But what "control" do you have to take? When you boil you don't ever change the setting. For your setup, for the amount of water you boil, you find what duty cycle is needed and then use it for all your batches. There's nothing to adjust during the 60-90 minute boil.
My boil usually goes something like this:
(1) Set duty cycle to 100% to get up to boil.
(2) Once boiling, reduce to 85% and maintain for entire duration.
(3) When boil is done, turn off boil.
You can certainly watch the boil the whole time, but there's no need to constantly tweak or adjust the duty cycle. That would indeed probably be easier with a rotary knob, but it's not required.
I'd stick with the 1 PID to do it all. It makes it simpler.
