Timer Control Snow & Ice Melt Description
The WarmlyYours SCM-DUAL Snow and Ice Melting Timer Control is a simple, affordable option for snow melting, slab heating, and roof and gutter deicing systems. At120V operational voltage, this unit features a 12-hour, adjustable timer and a NEMA 1 enclosure with hinged cover.
The operation of this control couldn't be easier as the user can simply turn the timer to their desired heating duration. It includes a 2-pole relay and terminal block for easy wiring. This control comes with integrated removable knockouts (4 on each side) so that you can run conduits through them without having to cut the metal box.
For projects with a smaller amperage draw (20 Amps for 120V or 10 Amps for 240 - 277V), the SCM-DUAL can be used without a relay panel. However, for projects with larger amperage draws, the controller must be used with a compatible relay panel. Using a relay panel, sold separately, allows control of larger jobs and can help switch voltages ranging from 120V to 277V.

Customer Questions & Answers
Timer Control Snow & Ice Melt has 26 Questions and Answers.
How quickly do these systems melt the snow?
That depends on a number of variables (like the temperature outside) but generally speaking these snow melting systems are designed to melt 1" - 3" of snow per hour. Anything above 3" per hour is typically considered blizzard conditions.
Is it okay to cut the snow melting 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.
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 WarmlyYours snow melt heating cable?
When installing outdoor WarmlyYours snow melting cables for your driveway, patio, walkway, terrace, stairs, ramp, etc. - 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 installation instructions and/or design layout plan to ensure the cable is installed with the correct spacing required for proper operation.
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.

Excellent support, product, documentation, and stock
Mitchell S., Richmond Hill, ON on 11/15/2023
I had many questions, both while planning, and just before installation. WarmlyYours was great and answers, their on-line documentation is detailed and helpful, and everything was in-stock for pick-up. Looking forward to the snow.
