5. Operating Instructions
The NightmatIQ Twilight Sensor operates automatically once installed and configured. The primary setting is the twilight value, which determines the ambient light level at which the connected lights will switch on or off.
5.1 Setting the Twilight Value (Lux)
The twilight value can be individually selected between 1 and 75 lux (lx) of ambient brightness. A lower lux value means the lights will switch on when it's darker, while a higher lux value means they will switch on when it's still relatively bright.
- Locate the adjustment dial or setting mechanism on the sensor (refer to the product diagram for exact location).
- Rotate the dial to select your desired lux level. Start with a mid-range setting and adjust as needed based on your preference and local light conditions.
- Test the setting by observing the sensor's behavior at dusk and dawn.
