Product Description
Control expense and energy use in electric roof cable protection automatically with Roof Sentry (RS-2). The RS-2 requires two conditions to be present before it energizes roof deicing cable: cold temperatures (ON, 38-degree F; OFF, 48-degree F) and the presence of runoff water from the roof in contact with its sensor wire. If only one of the conditions exists, the control will not energize the cable.Easy Heat RS-2 Automatic Roof De-Icing Cable Control Review
I have used eight RS2 units for two years. After lots of trial and error and some modification, they do the job. I live in an area which receives an average of 11 to 12 feet of snow each winter. Compared to using heat tape with out the RS2 controllers, they significantly reduce my electric bill while improving the prevention of ice dams. I did have to splice about 25 feet of wire on the four of them to move the water sensor from the rake of the roof, where my outlets are located, to the valleys, where the most water comes down. I also had to lace lots of heat tape at the bottom of the valleys to keep big domes of ice from overwhelming the tape.So the RS2 units work, BUT... one failed and was replaced under warranty. Now two more have failed after two years of service. There goes some of the savings in electric bills to replace those two and a lot of labor in winter conditions to remove and reinstall two units. Bummer!
PART 2: With a little disassembly and detective work I isolated the control unit, thermostat and water sensor components. Tests then showed that both units had failed with what is likely the most inexpensive component--the thermostat. I have now removed those electrically so that now I have two working control units with water sensors only. A couple of $12 Farm Innovators TC-3 units and my two failed units will be back in service for $58 each less than new RS2 units.
