SunTouch DS-2C Rain & Snow Sensor Controller Automatic Snow and Ice Detection Controller for ProMelt Systems The SunTouch DS-2C Rain and Snow Sensor Controller is a fully integrated automatic snow melting controller designed to detect precipitation and freezing conditions while activating electric or hydronic snow melting systems only when needed. With a built-in precipitation sensor and powerful 30A switching capacity, the DS-2C helps reduce energy usage while keeping driveways, walkways, ramps, and outdoor surfaces clear of snow and ice. Key Features: Automatic rain, snow, and ice detection 30A control capacity at 240VAC Field selectable 100-120VAC or 200-240VAC operation Built-in precipitation sensor Adjustable temperature activation settings Adjustable delay-off drying cycle Selectable low-temperature cutoff Manual override operation Replaceable precipitation sensor Compact high-performance design Easy wiring and installation Supports electric and hydronic snow melt systems Smart Automatic Operation The DS-2C automatically activates connected snow melting systems when moisture and freezing temperatures are detected. Once snowfall stops, the adjustable delay-off cycle keeps the system running long enough to dry the surface and help prevent re-freezing. This automatic operation helps improve safety while minimizing unnecessary energy consumption. Installation and Wiring The DS-2C controller includes pre-installed wiring pigtails for fast installation. The unit may be mounted directly to rigid 1/2 inch or 3/4 inch conduit or secured using the integrated mounting tabs. Voltage operation is field selectable for both 100-120VAC and 200-240VAC systems using internal jumper settings. Specifications: Dimensions: 4-3/4" x 7" x 2-3/4" Weight: 2 lb.
