Intermatic Timer, 24-Hour Freeze Protection Control Spa Timer w/ Override
These Freeze Protection Controls are designed to protect the pool and spa equipment and plumbing against freeze damage. They turn ON the pump and the heater when the outdoor temperature drops below the temperature set by the user adjustable thermostat. Models without timer connect to a timing or switching device and together, they control operation of the equipment as well as protect it against freeze damage. Models with timer provide both automation and protection for the equipment.
