The Freeze Miser® operates like the thermostat in your home. After installation, it senses the internal water temperature arriving at the faucet, not the air temperature.The Freeze Miser® activates when the water temperature drops below 37º F/3º C. No water is released until the activation temperature is sensed. The Freeze Miser® is on guard 24/7!
