Snow and Ice Melting WiFi Control Description
The WarmlyYours SCW-120-15A Snow and Ice Melting WiFi Control is a flexible, user-friendly, and affordable control option for snow melting and roof and gutter deicing systems. This unit features a built-in 120V WiFi standard switch and can be used without a relay panel for projects with an amperage draw of 15 Amps or less. However, for projects with an amperage draw that is greater than 15 Amps, 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.
This WiFi enabled built-in switch opens a variety of possibilities for how you operate your snow melting system. The easy access switch can be used manually like a traditional on/off switch or you can operate it remotely with your smart device. This control is compatible with various home automation systems like Amazon Alexa, Google Assistant, Apple Home/Siri, Schlage, and SmartThings. Additionally, it can be tied to an If This Then That (IFTTT) account. The IFTTT service has a weather app which allows for the SCW-120-15A Snow and Ice Melting WiFi Control to turn the system on based on weather events.
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.
It can even be paired with various open-source/open-standard software to create a non-proprietary control solution.
Features:
- Can be controlled/programmed remotely with a smart device via the free 'My Leviton' app
- Sleek design means this control presents a streamlined appearance when installed
- Works with My Leviton, Amazon Alexa, Hey Google, Apple Home/Siri, Schlage, SmartThings, or IFTTT (no hub required)
- Can be used to control snow melting or roof and gutter deicing systems

GFEP is the National Electric Code (NEC) required protection for fixed outdoor deicing and snow-melting equipment, which may be accomplished by using circuit breakers equipped with ground-fault equipment protection (GFEP) of 30 mA. It is important to understand that this required equipment protection is NOT the same as a 5 mA GFCI used for personal protection.
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.
