The points to check before selecting a motorised system: 1. Number, size and weight of each shutter. 2. Position of the shutter hinges. 3. The space available to install the motor, i.e. space between the window and the closed shutters and width of the window. 4. What type of installation do you want for the motor? Under the window lintel, intermediate (on a balustrade, for example, or on the window sill (in the case of an arched window)? 5. What colour do you want for the motor housing? Several colours are available to match your shutters or joinery. 6. Is there a power supply near the windows in question?
