Auto Top off Controller

[steamman]

Not really a DIY project except that you have to do a little wiring yourself. It doesn't come with float switches. Deeter Electronics makes a great controller. I bought one of these years ago. Still going strong. I am going to buy another and just wanted to share this great controller. They make two models. A two float and a three float.

I just ordered this optical sensor from Amazon for $22. It didn't come with a wiring diagram. I believe L and N are Hot and Neutral. Would anyone like to advise as to how to hook up the pump wires? I think the other four terminals are NO and NC. But why have two sensors?

Easy enough to power it up and just test the terminals with the sensor in and out of the water. I answered my own question.




Descriptions:

When the level status LED (D3, D4) on the module are working.

This product is for liquid level sensing, convenient to get aware of liquid level and easy to adjust.

Easy to install and easy to use.

Anti-static packaging.

I am stumped. I power L and N. I have continuity between the first two terminals and the second two terminals powered or not. I do not have continuity between terminal one and three or one and four or two and three or two and four. Keep in mind this is all not powered.

If I power the board there is no change to terminal continuity. If I drop one sensor in the water in a time I get no change in continuity and no power across any two terminals. Same if I take the first sensor out and drop the other sensor in the water.

If I put both sensors in the water I get continuity across all terminals although still no power.
