The WarmlyYours SCW-120 Snow and Ice Melting Wi-Fi Control is a simple, affordable option for snow melting and roof and gutter deicing systems, the company says. At 120 VAC operational voltage, this unit features a built-in WiFi switch. The Snow and Ice Melting WiFi Control is appropriate for use with relay panels. This WiFi enabled built-in switch can be used manually like a traditional on/off switch or it can operate it remotely with a smart device. Additionally, this control can be partnered with various home automation systems like Amazon’s Alexa or Google Assistant to energize the snow melting system based on weather information. WarmlyYours.
