This is the first winter with our newly renovated pool. It has the Polaris EOS Command Center with the freeze guard set to come on at 36 degrees air temp. or 34 degrees water temp. When the freeze guard activates it turns the pool and booster pump on for 15 minutes, then shuts down, turns the valves, then runs the spa for 15 minutes, alternating back and forth until the temp gets above 36 degrees. The blower to the spa runs for 5 minutes every half hour. I don't want to take any chances on damaging my plumbing, pumps etc, but 36 seems too high for activating the freeze guard. Last winter my filter was prone to blowing the seal, and since we had decided to renovate, I did not run the pump at night, or when I was away. Several times the temp dropped to the mid 20's with no apparent damage. I want to be safe, but don't care to cycle my equipment on and off so much before the temperature really requires it. Our Texas winters are pretty mild, but temps may hang between 36 and 32 for long periods of time. What's the lowest temp I can safely go before activating the freeze guard? All opinions or personal experiences will be greatly appreciated.
