The PM-HSC5 is a surface mounted snow detector. It is used to detect snowfall and low temperature and then automatically activate the ProMelt Mats or Cables via a CP panel. It has built-in temperature and moisture detection and a drying cycle (not adjustable) after snow melting is complete. It is comprised of a sensor and sensor socket that is embedded in the slab level with the surface where ProMelt is installed.
The PM-HSC5 is a 24 volt, self contained snow and ice detector intended to be installed in a concrete slab or other masonry material. Each PM-HSC5 is designed to operate on supplied 24 V power. The snow sensor is heated to allow for snow, ice, or freezing rain to melt, allowing proper detection of environmental conditions. This Low voltage control cannot operate alone – it must be connected to and powered by a contactor control panel. For standalone operation, choose the PM-2B or PM-5 sensor-controllers.
The HSC5 Pavement-Mounted Deicing Controller reliably operates snow and ice melting heaters based upon pavement condition. The HSC5 activates systems for snow and ice melting at pavement temperatures below 38 degrees F (3.3 degrees C) while moisture in any form including water, snow, sleet or ice is present. Once the sensor element has dried, the fixed 5 hour hold-on timer keeps heaters operating. This sensor operates in conjunction with our Contactor Pro series of ProMelt controls, ordered separately.
The HSC5 accurately measures pavement temperature by compensating for its internal heating. This eliminates the cost and complexity of a separate pavement temperature sensor. For improved efficiency, products mount close to the deicing heaters to ensure that pavement and sensor become dry at about the same time
