I had a good contractor to build my exercise pool(Roger Olson, Tropical Dream Pools, Midlothian, TX). The only problem was his choice of controls: Pentair Troy Barron gave poor service, and now I suspect he sold Roger a much more complex system than i needed(there is no light, no spa). He gave a very hurried instruction, answered a few phone calls, and then stopped answering my calls. I eventually called the Pentair customer service number, who sent out a factory certified installer(Tony Roper, Advanced Pool Care, Weatherford, TX). He rewired parts of the panel, moved the remote antenna, and replaced the defective remote controller. It has worked great for 6 months now.
