Daylight Sensor
The light sensor measures the total amount of light in a circular eld of ≈80% of the PIR detection area. The following aspects should be observed
during installation:
• Minimum distance from the window ≥ 2.0 '/0.6 m .
• Prevent light reections from outside entering the sensor (for example sunlight reection on a car bonnet) as this will lead to incorrect
light regulation.
As a guideline the formula 0.72 x H can be used to calculate the minimum distance between the window and sensor whereby H is the height
from the bottom of the window to the ceiling.
