Hi folks. First post here. My system, described below, was built in 2013. Service guy recently replaced the Aquapure Tri sensor for "No FLow" alert. Aquapure now working. Later that same day, the pool LED lights turned on, ahead of the normally scheduled time. They will not shut off or respond to the PDA. I tried pressing the reset button on the control box, powered down and removed the 9V battery with no luck. The LED lights remain on as soon as power is restored to the system. Spa lights and all other features work fine. Any thoughts? Thanks.
