Read the complete manual before carrying out the installation and activating the system. Keep the manual for
future reference.
1. DESCRIPTION
The twilight switch for outdoor wall mounting is suitable for controlling outdoor lighting. Lighting control is useful for
gardens, car parks, outdoor areas and footpaths.
2. INSTALLATION
2.1. Connection
Danger: Disconnect all power before installing the twilight switch. Do not connect the device to the mains voltage until
installation has been completed.
Follow the instructions in figure 1 and refer to the wiring diagram (fig. 2).
2.2. Mounting
The twilight switch responds to changes in the ambient light intensity (fig. 3).
Tip: For optimum lighting control, aim the twilight switch to the north or the east.
Tip: Do not install the twilight switch near other light sources. Do not position the twilight switch towards the light source
it is meant to activate.
Tip: Changes in daylight level due to reflections, fallen leaves (winter/summer) or the trimming/planting of trees can affect
the switching time.
3. SETTINGS
At delivery, the light sensitivity is set at approximately 45 lux (factory setting). This lux value can be adjusted using the
potentiometer. The indication LED helps when setting the light sensor and reacts without delay. The LED illuminates when
the measured daylight level is less than or equal to the preset lux value (fig. 4).
4. OPERATION AND USE
4.1. Activation
After connecting to the mains voltage, the lighting will be:
• switched on for approximately one minute if the daylight level exceeds the preset lux value. After that, the lighting will
be switched off.
• switched on if the daylight level is below the preset lux value.
