I am using the controller mainly for auto top-off. When I was setting my tank, my bigger concern was over filling. My setup have 3 float switches in the sump and 1 in the tank. In the sump, 1 for top-off, 1 for low level, and 1 for high level. If the top-off switch doesn't stop the fill, the high level will. If sump water is low, turn off the return pump before pump goes poof. In the tank, if your overflow is plugged up, float switch will turn off the return pump. I programmed to have 30mins delay, then the top-off pump turn on. I use aqualifter pump for top-off because I want a slow top-off and if something wrong will the pump, the worse case is no top-off. Unlike using solenoid valve, if the valve stuck open, you know what happen.....
And of course individual output should be fused. You can do so much will that little thing. Have fun with it!
Is that a AC input or DC input?
