I don't think knobs are necessary for this. The system is designed so that you can use a momentary button to change a circuit between preset duty cycles (read temp levels). So you can cycle between say, 0%, 50%, & 100%. The indicator LED will blink telling you the circuit affected (by color) and the duty cycle selected (by blink speed).
Like the single channel board in the attached video.

Will any of the features mentioned allow me to control my heated grips like a heattroller(sp ??)?
If so, will I be able to attach a rotary type switch to do the controlling, or will I need to whip out my smartphone everytime I want to change the temperature?
