Somfy Part Number: 1001553 In new constructions and where few products require controls, Wired Technology links the control device to the motor using electrical wires that are embedded into the wall. When choosing Wired control units, electrical feeds must be well-thought-out prior to construction and future renovations need to be foreseen. Manual controls must be located near windows and in strategic areas, as we know that otherwise, shading devices and roller shutters are used less often.
