Short version: How does the override function work on a variable speed pool pump?
Long version: I recently bought a Pentair Whisperflo VST Variable Speed Pump which replaces an older Pentair fixed speed pump.
My pool guy set it for 2800 RPM for seven hours (on Speed #1) which is fine. It will reduce my pool energy consumption by half compared to what I got from the older pump.
(Speed #2 and Speed #3 were left unprogrammed.)
But reading through the manual, I see there is an "override" function. I was expecting this to mean that while the pump was operating the scheduled program, I could change the speed temporarily, The intent would be to try out different speeds on my own without the pool guy knowing*. (He wouldn't know since once the override ends, it reverts to the scheduled programming.)
Anyway, that's how I thought it would work.
But playing around this morning, it seems the override actually means that you can only override one scheduled program (i.e., Speed #1) with another scheduled program (i.e., Speed #2 or Speed #3). But since the latter two both are zero in my case, no override of any kind is possible. More importantly, I can't just override the #1 Speed program using a speed of my own choosing for testing.
Am I doing something wrong, or is this truly the way it's supposed to work?
BTW, I searched the troublefreepool forums for an answer and found none. But they're pretty unamimous in the belief that lower pump speeds and shorter hours are fine for most pools and favor speeds lower than 2000 RPM. I really don't need to go the lower-speed route -- halving the energy costs is wonderful enough -- but a slight further lowering of the speed can reduce it to a quarter of my prior pool energy costs. I figure it would be worth a try.
* The pool guy is great but he prefers that his customers don't stray too far from his own ideas on pool operation.
