ProMelt PM-224 Snow Sensor

Snow and ice melting systems operate best when they are connected to automatic controls.

The PM-224 sensor detects the combination of precipitation PLUS low temperature to activate a Contractor Pro control panel which in turns provides power to ProMelt Mats or Cables. It is meant to be pole-mounted open to the sky and elements and has a heated moisture sensor mounted on its top.

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.

PM-224 provides integrated air and moisture detection within a rainproof and ice-resistant enclosure. The integrated snow sensor is heated to allow for snow, ice, or freezing rain to melt, allowing proper detection of environmental conditions.

The ProMelt PM-224 offers automatic activation, rain/snow detection, adjustable trigger temperature, and a drying cycle, as well as manual operation. It must be connected to our Contractor Pro series of contactor panels.

We recommend adding the optional PM-DP remote ProMelt Display Panel for the easiest monitoring and control of your PM-224 sensor. The PM-DP wired remote is a great upgrade and is sold separately.
