The Snow Melting Control 650 is designed to operate mechanical equipment to melt snow off of an outdoor slab. It can be used for any single zone electric or hydronic snow melting application that requires manual start/stop operation. This control uses Pulse Width Modulation (PWM) and slab Outdoor Reset to maintain slab temperature. It is capable of controlling a pump, valve, or electrical contact while reading outdoor air temperature.
