About the Advanced Roof & Gutter Control
The SCA-DUAL provides for advanced control of snow melting and roof and gutter deicing systems to minimize
operating costs. It operates electrically- and mechanically-held contactors for pilot duty applications. With automatic
and manual override operator controls, the SCA-DUAL includes an adjustable hold-on timer to continue heater
operation up to 8 hours after snow and ice accumulation stop to ensure complete melting.
Featuring a weather-resistant NEMA 4X enclosure, this unit handles resistive loads up to 30 amps and operates at
100 - 277 Vac and 50/60 Hz. C-UL-US Listed, the SCA-DUAL has a maximum 2 sensor capability and can be used
with the GTR-SS and/or AIR-SS sensors.
