About the Premium Snow Melt Control
The Premium snow melt control when used with compatible sensors automatically controls snow/ice melting heaters,
ensuring minimum operating costs. Typical applications include pavement, sidewalks and loading docks. The
adjustable hold-on timer continues heater operation for up to 10 hours after snow stops to ensure complete melting.
The optional Remote Control Unit can be located where system operation can be conveniently observed. The
calibrated 40°F to 90°F (4°C to 32°C) high limit thermostat prevents un-necessary activation when using constant
wattage heating cables or mats. It also permits safe testing at outdoor temperatures too high for continuous heater
operation. The High Limit Temperature Sensor is included. The SCP-120 provides a relay closure interface for use
with energy management computers (EMC). This feature can also be used for general purpose remote control and
annunciation and other advanced applications. All sensor and communications wiring is NEC Class 2. This simplifies
installation while enhancing fire and shock safety. The SCP-120 can interface up to six sensors (Aerial or Gutter
sensors) from the product family. Using more sensors provides superior performance by better matching the controller to site performance requirements. The SCP-120 is an exceptionally capable deicing controller.
