The ETI CIT-1 snow sensor accurately detects falling or blowing snow as precipitation at temperatures below 38°F(3.3°C) for surface snow melting applications. The CIT-1 provides the industry's most versatile and cost effective automatic snow melting control when used with either an ETI APS-3B or APS-4 Control Panel. Reliability and sensitivity are key CIT-1 features as the solid state design and a rugged aluminum housing and epoxy potting ensure many years of trouble free service. while precision precipitation and temperature sensors ensure snow detection accuracy. Typical applications include controlling snow melting systems for sidewalks, doorways, stairs, loading docks, ramps for the physically challenged and parking garages. Low voltage operation, up to 2000' (609.6m) separation from the control panel, and non-critical extension wiring are just a few of the features making this possible.
