I’m out of town and we were about to hit 25F for around 48hrs. My wife doesn’t know how to work any thing so i was able to get her to enable cold temp pump run and set the heater to the lowest setting possible. Definitely going to cost me some cash but better than pool damage was my thinking. If I was home I would of figured out a better solution but I’m not and I didn’t...Thank you for the post, appreciate it.
