I liked the On-Command controller, and EcoStar concept. Got one set for my spa, and one for my pool. The spa system works great. The On-Command works great. The first pool pump failed within moments (even before I hooked up the interface.) The second pump worked perfectly for 6 months and has just failed. In both failures, it seems like the VSP internal drive board failed. The VSP communication interface works with the On-Command, but it cannot interface with the internal drive board - serial number comes up 0, the internal drive board temperatures come up 0, and the power consumption comes up 0. The EcoStar interface shows an error code: "low AC voltage 20 cycles ago," but I don't know how to clear this. I powered off over night, no help. Any help would be appreciated.
