Advanced Snow & Ice Melt Control Description
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. The SCA-DUAL is cULus listed. Additionally, it has a maximum 2 sensor capability and can be used with aerial, gutter, or pavement sensors.

Customer Questions & Answers
Advanced Snow & Ice Melt Control has 26 Questions and Answers.
Is it okay to cut the heating cable if it is too long for the application for which it was designed?
Never cut the heating cable. A heating cable will not work if it has been cut. If the heating cable is too long, call WarmlyYours to consult with a technician who will guide you in utilizing the additional length of cable.
Does the factory splice need to be completely embedded during installation?
Yes. The manufacturer's splice that connects the heating element to the cold lead should be entirely embedded in a noncombustible material (like asphalt, concrete, or mortar) within the outdoor surface that is being heated.
How does the electric snow melting system compare to hot water tubing (hydronic) systems?
The material costs are similar. However, electric systems are easier to install, with fewer components and significantly lower maintenance costs. Electric systems will run for a shorter period of time to give the same level of performance but with much higher energy efficiency (typically 95%-98% efficient). Controls and sensors required for the two types of systems are very similar. Electric systems do not usually require slab insulation and do not create the concerns typically associated with hydronic systems. These concerns include, but are not limited to, return temperatures, flue gas venting, waterway shrinkage and property damage caused by leaking pipes or tubes.
May I cross or overlap the heating cable?
Never cross, overlap, or allow the heating cables to touch each other. Doing so will quickly cause a circuit failure due to excessive heat build up. Always follow the product instructions and/or design layout plan to ensure the cable is installed with the correct spacing required for proper operation.
How much does a snow melting system cost?
A snow melting system typically costs between $8.00 and $20.00 per square foot. However, you'll also want to keep in mind the cost of a control, and if required, sensor/s for your snow melting system, which will add to the cost.

There is definitely a learning curve but after that it was great to see the finished product working. Customer was extremely happy.
Your online and telephone support system is the greatest!
Bonnie P., Sterling, AK on 10/17/2021
We just finished laying in the wire and poured our cement, just a day before it started snowing-so we are curing the cement as I type. The men are now hooking up the electrical inside portions. The instructions have been so easy to follow step by step. I wanted to let you know it was so easy, I decided to do the one side of my garage with both systems to have a longer driveway of warmth/snow melt...because it was so cost effective that our family man-power did the labor. I plan on contacting you next Spring after the thaw to order up more wire, etc to do the smaller 14 foot section, which will be turned into a bedroom with a big front window I hope to enjoy looking out during the winter, instead of looking at by past 6 foot snow falling off my roof and building a wall I can't see through. I will send the end result after the electrical is finished plus a photo. :):)
Excellent Customer Service and Support
Richard L., Budd Lake, NJ on 02/15/2021
Working with WarmlyYours was great. The Customer Service Agent was knowledgeable, responsive and pleasant. All my questions were clearly answered promptly by the Technical Support Team. I would highly recommend this company for all of your floor and outdoor heating projects! Thank you
Installed myself, works great!
Michael S., Ellicott City, MD on 02/15/2021
I purchased a Transfer Switch box (12 x 120 volt), a snow sensor, and an ice sensor, and installed them myself as per instructions. I had a couple questions (how to connect two "yellow wires" and where to best position the snow sensor), both answered immediately by a quick phone call. I couldn't be happier.
