The pump has 4 programmable schedule modes plus a programmable "quick clean" manual mode. Each programmable modes can have its duration and RPMs customized and fine-tuned if desired. However, its presets work for many people. The Speed 1 preset is 3000 RPMs for 2 hours, which helps ensure that you successfully prime the pump every time and get a little bit of the high-flow circulation that any pool needs. You can its presets under "Using the Default Schedule" in the manual.
