When activated, the 2-way remote control sends signals to the actuators of the convenient electrical installation. The mobile device is powered by a button cell (CR2430). The functions can be assigned individually, whereby no distinction is necessary between blinds, dimmers, switching, etc. An LED shows whether the signal has been sent, but also correctly understood and confirmed. The remote control can be easily attached to a key chain (included in delivery). An optional wall mount using a magnet is possible (110771, must be ordered separately). Battery included in delivery.
