Just set up JBJ ATO. Using the recommended method from JBJ. 2 sensors. Mode A. Sensor1 in sump sensor 2 in reservoir tank. Water evaporated nothing happened. I switched the sensors around. Sensor 1 to reservoir tank, sensor 2 to sump. Pump turned on and added water. I got scared and thought it might overflow my sump so I pulled the plug on the pump. Afraid to go to work tomorrow and leave this setup. PLEASE HELP.......
