I live in SE Texas and it is supposed to get cold here (anything below freezing is COLD here) tonight. I checked and my freeze protect is set a 34, and it is programmed to run the filter pump. Is that all I need to run? What else, if anything, should I check to freeze protect. The menu allows me to check the spa, low speed (Jandy two-speed pump), cleaner, and lights. Any advice appreciated. Thanks.
