Think I got things more straightened out in the programming dept now. Big thanks.Rich,
My post number #45 shows just what you need to do to run a set of schedules that change the pump speeds at different times. The two main things to remember are that slowest speed needs to run the entire time the pump will be running. Normally this would be the Pool Circuit no matter what you named it. And that when the pump sees two schedules at the same time it will always run the fastest one.
If you turn any scheduled item on or off manually, depending on when you do it, it will screw up the schedule and will often skip the next schedule. It will then catch up the next day. I did not invent it, I am just reporting how it works.
The main item that I don't recommend turning on or off is the Pool mode icon or the pump/filter ("F") button on the panel..
Since you can run an IntelliFlo at a low RPM for about $20 bucks a month, there is just no reason to not allow the pump to run all day or more. This also gives you better skimming..
That said, it is your pool and you can run it anyway you see fit.
something restrictive in the heaters themselves that necessitates more spin to get water over a typical weir door?
