The HSC–4 Pavement-Mounted Deicing Controller reliably operates snow and ice melting heaters based upon pavement condition. This ensures that deicing heaters operate only while needed which minimizes energy costs without sacrificing snow melting effectiveness.

The HSC–4 signals for snow and ice melting at pavement temperatures below 38° F (3.3° C) while moisture in any form — including water, snow, sleet or ice — is present. Once the moisture element has dried, the built-in, one hour hold-on timer keeps heaters operating to help ensure complete snow and ice melting.

The HSC–4 accurately measures pavement temperature by compensating for its internal heating. This eliminates the cost and complexity of a separate pavement temperature sensor. For improved efficiency, products mount close to the deicing heaters to ensure that pavement and sensor become dry at about the same time.

The new mounting system provides accurate alignment with the pavement surface. Six available conduit locations add to installation flexibility and simplicity. The sensor subassembly is field replaceable without disturbing the pavement. The HSC–4 is an NEC Class 2 device operating from customer supplied 24 volts AC. It provides a floating Form A low voltage 2 amp relay contact for interfacing external heater control contactors.

Only brass, epoxy, and stainless steel are exposed to the pavement surface. Precision machining gives these products a handsome appearance that will please the building owner, engineer, and architect.

LIMITED WARRANTY - ETI's two year limited warranty covering defects in workmanship and materials applies. Contact Customer Service for complete warranty information.
