Features:
- The weather station Plus for KNX detects the wind speed, wind direction,
precipitation, global radiation, temperature, twilight, relative humidity and
air pressure as well as determining brightness directionally using four
sensors.
- The measured data is used to calculate the maximum value for the brightness
sensors, absolute humidity, perceived temperature and comfort level.
- Area of use is the automatic, weather-dependent shading control system
specifically for home use.
- The weather station monitors some of its own major functions and reports
corresponding faults automatically via message objects on the bus.
- Monitoring of the applied voltage. Failure is reported using a communication
object on the bus.
- With integrated bus coupler.
- Mounting outdoors on a pole or on the wall.
- The position of the mounting location can be determined using GPS.

Functions
- Two limit values with adjustable hysteresis for each sensor can be
parameterised internally or specified as 8-bit or 16-bit values.
- A teach-in function enables the current measured value to be applied to a
limit.
- All limit objects have a parameterisable switch-on and switch-off delay.
- 16 logic gates (AND, AND with return, OR, exclusive OR, NAND, NOR) with up
to 4 inputs for external and internal 1-bit values.
- Four blocking elements for disabling functions or manual operation.
- An automatic shading control system for up to 8 facades can be realised with
sun position-dependent slat tracking and a hanging height control system.
- All values can be output in the event of a change of value or on a cyclical
basis. The outputs of the blocking elements can only be sent in the event of a
change of value.
- Weather stations can be cascaded using the logic functions. This is
recommended for upgrading functions (measurement of the wind speed on
different facades) or for a significant increase in functional reliability due
to redundancies.
