We sell basic and reliable water level controllers using high quality magnetic reed float switches. We've found float switches to be more reliable than other styles of ATO sensors. You'll need a reservoir, pump and some tubing to complete your ATO system. Mount the float switch at your desired water level, plug your pump into the ATO and it will power your pump when your water level is low to refill your tank. Power switching is done with a 10 amp double pole relay wired using both sets of contacts which reduces contact wear and provides you an additional switch for redundancy. 2 year warranty! You can also reverse a float for run-dry protection, etc. by removing the clip that secures the float and re-install the float with the magnets inside oriented down. This makes the controller powered when that float is up (normal operation is powered when the float is down and power is off when the float is up). Please read the FAQ. Email: AutoTopOff@gmail.com
