I live north of Houston. Usually about 5 degrees cooler at night here than Houston. A couple weeks ago we had a cold spell. Never got to freezing temperatures. Maybe 38 in the morning. I could hear my pump running on hi speed early in the morning. The display read freeze mode active. I have a Hayward max flo vs 500. I have read the manual and I do not see any information about freeze mode. My desire would be to lower the rpm during freeze mode. Is that possible? Set a timer or mode and manually set it for near freezing temperatures?
This is my first pool and first winter approaching. I appreciate any thoughts on what to do.
Thanks

Pentair is the same. It gets the temp from Accuweather, then I guess to be safe starts the pump at 38 degrees, then doesn't shut off until 43. I've adjusted ours to 36 when dropping and 39 when rising.
