I have a Poolpilot and 2 speed pump. I had to put the Poolpilot on a timer. The 2 speed pump always has power applied from the Poolpilot while the Poolpilot is on. It only lets you program times from low to high. Set the timer for ON at 5am and the Poolpilot comes on and runs on low for 1/2hr and Program runs pump on high for 1hr then turns off. Causes the pump to run on low until the next program point 5pm, back to high for 1hr. Timer turns OFF poolpilot 6:30pm. I'm running a 2hp pump, don't know if it can handle the surge of two pumps coming on.
