Housing for Pavement Snow and Ice Sensor (Housing Only)

Part Number: SC-SS-PAV-HS
Snow melting sensors tell your control when to run. Aerial sensors read air temperature and precipitation above the surface; pavement and slab-mounted sensors read moisture and temperature in the slab itself. Identify your model below for its installation manual, wiring diagram, ohm values and specifications.

What is the wire spacing for snow melt cables?

The most common spacing for snow melting systems is 3“ from wire to wire. However, we can design snow melting systems based on your local climate and weather expectations that might have different cable spacings to ensure the most efficient system possible. We also offer snow melting mats with 3" and 4" spacing.

Where does the aerial sensor get placed?

In an area free of obstruction and able to detect rain or snow, yet low enough so that it is easily accessible if service is needed. Atop a fence post or on an 'L' bracket on the side of a building are common.

How should the Cold Lead be installed for patios/walkways/driveways?

The electrician must route the cold lead(s) through rigid metal conduit(s) or other approved means, to get back to an accessible weatherproof junction box(s). Care must be taken by the electrician so that none of the heated section of Cable enters the conduit(s).

Why isn't a temperature sensor required for all installations?

It depends on how the system is intended to operate. If the expectation is manual operation (ex. WiFi or Timer Control), then no sensors are required. If the expectation is automatic operation, then the system will require at least one snow sensor.

At what depth do the snow melt cables need to be?

Minimum is 1.5“ and Maximum is 2.5“

Does the mat require a sensor to go with it?

No, a sensor is not required with the snow melt system. However, certain automatic controllers require a temperature/moisture sensor to sense atmospheric conditions and may also require an in-slab, high temperature limit sensor to be installed (notably, asphalt installations).

The neutral on GFEP/GEFP/RCCB 240V breakers is not used, why do I need this then?

A 2 pole single-phase 240V circuit works by continuously monitoring the current flowing through both hot wires of the circuit. If it detects even a slight imbalance between the current on each hot wire (indicating a ground fault), it will quickly trip, cutting off power to the circuit. Essentially, it compares each leg of the 240V circuit and trips if they are not precisely equal.

What is the purpose of the Low Temperature Lockout Feature on certain snow melt controllers?

This feature prevents the snow melting system from running, by default, in temperatures below 17°F (–8.33°C), or as set by the user. At temperatures this low, it becomes difficult for the system to effectively melt the snow. It is, however, possible to turn off this feature should the system be required to keep running during these low temperatures.

What are the best home features for cold climates?

The best home features for cold climates include a simple gable roof to shed snow, covered entrances for protection, airtight triple-pane windows to prevent heat loss, and radiant heating systems. These features work together to maintain interior warmth, reduce energy bills by up to 25%, and ensure structural safety during harsh winters.
