Introduction
The Snow Melting Control 654 is designed to operate electric or hydronic equipment to melt snow or ice from any surface
including driveways, walkways, patios, business entrances, parking ramps, loading docks, hospital entrances, helipads
or car wash bays. The surface temperature for snow melting is controlled automatically to reduce operating energy costs.
The 654 has an automatic start and stop function when used with the Snow/Ice Sensor 090 or 094. Automatic start with a
timed stop is available when used with the Snow Sensor 095. The 654 can operate a dedicated hydronic boiler or a mixing
device. Isolation relays are required to operate line voltage pumps. Electric systems require a separate GFCI and electrical
relay contactor.
