The remote control is supplied with a suction cup that is used to be attached inside of the window glass. It has an outdoor light sensor, which can place the roller shutter in the indicated position, when the external brightness exceeds the programmed value

• Frequency 433.92 MHz. Compatible with enjoy R4
• S4GLASS is built in timer, so user can also set 4 up coomands and 4 down commands for the roller shutter
• This sensor has a command button, which allows the user open or close the roller shutter when he needs
• Powered by battery CR2032 

Once selected light intensity (brightness) in the sensor sensor:

• when the brightness exceeds the threshold, the roller shutter will descend until cover the sensor and then it reverser up some centimeters to leave sensor uncovered to continue checking the outer brightness 
• when the brightness falls below the threshold, the roller shutter will goes up until its upper limit
• When the brightness is almost zero, sun sensor is deactivated, so roller shutter can commanded manually from a remote control and avoid at night automatic movements

1. In the morning, a setted timing command opens the roller shutter at 6:15
2. During the morning, when the outdoor luminosity is higher than that programmed, sensor send a command to place the shutter above the sensor
3. In the afternoon, the user reopens the roller shutter completely, allowing the last rays of light to enter the house
4. At nightfall, a setted timing command closes the roller shutter. As brightness is very low, sun sensor is deactivate, so roller shutter will remain closed until next day
