Overview

WiFi Snow Melting Controller System for Roof, Gutter, Driveway, and Walkway De-Icing

The YeloDeer EFC1 is an automatic snow melting controller designed to operate compatible heating cable systems based on both outdoor temperature and moisture conditions. Choose the Ground Sensor Kit for paved surfaces or the Roof Sensor Kit for roof and gutter de-icing applications.

The controller supports 120V and 240V systems, WiFi monitoring through the Smart Life app, and automatic or forced heating control. The heating cable itself provides the snow-melting heat and is not included with the controller sensor kits.

Quick Fit Snapshot

Ground or Roof Sensor Choose EFS-G for driveways and paved surfaces, or EFS-R for roofs, gutters, and downspouts.

120V / 240V Compatible EFC1 accepts 85–265V AC, 50/60Hz power for compatible North American snow melting systems.

16A Max Relay Maximum controller relay current is 16A. For continuous operation, keeping the connected load at or below 11A is recommended.

Temperature + Moisture Automatic heating operates only when the selected temperature conditions and moisture detection requirements are both satisfied.

Key Benefits

Automatic Snow & Ice Control Helps operate compatible heating cables only when cold and wet conditions indicate de-icing may be needed.

Application-Specific Sensors Separate ground and roof sensor designs allow the system to match the way meltwater is detected in different locations.

WiFi Remote Monitoring Connect through a 2.4 GHz WiFi network and the Smart Life app for compatible remote monitoring and control functions.

Automatic or Forced Heating Use automatic dual-sensor operation for normal winter control or activate forced heating when temporary manual operation is required.

Installation

Installation Overview

The EFC1 is a DIN-rail electrical controller and must be installed and wired by a qualified electrician. The following information is intended as a pre-installation overview rather than a replacement for the complete instruction manual.

Select the correct EFS-G Ground Sensor or EFS-R Roof Sensor kit for the application.
Confirm supply voltage, heating cable voltage, total current, circuit protection, and whether an external contactor is required.
Install the EFC1 indoors or inside a suitable weatherproof electrical enclosure.
Install the air temperature sensor outdoors in a shaded location away from direct sunlight, rain, and snow.
Install the selected moisture sensor where representative meltwater can reach the sensor surface.
Complete power, load, grounding, and sensor wiring according to the wiring diagram in the instruction manual.
Restore power, configure the operating temperature range and moisture settings, and test system operation before winter use.

Controller Installation

DIN Rail Mounting Mount the EFC1 on a standard 35 mm DIN rail.

Protect the Controller The EFC1 is IP20 and must be installed indoors or inside a suitable weatherproof electrical enclosure.

Mount Above Ground The manual specifies installing the controller more than 19.7 in / 0.5 m above ground.

Recommended Installation Temperature Install in an environment approximately 23–95°F / -5–35°C when possible.

Add Circuit Protection Install appropriate circuit breaker and leakage/GFCI protection in series with the controller.

Ground the Heating System The heating cable ground conductor must be connected to the mains grounding system.

Air Temperature Sensor Placement

Recommended Install the air temperature sensor in a shaded outdoor location protected from direct sunlight, rain, and snow. Under the eaves is recommended when available.

Avoid Do not route the air sensor cable alongside power wiring unless appropriate shielding is used, because electrical interference can affect temperature readings.

EFS-G Ground Sensor Installation

Install Horizontally The moisture sensor must be placed horizontally with its sensing surface facing upward, even when the surrounding paved area is sloped.

Keep the Top Flush Install on a solid concrete base with the sensor surface flush with the finished ground surface.

Position Between Heating Cables Keep the sensor at least 0.8 in / 2 cm away from each adjacent heating cable.

Stay Away From the Edge Keep the sensor at least approximately 3.3 ft / 1 m from the edge of the snow melting area.

Choose a Representative Wet Area Install in a low, wet, shaded area where meltwater conditions represent the snow melting surface.

Seal Around the Sensor Seal gaps so meltwater flows over the sensing surface rather than draining into gaps around the sensor.

For asphalt installations, replace the normal protective conduit with metal conduit and do not install the EFS-G sensor before paving. Protect sensor wiring and follow the complete installation instructions.

EFS-R Roof Sensor Placement

Install the EFS-R in a roof, gutter, or drainage location where melting snow or ice water can reliably reach the moisture-sensing surface. Keep the sensor secured, unobstructed, and accessible for seasonal inspection and cleaning.

Load Wiring

The EFC1 LOAD terminals function as switching contacts and do not independently supply power to the heating cable.

Follow the 120V or 240V wiring diagram supplied with the controller. For loads above 16A, 3-phase systems, or supply voltages above 265V, use a properly rated external AC contactor.

WiFi Installation Notes

2.4 GHz WiFi Only The controller requires a stable 2.4 GHz WiFi network for Smart Life app connectivity.

Check Signal Before Final Mounting Confirm WiFi performance at the controller location before completing the enclosure installation.

Prefer Non-Metallic Enclosures A plastic or other non-metallic enclosure is recommended when possible for more reliable WiFi communication.

Avoid Fully Enclosed Metal Boxes A metal enclosure may weaken or block WiFi. Verify signal strength before final installation if a metal enclosure must be used.

FAQ

Which SKU should I choose?

Choose the EFC1 + EFS-G Ground Sensor Kit for driveways, walkways, sidewalks, porches, ramps, loading docks, and similar paved snow melting surfaces.

Choose the EFC1 + EFS-R Roof Sensor Kit for roof edges, gutters, downspouts, and roof drainage de-icing systems.

Choose the Weatherproof Enclosure only when you need an enclosure for the controller. The enclosure SKU does not include the EFC1 controller or moisture sensor.

What is the difference between the EFS-G and EFS-R sensors?

Both work with the same EFC1 controller and use moisture detection with an internal 5W sensor heater.

The EFS-G is a round ground sensor designed for horizontal, flush installation in paved snow melting surfaces. The EFS-R is a lower-profile roof sensor designed for roof, gutter, and downspout applications.

Does the controller detect snow directly?

No. The system detects water on the moisture sensor surface rather than snow itself.

Because snow and ice are poor electrical conductors, the moisture sensor uses its built-in heater to help melt snow or ice on the sensing surface. Once water is detected and the outdoor temperature is within the selected operating range, automatic heating can begin.

Why might the system not start immediately when snowfall begins?

The sensor may need time to melt snow or ice on its surface into detectable water. This is normal for the moisture-detection method used by the system.

The controller also operates only when the outdoor temperature is within the configured operating range.

Can I use the EFC1 with both 120V and 240V snow melting systems?

Yes. The EFC1 accepts 85–265V AC, 50/60Hz input and can be wired for compatible 120V or 240V systems.

Always confirm the heating cable voltage, circuit configuration, wiring method, grounding, and load before installation.

Can the controller power my heating cable directly?

The controller relay is rated for a maximum of 16A. For long-term continuous operation, keeping the direct connected load at or below 11A is recommended.

For loads above 16A, 3-phase systems, or systems above 265V, the EFC1 should control a properly rated external AC contactor rather than carry the full heating load.

Can the EFC1 controller be installed outdoors?

The EFC1 controller itself is rated IP20 and should not be directly exposed to outdoor weather.

Install it indoors or inside a suitable weatherproof electrical enclosure. For WiFi installations, a non-metallic enclosure is preferred when possible because metal can reduce WiFi signal strength.

What WiFi network does the controller require?

The EFC1 uses a 2.4 GHz WiFi network and supports remote control through the Smart Life app.

Check WiFi signal strength at the final installation location before completing the enclosure installation.

Guides

How Automatic Mode Works

1. Monitor Outdoor Temperature The controller continuously checks outdoor air temperature.

2. Monitor Moisture When temperature enters the selected operating range, the system begins monitoring the moisture sensor.

3. Start Heating When water is detected while temperature conditions are satisfied, the controller activates the connected heating system.

4. Continue Through Drying Delay After moisture is no longer detected, heating continues for the preset drying-delay period before shutting off automatically.

Temperature Range Logic

Above Upper Limit Conditions are considered too warm for normal snow or ice risk, so moisture monitoring does not operate.

Between Upper & Lower Limits The system monitors moisture and can activate heating when water is detected.

Below Lower Limit The controller stops automatic moisture monitoring because conditions may be too cold for effective melting or drainage.

Example from the manual: with an upper limit of 41°F / 5°C and a lower limit of 14°F / -10°C, moisture monitoring operates while outdoor temperature is between those limits.

Forced Heating Mode

Forced Heating Mode allows the connected heating system to operate continuously for a selected period without checking the normal temperature and moisture activation conditions.

Typical Uses

Emergency De-Icing System Testing Pre-Heating Drying Wet Surfaces

Forced Heating bypasses the normal automatic detection logic. Use it only when necessary and monitor the connected heating system appropriately.

Before Each Winter Season

Inspect All Wiring Connections Inspect Heating Cable for Visible Damage Check GFCI / Leakage Protection Clean the Moisture Sensor Surface Remove Leaves, Stones, Dirt, and Debris Confirm Meltwater Can Drain Away Check Sensor Placement Run a Short Test Before the First Snowfall

Sensor Care

Keep the Surface Clean Leaves, dirt, stones, ice blockage, or other debris can interfere with moisture detection and may trigger abnormal-operation alarms.

Maintain Drainage Water must be able to reach and leave the sensing surface normally. Standing water or poor drainage can affect system operation.

Inspect After Severe Weather Check the sensor and surrounding area after heavy snowfall, ice accumulation, maintenance work, or unusual drainage conditions.

Check Before Replacing Parts If abnormal moisture detection occurs, first inspect sensor cleanliness, drainage, wiring, and physical condition.
