What is a freeze guard?

A freeze guard is a temperature sensor that overrides the pool timer. Most freeze guards are set at a temperature of 38 degrees. If the pool timer is off and a cold front moves in, the freeze guard will override the timer and turn on the pool pump. Once the pool is circulating (moving water at proper pressure) it will usually prevent the water from freezing. A freeze guard is not a heater.
