The Snow Detector & Melting Control 664 from tekmar is designed to control a two-zone snowmelting system with two boilers. To provide slab and boiler protection, the 664 can use either a variable speed injection pump, a floating action mixing valve or a 4-20 mA device. The system may be started manually or automatically through the use of a Snow/Ice Sensor. tekmar Control Systems Ltd.
