The HLC-1e by Custom Automated Products protects your garden from
overheating. The HLC-1e constantly monitors your garden temperature. If
the garden exceeds the temperature that you have set, the HLC-1e turns
off your lights so that crop damage will not occur. It then turns on
the Temp Exceeded" light to let you know that an overheating situation occurred. When the temperature returns to normal, it will turn your
lights back on. It comes with a 15' remote temperature sensor. The
HLC-1e is rated at 15 amps @ 120 volts. 3 year warranty.
