JBJ ATO issue

All LED lights are on. I guess floating fail sensor kicks in that's why it hasn't overflow.

Something doesn't make sense with that. If you have the switch set to mode A and sensor 1 is in your sump and 2 is in your reservoir then there shouldn't be a situation where all the LEDs are on. Sensor two should only light up if the reservior level drops and then it should shut off the pump. So if sensor two is on the pump should be off.

Is the switch set for mode A?
