A built-in temperature sensor automatically turns the AutoCirc1 pump on when the water temperature in the hot water supply line cools down to 85º F. This cool water in the hot water supply line is then pumped into the cold water line and back into the water heater. The AutoCirc1 pump turns off automatically when the hot water supply line to the faucet reaches 95º F, ensuring the instant availability of shower warm water with maximum temperature hot water only seconds behind. When the pump is automatically turned off by the built-in thermostat, an auto closure device prevents hot or cold water from mixing in either supply line. Hot water will also be instantly available at all other faucets in the supply line between the water heater and the faucet where the AutoCirc1 pump is installed.See less »
