    Polaris Watermatic C2000 ORP/PHG Controller with Spa

    We are adding a C2000 controller to my year-round spa in Chicago. I am a little concerned that the flow cell & sensors could still freeze during a real cold spell. The low speed pump on my spa runs between 6 and 8 hours a day depending on temperature. Any thoughts on how to insulate the flow cell to ensure it doesn't freeze or should I just find a way to run the water lines into my crawl space somehow and put the flow cell there even though it will be a total pain in the *** to move it there.

    The manual says to ensure that the sensors can't freeze remove them from the unit. Since it's a year round spa I'd insulate the unit with a foam lined box and make sure your automation system has a freeze protection feature and that it's activated.
