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.

Frequently Asked Questions

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.

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.

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.

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.

Our systems can handle low temperatures, but many controls come equipped with a Low-Temperature Lockout Feature. This feature prevents the system from running in very low temperatures. At very low temperatures it can become difficult for the system to effectively melt the snow. It is however possible to turn off this feature should you need the system to keep running during such low temperatures.
