Hi all. I am a noob pool owner. We just had an inground pool and spa constructed this past summer. Our pool was shut down for winter this last week. We are keeping the spa open year round. Last night it got down to below freezing here in the Northern suburbs of Chicago. We have a Pentair system (pumps, filters, Intellicenter, etc) and the Freeze Protect kicks on when outside temps hit 32F or below. When that happens the jets and the air blower turn on in the spa and cannot be turned off. The problem is that water spills over the top of the spa and it is quite a mess. This will create an icy hazard once we get into the heart of Winter. I know that we can adjust the Spa pump (IntelliFlo VSF) down but the air blowers are just going at full speed. Is this normal? My pool builder said this is normal and once I have the spa cover installed, the problem should go away. Any insight is appreciated.
