I should have been more specific - MY water is so less likely to freeze. Where I live, we simply do not get the hard freezes as in other areas and so water just won't freeze easily. If the water is moving from the pump running, then it would take a freak accident of nature to make it freeze ... which, I get in your case, as Texas was hammered last year with that winter storm + power outage. All I'm trying to get across is that you really just need to do the minimal amount necessary to keep the water moving and you'll be fine 99.9% of the time. The physics of water freezing in pools really indicates that most areas with annually open pools don't need to worry too much about it as long as minimal precautions are taken.
Pentair automation (il)logic is predicated on a few hard coded absolutes and one of those is - the circuit with fastest speed WINS! The automation allows you to run as many feature circuits and relay circuits active as possible. Essentially think of it as all circuits can be run simultaneously. So, in the case of multiple circuits running, say for example, POOL Mode is active and my custom programmed SPILLOVER feature circuit is active, how does the automation know what to set the IntelliFlo pump speed at ? It just picks the the highest speed. So, if you had FREEZE PROTECT enabled on your BUBBLER feature AND you left it enabled on POOL as well, then it will run the pump at whatever speed is fastest. The IntelliFlo also has it's own internal settings that will run freeze protect when it is in stand-alone mode but if your IF is hooked up to an EasyTouch automation panel, those settings are overriden by whatever is programmed into the ET panel ... or at least they should be.
