It sounds like either the circuit or the pot are non-linear on the PW adjustment. If its the pot then a different pot will help. If its the circuit then you'll just have to live with it.
Getting to 120°F seems to be a bit on the too warm side but then again on a dewy summer night you do need to go above ambient. Having the heater on an EP that has most of its surface exposed to the air will probably reduce this temperature.
