17. Resetting to factory settings
Press the programming keys (programming key/UP/DOWN keys/limit stop switch and DOWN
key) about 10 seconds until the motor jerks 1 x after 3 seconds, 1 x after 6 seconds and 4 x
after 10 seconds. Then the motor is reset to factory settings and the referencing is activated.
18. Antifreeze protection
The electronic control can monitor the ambient temperature and respond to it. This function is
enabled in the standard delivery state.
If a fixed outdoor temperature is reached, the blind moves up a little bit to prevent the end rail
from freezing.
If the temperature exceeds or falls below the threshold for safe charging of the battery, this will
be indicated on the LED display.
Temperature too high: green and yellow LEDs flash.
Temperature too low: green and red LEDs flash.
The blind can still be operated until the critical battery status is reached. As soon as this
happens, the blind is moved to the upper position and remains there until the battery is fully
charged.
Yellow and red LEDs flash.
19. Recommissioning after use
The system can only be put back into operation if the mains voltage is restored and the
signalling contact (central fire alarm system connection) is closed again or when the critical
battery capacity is again above the set level (>50% capacity).
If these requirements are met, the system returns to manual operation.
After operation, the entire system (Venetian blinds, operating switch, drive and electronics)
needs to be checked again.
Green LED lights up.
