Review: Works quite well, just one thing to be aware of.... - This is actually a pretty solid unit. Works really well. There were a few things I wish I had known before I bought it. *** WATER LEADS ARE 12V NOT 24V *** I thought because the switch operates on 24V that the leads would be 24V too but they are not, they are 12V. This required me to purchase different contactless water level sensors that supported 12v instead. I was trying to use contactless because I didn't want to deal with long-term corrosion of the leads in the water (ya, they are stainless steal but I'd prefer contactless anyways). *** WATER LEADS ARE AC NOT DC *** This one surprised me at first. The output of the leads that go into the water is AC. I discovered this because I had originally tried to use those contactless sensors I found on desertcart that allow me to place the water level sensor on the outside. Those little contactless sensors also worked great but they would output DC voltage. I was puzzled why the switch didn't trigger when it was getting the 12v it was expecting. It wasn't until I hooked the switch up to my oscilloscope did I see that the 12v being used for the water leads was AC, not DC. Turns out, AC conducts much better in water than DC so it makes sense to use AC instead. As a result, those contactless switches dont work. However, if you use the leads that are supplied, they should work for many years and I expect this to be a solid unit.
Review: Good so far. - 04/2025 update: It no longer senses the high level causing overflow (very bad if you don't have an alarm). probes have rusted in just 5 months Nowhere it mentions the probes can't touch each other to work, took me a while to figure it out because I attached the to an acrylic bar vertically (water level). Will have to "dangle" them using a horizontal bar. :( I see a lot of reviews about not lasting too long, let's see.

## Questions & Answers

**Q: Can you extend the probe leads?**
A: I would think so.  Just cut and extend.

**Q: What kind of sensors is are these, can they be replaced with floats?**
A: Dear customer,because we consider that the fuel may stick to the stainless steel, thus affecting the detection of the controller.And it can't be replaced with the floats.Thank you for consulation.

**Q: How far can the sensors be away from the controller?  In my case - The control room is about 150 feet away from the fountain.**
A: Extend the wire yourself.

**Q: I have no electricity socket near my water source. How would I connect this to a battery? Is it possible?**
A: Dear customer,our controller can't be used by the battery.It need to be connect with the power for 110v,220v,12v or 24v. Unless the battery is the above voltage.If you have any questions about the product,please contact us.

### ⭐⭐⭐⭐⭐ Works well and easy to use and setup
*by A***M on July 28, 2023*

Works well and easy to use and setup. Saved this old water boiler ($2,000+ to replace a new one) that has a chipset that's no longer made. The water boiler would overfill and won't stop filling as its original chip set solenoid failed. Bypass the original chipsets fill portion and hooked the water boilers water level probe to the Roamoris Sump Pump Switch Control Automatic Water Level Controller Supply, gave it110v after switch and circuit breaker. Problem fixed. Looks fairly solid and well made. We will see how long this last, if it fails I'll post a new update.
