Freeze Control
Model PF1102 Freeze Protection Control is self-contained in an indoor-outdoor, beige, rainproof enclosure and designed to be connected to a timing or switching device. Together, they control as well as protect the Pool/Spa equipment and plumbing against freeze damage. The Control, if wired according to instructions, turns ON the Filter Pump when the air temperature (where this Control is located) drops below the temperature set by the thermostat dial (between 32°F and 45°F). Nevertheless, the Control is not intended to be a substitute for the insulation, coverings or maintenance.
