Sapien, a dedicated two-wire controller that operates up to 63 stations, is now available from Underhill International, the company that pioneered two-wire technology in the U.S.


Two-wire allows the contractor to install an entire control system with just two wires (power and signal) running from the controller to decoder/receivers in each valve. The decoders respond to “on-off commands” from the controller.


Sapien, known as a “decoder-based” controller, also uses the same valve decoders that are installed in a Hunter ICC two-wire system and in Underhill’s Universal 2Wire modules.


Designed for flexibility, Sapien works in multiple applications: new irrigation systems, a multi-wire conversion or a two-wire (or multi-wire) expansion. No special wiring or field grounding is required.


With an easy-to-read backlit display, Sapien’s features an exclusive LightTouch™ screen that “talks” the user through the set-up with buttons that light up sequentially.


Sapien offers ABCD and manual programs, seasonal adjust by percentage and 12 start times per day. It is radio-control ready and rain/wind/frost sensor compatible. The controller measures just 6.3” high x 7.33 “ wide x 1.78” deep. Stainless steel wall mounts, water-proof enclosures and pedestal models are available.


Two-wire systems are typically more cost effective than multi-wire because they require only two wire runs, saving installation time and materials.


Underhill has more than 150,000 decoders at work in the ground worldwide and has expanded two-wire use in the U.S. The technology has been popular in Europe for decades for residential and large commercial installations, including sports fields, parks and public areas.
