Power Modulator Snow Melt Control Description

Featuring four contactors and a built-in ground fault sensor, the Power Modulator 3 allows customers to control one or multiple zones one at a time, thereby saving money and handling a higher amount of power than the average control. This electrical box enables customers to use one contactor per zone, up to four zones. This can be done in one of two ways. Either all four zones can be used for snow melting, or three zones can be used for snow melting and the fourth zone can be used for roof and gutter deicing.

Note: An upper limit temperature sensor is included. This sensor is installed under the surface and measures the ground temperature. This information is used to save energy during snow-melting operation.

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.
