Product Details

Tekmar 671

The Wi-Fi 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.
