It doesn't have to be a T&D pool - any pool with full automation will have freeze protect built in. That includes Hayward Omni series, Pentair EasyTouch, and Jandy iAquaLink (these are the 3 major players in pool equipment).
Freeze protect is part of the operating system in these automation systems.
Having said that - we haven't been at freezing for anywhere near long enough for a pool to get frozen lines. We only hit 32 for a few hours, and lines are buried at least a foot deep. Even so, it doesn't hurt to run your filter overnight - if you have a VSP pump, you can run it at a very low setting and it'll cost you pennies.
