Freeze protection pump speed

[JeffSNC]

Hi all...new member with a new pool, approx 20k gallons, in NC with tempa that will drop in teens or 20s every now and then but not regularly.

I have freeze protection set to 42deg but question is, for the pump timer at night when normally it would be off, what rpm should I set it to in case the freeze protection comes on.

Currently have it at 1,000 rpm. That a save and not too costly/noisy setting?

Learning a ton here, thanks!

You should set your freeze protection temperature lower. You really don't need the freeze protect to kick in until the air temperature gets to 34-36F range. Running it as high as you do is just wasting energy moving water for no good reason. As for speed, you can simply run a programmed pump speed that is set to just barely move water through the system. If you can feel water flowing out of your returns at 1000RPM, then that's sufficient.
