I've been perplexed by the random behavior of my EasyTouch controlled VS+ SVRS pump for a couple years. It would stop, restart, pump for a while, stop again and repeat this cycle. Sometimes it would all work great and sometimes not. Recently, it would start, step up to full prime speed, then settle at my run speed of 2000 RPM. Then it would step up sometimes to full speed, sometimes just a few steps, resettle and repeat the cycle.
After tweaking every setting I could, I found that running my system in "Service Mode" which disables the EasyTouch panel and enables the onboard pump controller, the pump behaved as expected.
Yesterday, Pentair came out and updated my firmware from 2.06 to v2.10, no charge. So far so good! Thanks Pentair!
