Why does my A.T.O. automatically shut off after a few minutes of operation even though the water level has not reached the float sensor?

Why does my A.T.O. automatically shut off after a few minutes of operation even though the water level has not reached the float sensor?

All A.T.O. Controllers have a factory “Float Fail-Safe” duration time period of 3 minutes and 45 seconds of operation before power to the pump is turned off. The Pump LED will glow but power to the pump will not be turned on. This feature was designed to act as a safety mechanism in the unlikely event the float sensor(s) failed or if something was to get stuck in between the sensor(s). You will have to reset the float sensor(s) to restart the controller.
