I have a Hayward VS pump with a built-in timer. I'm installing an AQR-15 SWCG and the instructions say that it should only be on when the pump is running. Is it that important to run the AQR on a separate timer - coordinated with pump run times? Would it be asking for trouble, long-term, to hard wire it without a timer and let the flow switch control it? BTW, an automation panel is out of the question. Thanks!
