaped bubbles are trapped solvent.
Hope this helps, my friend!

Really? Not even going to wait for a second opinion? ; )
There are temperatures at which each cannabinoid or terpine boil off. There is also a temp at which decarboxylation takes place and THC is converted
Air pressure does have an effect on boiling points but FWIU you'd have to be on a mountain top, in a trench or in a vacuum for it to have any measurable effect.
The lower the pressure, the lower the boiling point, This is why people purge in vacuum ovens. They can reach temps required for a complete purge without sacrificing volatile terpines or unwittingly decarboxylating.
None of that really applies to your situation since (I assume) you are not purging in a vacuum oven but in a pyrex dish or something like it.
Slow and low will give you the best smells, flavor and potency. You don't need heat at all. Just leave it overnight. Don't evaporate too much at once. Just a thin layer at a time. Slow and low.
A small fan blowing on it to agitate the surface will speed evaporation considerably. Cover with something that will allow air to pass to keep dust and other contaminates out.
