The mechanical timer with twilight sensor can be operated conveniently and easily with the aid of 7 different presets; complicated programming is not required. Once set, the power supply to the connected device is automatically activated or deactivated depending on the brightness and the option set. Decide for yourself: You can switch the device on and off completely manually by selecting the “ON” or “OFF” mode or you can use one of the twilight options. In the general twilight mode, the power outlet switches on as soon as it gets dark. In the time-based twilight modes, the socket outlet also switches on at dusk, but then switches off again after a certain period (2/4/6/8 hours). This allows you to decide for example when and how long you want your lighting to stay on in the evening.
