The controller is used to control domestic, electric snow and ice protection systems, e.g. protection of descents, ramps, pedestrian draft against snow and ice, protection of gutters and downspouts against freezing, prevention of snow accumulation on roofs. Very easy to use, the 3-module controller is perfect for anti-freeze control of stairs, exit to the garage, as well as downpipes and gutters.
