The Snow Detector & Melting Control 665 is a microprocessor-based control which operates a single zone 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. When the control is in the melting mode, the slab is maintained at a “Melting” temperature through an on/off output which
operates a contactor for electrical cables, a boiler, an injection pump or an injection valve. When the control is not in the melting mode,
the melt system can either be shut down or it can be maintained at an idle temperature for faster response and improved safety. The
665 control includes a large Liquid Crystal Display (LCD) in order to view system status and operating information.
