WiFi Snow Melting Control 670
User Manual
Introduction
The WiFi Snow Melting Control 670 operates hydronic and electric heating equipment designed to melt snow and/or
ice from roads and walkway surfaces. The control works with the 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.
Boiler return protection is provided to non-condensing boilers using a mixing valve or variable speed injection mixing
pump. The tekmar Connect mobile application allows for remote operation and monitoring of the snow melting system
from anywhere in the world.
