This document provides a wiring diagram and system overview for a heating and pumping system. It includes labels for components like the heater on/off switch, pumps, motors, contactors, and circuit breakers. Wiring shows how these components connect to the control circuit and CompactRIO controller. Diagrams depict the signal flow and an instrument loop with the temperature sensor wired to the controller. The system controls water temperature using pumps based on sensor readings by the CompactRIO.
