regarding the use of ramping. You may want to use it. If you turn the controller on without ramping, you end up hammering the Controller with a huge error in the beginning. Depending on the response of the system, you could end up with Integral windup. This can cause large overshoots as the system tries to come into control
Derivative can also be used to minimize overshoot. It may take a while to get the gains set for your system, so a couple run throughs with water will help. I didn't read the manual but most controllers have auto tune these days and can help minimize the screwing around generating the right gains.
