Underhill 2Wire Decoder Irrigation Control Systems for Any Controller

Underhill™ 2WIRE irrigation control systems, featuring decoder technology with over 100,000 field successes, offer proven reliability and increased versatility over traditional in-field satellite control.

On projects with over 300 feet (91 m) of mainlines, you will also enjoy dramatic savings in time and money. Using only two wires to control just 3 or even 63 zones, the reduced costs in wiring alone makes 2WIRE a much smarter solution than multi-wire installations. But the savings don’t stop there. System expansions are easy...simply splice into the control line and add decoders. Repairs are a simple matter as well, with only two wires to reconnect. Compare that to fixing a break in a line with 40 or 50 control wires.

Our decoders use leading edge technology for superior performance and are built tough. In fact, the 2-year warranty that accompanies Underhill™2Wire decoders includes lightning protection - even against direct hits. 2 cool.

Underhill™ 2WIRE Decoder. 2 simple. 2 smart. 2 bad for everyone paying a lot more for a multi-wire mess.
