The IC GR-300 is a module for shading and controlling roller shutters, awnings, blinds and curtains in the digitalSTROM system. It is installed in a sub-distribution on the DIN rail (1 TE). The module enables different types of shading - freely configurable using software - to be intelligently networked in the digitalSTROM system via the 230V line. This means you can conveniently control opening and closing using a digitalSTROM button and automate it as desired - for example according to the time of day, weather conditions or as a presence simulation. It is also possible to control several shading devices together in one room or the entire apartment or house. The desired shading positions can be called up remotely at any time using the smartphone app. Up/down function can be configured for 1-way and 2-way buttons.
