The ground and roof sensors both measure two things on the sensor surface:
• temperature
• moisture from ice, snow, hail or rain
These measurements are input to the DEVIreg™ 850, and it
decides how the ice and snow melting system should control
the heated areas.
Details about the setup of the controller can be found in the
DEVIreg™ 850 installation manual.
