Hmmm... Low voltage. I'm not sure what the voltage requirements are for that thing, but sometimes voltage problems are inherent in a system due to poor planning electrically.

For example, my pool builders placed my pool pump and electrical system as far away from my home electrical service as possible. (That's another story.) The result is that we needed 150 feet of cable to get power to the pump. With a run that long you have to take into account the resistance of the wire and your current demands to figure out the VOLTAGE DROP caused by the long length of wire. Our cable had to be larger than what the equipment typically calls for to overcome the voltage drop (larger cable has lower resistance, thus less voltage dropped for the same amount of current).

All this to say... IF your pool electrical is more than 50 cable feet from your household supply, the low voltage problem MAY be due to improperly sized wire and not the equipment that is showing the symptoms. You may need a qualified electrician to assess the situation for you.
