Warmup WSM play online

Let the weather forecast activate your snow melting system. Warmups WSM-252W requires no sensors and automatically manages your snow melting system based on parameters set in the app.
- Pre-heating: only the WSM-252W can activate the system in anticipation of the snowfall. Typical sensor-based controllers are reactive and require too much wattage and amperage
- All in one: no more sensors or j-boxes. The WSM-252W is 12x12x6 with everything built-in
