WiFi Snow Melting Control 671
User Manual
Introduction
The WiFi Snow Melting Control 671 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. The Watts ® Home mobile application allows for remote operation and monitoring of the snow melting system from anywhere in the world.
Manual Melting Operation
Manual Start and Timed Stop
- Start from Control display
- Start from Watts® Home mobile app
- Start from manual switch contact

Automatic Melting Operation
Automatic Start and Stop
The Snow/Ice Sensor 090 or 094 is installed in the road or sidewalk.
Automatic Start and Timed Stop
• The Snow Sensor 095 is installed on a pole outside the building.
The automatic sensors require regular cleaning at least once per year to ensure reliable operation. Clean the sensor with hot soapy water and scrub with a nylon brush, then rinse and wipe clean with a cloth.
User Interface 
The snow melting system operates in one of these five modes:
| SYSTEM IS MELTING
The control has either detected snow/ice and automatically started or the
control was manually started.
---|---
| SYSTEM IS IDLING
The control is pre-heating the slab to the idling temperature. This reduces
the amount of time needed to reach the melting temperature in the event snow
or ice is detected.
| SYSTEM IN OVERRIDE
The control is in a manual override for testing purposes or manually disabled.
| SYSTEM IS OFF
The snow melting system is off and is ready to detect snow or ice.
| STORM PREDICTED
The storm feature can be manually started through a user switch. This reduces
the amount of time needed to reach the melting temperature in the event snow
or ice is detected.
