I know this topic is well worn, but my Pentair system in freeze protection, while swapping between pool and spa mode every 15 minutes slowly drains the spa over a 24 hour period. I assume there is some loss of water each time it switches and I know there could be a bigger problem to solve. For now, my question is whether I can shut off freeze protection and set up a schedule switching from Pool Mode to Spa Mode to Spillway every 15 minutes to create freeze protection with spillway mode inbetween to keep the spa topped off.
Thoughts?
