Brand: K-Rain SKU: 3104W
Product Overview
The K-Rain 3104W PRO-LC is a fixed four-station, 110 VAC irrigation controller for residential and light-commercial landscapes. Its indoor/outdoor enclosure and power pigtail provide installation flexibility, while the large LCD and full-program display make it easier to review watering days, start times, active stations, and special programming from one screen.
The controller is Wi-Fi capable, but smartphone, tablet, or computer control requires the separately purchased K-Rain 3100-BRIDGE Wi-Fi module. Without that module, the 3104W operates as a conventional four-station controller from its front panel. The fixed station capacity cannot be expanded with plug-in zone modules.
PRO-LC features include rain and rain/freeze sensor compatibility, seasonal water-budget adjustment from 10% to 200%, a buried-valve locator, and a built-in level for enclosure installation. The 3104W is the four-station model; legacy metafield data listing eight zones was incorrect and has been replaced. Confirm the 110 VAC supply, local electrical requirements, sensor wiring, and BRIDGE-module needs before installation.

Why Buy the K-Rain 3104W from Big Frog Supply?
This page corrects the legacy eight-zone metafield and clearly explains that the BRIDGE module is separate, preventing customers from expecting built-in Wi-Fi or additional stations. Big Frog Supply also carries compatible K-Rain sensors, valves, and controller accessories for completing the four-zone installation.
