The SMMC-3 Control Panel manages snow and ice melting systems for sidewalks, driveways, gutters and downspouts. Suitable for controlling all types of heating cable systems, the SMMC-3 can monitor snow and ice accumulation in three separate zones. The SMMC-3 programming allows each zone to be controlled independently or on a priority mode basis.
The SMMC-3 is housed in an enclosure suitable for commercial/industrial applications (NEMA 12) and features an LCD display, programming and associated indicator lights for operation of each zone.
The control signal relays operate external contactors.
The SMMC-3 can access information from three different types of moisture sensors - surface (SMPS-1), aerial (SMAS-1) and gutter (SMGS-1) and one type of temperature sensor (SMTS-1). The surface, aerial and gutter sensors detect moisture from snow, ice, sleet, etc. and send appropriate signals to the SMMC-3. Similarly, the temperature sensor sends temperature data back to the SMMC-3. Independent temperature and moisture information is processed by the SMMC-3 to ensure that heating equipment will only be energized when precipitation occurs during freezing conditions. For each of the SMMC-3 control zones, up to two individual moisture sensors can be connected. However, for each zone only one of these may be a surface sensor. Each SMMC-3 must have a temperature sensor, SMTS-1, in order to function. The SMTS-1 is included with each SMMC-3.
