Wow, your experience is exactly the same as mine. Right down to getting the same response from Cody at poolpartstogo. I will add one more observation that I think you experienced as well but may not have realized it, and that is, when you manually start and stop the pump using the pump panel, and then go back to using the pool automation system (for me its Jandy AquaLink) the pump will run steady for eactly 24 hours, even with multiple automated starts and stop, but after 24 hours since the manual start/stop, the pump will do exactly what you described - cycling off and on every 60 seconds exactly. As a mechanical engineer with industrial control systems experience, I have a hard time believing this is a solder joint issue - the precise 60 second intervals and the precise 24 hour delay time tells me this is 100% a programming issue of some sort. Its as if the two systems are fighting with one another. I note that the pump panel does have its on "schedule mode" which will run the pump for a maximum setting of 24 hours. It seems like pump is to shut itself off after 24 hours and then the pool automation keeps turning it back on, and then after 1 minute, likely the shortest programming interval time, the pump panel again tries to turn the pump off because it still registers 24 hours of run time. It seems like the only way to reset this clock is to manually turn the pump on and off, and then the 24 hour clock starts all over.
