The ETI HSC-4 Pavement Mounted Snow and Ice Melting Controller is designed to energize snow and ice melting heaters based on the pavement conditions. The controller will turn on deicing heaters when the pavement temperature falls below 38F (3.3C) while water, snow, or ice is present.
NEC Class 2 device operating from customer supplied 24VAC
Form A low voltage 1 amp relay contact output for interfacing with external relays, valves, pumps, and energy management systems
1 hour hold-on timer
Reliable snow melting
Minimum energy costs
Control based upon pavement conditions
New mounting system provides accurate alignment with the pavement surface
The location of the sensor should be 1). Centered between runs of hydronic tubing or heater
Cable and 2). Exposed to precipitation and pedestrian or vehicular traffic.
Install the sensor housing on a firm, smooth surface such as a precast patio block or similar masonry module. Care should be exercised in adjusting the final grade and level of the sensor to ensure that the sensor surface will be flush with the finished pavement, and that the adjacent pavement be either level or slightly crowned. A sensor submerged in puddled water will not function properly.
