Maybe a decent place to implement a computerized linear search algo for your techs?
Sounds like they're setting params for a PID/control loop in the first place and second order PID/control loops are notoriously finicky so I'd avoid that. But a simple/static linear search for params where it just binary searches while the tech chooses the best value amongst the 3 options [min, mid, max] probably gets them there pretty fast. Though probably still not faster than a manual dial.
