Hello, it is unfortunate you are not pleased with the Eaton sensors. Please note the sensors do come in two varieties, Occupancy--OS310U and vacancy---VS310U. Now on the OS310U it is AUTO ON and AUTO OFF. Vacancy sensors are MANUAL ON and AUTO OFF. The instruction sheet we send with the units works for both unit, but does state which options work with what sensor. Now the sensor shown is our Vacancy sensor which is Manual on and Auto off. Thank you
