Watts Tekmar WiFi Snow Melting Control 671

WiFi Snow Melting Control 671

The WiFi Snow Melting Control 671 is specifically engineered to oversee hydronic and electric heating systems, effectively melting snow and ice from road and walkway surfaces. It seamlessly integrates with the tekmar Snow/Ice Sensor 090 or Snow Sensor 095 for automatic detection of snow or ice, ensuring efficient operation. The control can manage a single boiler, steam valve, or electric cable to supply heat to the slab.

Key Features:

  • Automatic software updates keep the control system current with the latest features and enhancements.
  • Automatic snow/ice detection functionality ensures prompt response to changing weather conditions.
  • Compatible with both in-slab and retrofit aerial sensors for versatile snow and ice detection options.
  • Supports multiple zones with priority settings for optimized heating in designated areas.
  • Auto storm feature enhances system performance during inclement weather conditions.
  • Idling capability for efficient standby operation.
  • Warm weather shut down prevents unnecessary operation during warmer temperatures.
  • Cold weather cut off protects the system from damage during extreme cold.
  • EconoMelt feature helps manage energy consumption for cost-effective operation.
