WiFi Snow Melting Control 670

The WiFi Snow Melting Control 670 is designed to manage both hydronic and electric heating systems, facilitating the melting of snow and ice from road and walkway surfaces. It seamlessly interfaces with the tekmar Snow/Ice Sensor 090 or the Snow Sensor 095 for automatic snow and ice detection, ensuring efficient operation. The control can operate a single boiler, steam valve, or electric cable to supply heat to the slab.

Key Features:

  • Mobile app compatibility for iOS and Android platforms, enabling remote control via the Watts® Home mobile app.
  • Automatic software updates ensure the control stays up-to-date with the latest features and enhancements.
  • Supports automatic snow/ice detection with compatibility for both in-slab and retrofit aerial sensors.
  • Multiple zones with priority support, ensuring efficient heating in designated areas.
  • Idling feature for optimized system performance during standby periods.
  • Auto storm and warm weather shut down functions enhance system efficiency and protect against unnecessary operation.
  • Cold weather cut-out feature prevents damage to the system during extreme temperatures.
  • EconoMelt functionality helps manage energy usage for cost-effective operation.
  • Slab protection ensures durability and longevity of the heating system.
  • Tandem snow/ice detection feature improves accuracy and reliability of snow detection.
  • Equipment exercising capabilities help maintain system health and functionality over time.
