The Underhill Sapien 2-Wire Controller Handles up to 63 Stations

Underhill International says its Sapien product represents the industry’s first dedicated two-wire irrigation controller that operates up to 63 stations.

Two-wire technology allows the installation of an entire irrigation control system with just two wires (power and signal) running from the controller to a decoder/receiver in each valve. Decoders respond to “on-off commands” from the controller. Known as a “decoder-based” controller, the Sapien 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 can be installed anywhere, including 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 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 also available.
