Operating instructions

Brightness and temperature sensor surface-mounted 7549 20 02

1. Use

The brightness and temperature sensor is suitable for brightness and temperature measurement for the KNX building management system.

2. Safety

Electrical equipment may only be installed and assembled by a qualified electrician. The national regulations and safety directions must be observed. Please observe the rules and instructions in the ZVEI/ZVEH manual for building management systems to ensure that the bus cables are laid correctly and commissioning of the KNX devices is carried out correctly. Interventions in and modifications to the device will invalidate the warranty.

3. Measurement ranges

Measurement range for brightness measurement

1 to 100 000 lux (tolerance ± 20 % resp. ± 1 Lux)

Measurement range for temperature measurement

-25 °C to + 55 °C (tolerance 5 % resp. ± 1 Grad)

(The larger tolerance applies in each case.)

4. Selecting the installation location

Please note when selecting the installation location

- that the brightness and temperature sensor is exposed to no or to minimal dirt, as a dirty sensor has an adverse effect on the brightness measurement.

- that direct sunlight can interfere with the temperature measurement.

5. Installation of the sensor

Install the brightness and temperature sensor only in a vertical position!

Consequence on non-observance

Moisture and/or dirt can get into the housing! This will result in device malfunctions and will short-circuit the bus cable.
