Tekmar 671 - WiFi Snow Melting Control, Pulse Width Modulation

The WiFi Snow Melting Control 671 operates hydronic and electric heating equipment designed to melt snow and/or ice from roads and walkways surfaces. The control works with tekmar Snow/Ice Sensor 090 or Snow Sensor 095 to automatically detect snow or ice and operates a single boiler, steam valve or electric cable to supply heat to the slab. The Watts® Home mobile application allows for remote operation and monitoring of the snow melting system from anywhere in the world.
