Default BCS-460 Violent Boil - turn down?

Hi Guys,

I've brewed a few batches on my new electric BCS-460 system and I've noticed that when im boiling I tend to have a very violent boil.
The problem is, if I set the temp for 212, the boil is very violent, and then once the temp reaches 212 it shuts off - once it falls down a few degrees it takes back off again and works it way back up to 212 then shuts off again. I get that this is the point of reaching a temp and shutting down but is there a way I can hold a constant temp instead?

Instead of using a temperature setpoint for boiling, I would suggest directly controlling the the element. Also, you can lower the "duty cycle controlled" percentage to something less than 100% to control the intensity of the boil.

What I do is set my state to heat until it reaches 192 which is just under boil (for my location boil is 195) then it switches states to be in PWM mode (default settings) at 50%. Here is what that looks like.

Thanks for the info guys, this is what I was looking for. I completely forgot about adjusting the duty cycle. I'll be testing it out this weekend.
