The Snow Detector & Melting Control 667 is a microprocessor-based control which operates a snow melting system. The control
can operate automatically when a Snow/Ice Sensor 090 is installed or the user can manually enable and/or disable the system. The
667 controls a variable speed injection pump to provide both boiler and slab protection. When the control is not in the melting mode,
the system can either be shut down or it can be maintained at an idle temperature for faster response and improved safety. The 667
control includes a large Liquid Crystal Display (LCD) in order to view system status and operating information.
Additional features include:
• Slab protection for the snow melting system
• Boiler protection
• Manual Override
• Warm Weather Shut Down (WWSD)
• Cold Weather Cut Out (CWCO) • Remote display and adjustment capabilities.
• Test sequence to ensure proper component operation.
• Pump exercising.
• Viscosity compensation.
• CSA C US Certified (approved to applicable UL standards)
