A properly chosen controller turns a heating cable into a safe, efficient ice-management system. The easy heat rs 2 automatic roof de icing cable control is designed to do exactly that: it monitors the roof edge and activates only when conditions will actually melt ice (cold temperatures plus moisture), avoiding needless energy use while reliably preventing ice dams and gutter blockages. For homeowners, property managers and installers who want dependable performance without manual intervention, a focused controller is the single most important component in any roof de-icing installation.
The easy heat rs 2 automatic roof de icing cable control uses a simple, robust decision rule: it energizes the heating cable only when both cold temperatures and roof runoff (moisture) are detected at the sensor wire. This two-condition approach prevents the heating cable from running during harmless cold dry weather and limits operation to actual thawing events — the moments when you need heat to prevent ice formation. The controller’s logic and sensor make the system intuitive to operate and simple to commission for most residential roofs.
When evaluating the easy heat rs 2 automatic roof de icing cable control, installers and buyers focus on a few measurable attributes:
Rated load: the controller is commonly specified for 1200 watts at 120 VAC for a single cable run, which suits most residential ADKS-type heating cables.
Activation thresholds: the unit typically trips on when roof conditions fall around 38°F (3°C) and turns off near 48°F (9°C), though installers should confirm local settings and sensor placement for best performance.
Weatherproofing: the RS-2 is supplied in a weather-resistant enclosure suitable for outdoor near-roof mounting, and it comes pre-assembled for quick wiring.
These concrete numbers are what make selection and planning straightforward: you can size breakers and choose heating cable runs with confidence once the controller rating is known. (keyword appears in the section above.)

Installing the easy heat rs 2 automatic roof de icing cable control reduces manual labor and risk. Instead of climbing onto a cold, icy roof to chip ice or duct-tape temporary solutions, the controller automates protection and minimizes operator exposure to hazards. Because the RS-2 only runs when melting is possible, the system uses far less energy than a controller that simply times operation or stays on whenever a snowstorm arrives. That combination of smarter run logic and automated operation is what professional installers emphasize to homeowners that want both performance and lower winter energy bills.
A practical de-icing system starts with two matched parts: reliable heating cable and the controller. The easy heat rs 2 automatic roof de icing cable control is commonly paired with fixed-resistance ADKS cable or compatible 120 VAC PSR cables. For a typical residential eave and gutter run the 1200 W capacity covers most single-zone installations; for larger or multiple zones run separate controllers or split loads as the installation manual recommends. Using the wrong pairings can overload the controller, so always calculate cable wattage per linear foot and verify against the RS-2 rating before committing to a design. Manufacturer datasheets and retailer specs make this calculation simple.
Correct sensor placement and clean wiring are the most common reasons installations perform well:
Sensor routing: the sensor wire should be placed where meltwater first appears — typically along the roof edge and into the gutter — so the RS-2 senses runoff rather than standing snow. Proper placement ensures activation precisely when ice-forming conditions exist.
Electrical considerations: the controller must be fed from a dedicated circuit sized for the load and local code. The RS-2 includes a lighted plug to show incoming power and a visible indicator when the unit is calling for heat.
Weatherproof mounting: secure the unit near the roofline in a location that avoids direct snow burial and allows easy access for periodic inspection.
Following these practices reduces nuisance trips and ensures the easy heat rs 2 automatic roof de icing cable control responds only under the intended conditions.
Installers sometimes make the following errors; watch for them and correct before energizing the system:
Placing the sensor where snow accumulates rather than where meltwater flows — this causes false negatives or late activation.
Under-sizing the circuit or combining too many cable runs on a single RS-2 beyond the rated 1200 W capacity.
Routing the heating cable and sensor where they are exposed to mechanical damage (sharp metal edges, frequent foot traffic on the roof) — protect them with clips and grommets.
Correct these common issues and the easy heat rs 2 automatic roof de icing cable control will deliver reliable performance season after season.
Many homeowners with moderate electrical skill can install an easy heat rs 2 automatic roof de icing cable control following the manufacturer’s instructions and local code. The unit ships pre-assembled with clear wiring labels, and multiple retailers publish installation PDFs and videos that demonstrate the key steps.
However, for rooftop work, circuit sizing, and code compliance, professional installation is often the safer and faster option. Electricians and experienced roofers ensure sensor placement, junction routing and grounding meet local requirements and that the controller integrates with GFCI or other mandated safety devices.
Once installed, the easy heat rs 2 automatic roof de icing cable control requires minimal maintenance: visually inspect the sensor and cable for debris or damage before the first hard freeze, confirm the power indicator and activation light function, and make sure mounting hardware is secure after storms. Periodic checks before and during winter keep the system reliable and extend component life. If the unit shows unexpected behavior, the instruction sheet includes simple troubleshooting steps and test procedures.
Homeowners with long roof runs, multiple gable ends, or complex roof geometry may prefer a zoned approach: multiple easy heat rs 2 automatic roof de icing cable control units controlling dedicated heater runs, or a higher-capacity commercial controller for large systems. Zoned controllers reduce cabling complexity and prevent a single failure from disabling the entire roof protection system. Talk to your installer about the best approach for your roof plan and energy objectives.
The RS-2 controller is widely stocked by major retailers and part suppliers; compare shipping, return policies and warranty coverage when purchasing the easy heat rs 2 automatic roof de icing cable control. Retailers often publish compatibility notes and downloadable manuals; a supplier that provides clear installation documents and phone support will make commissioning easier and reduce the chance of costly callbacks.
For many residential roofs the easy heat rs 2 automatic roof de icing cable control offers an elegant balance of automation, energy savings and straightforward installation. To get the best results: size your heating cable runs to the RS-2’s rated capacity, place the sensor where run-off appears, follow the manufacturer’s wiring diagram, and run a quick functional test before the first cold spell. Do that and your de-icing system will protect gutters and eaves with minimal intervention while keeping energy use in check
