I upgraded to a Hayward W3SP2603VSP pump and am having a hard time figuring out the settings to have it run at a set speed until I manually change it. Pump is stand alone, no automation. The way I read the manual if I set the start and end time as the same the pump would just continue running and not shut off. Last night it shut off with the timer set 12a-12a. What am I missing? Anyone share their settings?
