Water Control Unit Application


We are working on a custom water temperature unit that will consist of a motor, temperature probe, and valve automatically adjust to temperature changes. My question is what kind of processor should I look at for the monitoring. We'd also like to have a simple display along with it. I have experience with PLCs, but I would think we could get away with using something a little more simple. Any ideas would be great.

Google single loop controller.
Match temperature sensor type to what controller can handle
Match controller output to valve actuator/positioner input
