Product details

nVent RAYCHEM EMDR-10 electronic controller provides control of snow and ice melting RAYCHEM heating cables for roofs and gutters. The controller energises the heating circuits when the ambient temperature falls below a set point and moisture is detected.  The EMDR-10 saves energy using energy mode based on proportional ambient sensing control (PASC).

Features & Benefits

  • Precise control: Ambient and moisture sensing 
  • Efficiency: PASC based energy saving mode
  • Ease of use: Easy set up and programming
  • Adjustable range: -3°C to +6°C (ambient sensing) and 1  to 10 (moisture sensitivity)
  • Display: LEDs indicate operating conditions
  • Voltage: 230 VAC, ±10%, 50/60 Hz
  • Reliable: nVent RAYCHEM 6 six year available
