This Time Control with Freeze Protection is designed to automatically control as well as protect the Pool/Spa equipment and plumbing against freeze damage. The Control, if wired according to instructions, turns ON/OFF the Filter Pump on a daily schedule and also turns ON the Filter Pump when the air temperature (where this Control is located) drops below the temperature set by the thermostat dial (between 33°F and 42°F). Nevertheless, the Control is not intended to be a substitute for insulation, coverings or maintenance.
