Image of EMDR-10 Snow Melting Thermostat

The EMDR-10 is used to ensure an energy efficient operation of the gutter snow melting sytem Icestop GM-2X and Icestop GM-2XT. Equipped with a temperature and moisture sensor, the thermostat only activates the system when detecting moisture and temperatures below zero, to ensure effective drainage of snowy water.


  • Compatible with GM-2X and GM-2XT cables
  • Dual sensor only activates when necessary : cold & wet
  • Savings up to 80% possible


  • Alarm relay contact for sensor break, sensor short circuit and power failure.
