I have a Pentair VS controlled by an iaqualink RS. When I command the pump to any speed with the Iaqualink, after 15-20 minutes the pump will revert to the "Pool" setting speed. I think either the aqualiknk commands the pump to "pool" speed after 15 minutes or the Pentair pump has a timer function that I'm not aware of and reverts to no. 1 speed after 15 minutes. Has anyone seen this problem? I would like to set the pump at a low speed for several hours to save on electricity in costly CA.
