Automatic Roof De-Icer Control
Automatic roof de-icer control. This residential grade unit automatically controls operation and energy usage of electric roof de-ice cable. The RS2 requires two conditions to be present before it energizes roof de-icing cable: both cold temperature (on 39 degrees Farenheit/9 degress Celcius) and the presence of run-off water from the roof in contact with its sensor wire. If only one of the conditions exists, the control will not energize the cable. The control is rated at 10 amps at 120 Vac, and requires one per cable.
