My united spa has a timer for the filtration. I can set it for 24 hrs. and the pump runs on low 24/7. This is how I currenly run my tub. I can also set the timer to come on and off at different intervals, however, when I do this, the pump kicks on in high speed, not low. This seems odd to me. I don't have an owner's manual and can't find any schematic for this system. Shouldn't the pumps turn on in low speed when the timer kicks?
