Hi, Working with SewerGEMs, GVF-Convex solver. I need your assistance in setting up a VSP or VFD with the below on and off (elevations) controls. I want to use the fixed head VSP type and use my...

The 'Decision Type' in Darwin Scheduler is independent of the setting in the main application. If you pick a pump for use in Scheduler you can specify whether you want it to act as a fixed speed pump...
