The Snow Detector and Melting Control 664 is designed to control up to two zones in a snow melting system. The control automatically
adjusts the mixed supply water to the snow melting system by controlling up to two boilers and a single mixing device. For mixing, the
664 can use a variable speed injection pump, a fl oating action mixing valve or a 4-20 mA device. The snow melting system may be
started manually or automatically through the use of a Snow / Ice Sensor 090. The 664 control includes a large Liquid Crystal Display
(LCD) in order to view system status and operating information.
