KNX Weather Stations

The KNX weather stations measure temperature, wind speed and brightness.They recognise precipitation and receive the GPS signal for time and location. In addition, using location coordinates and time,they calculate the exact position of the sun (azimuth and elevation).
All values can be used for the control of threshold value-dependent switching outputs. States can be linked via AND logic gates and OR logic gates. The compact housing accommodates the sensors, evaluation circuits and buscoupling electronics.

The calculation of the position of the sun is optimised for UTC -1...+3. The device therefore may only be applied within Europe. For other time zones, please use Suntracer KNX-GPS Weather Station.

  • Brightness and position of the sun: The current light intensity is measured by means of a sensor. At the same time, the weather station calculates the position of the sun (azimuth and elevation) on the basis of time and location.
  • Shade control for 5 facades
  • Wind measurement: The measurement of wind speed is accomplished electronically and thus noiseless and reliable even in case of hail, snow and minus temperature. Air swirls and up-draught in the radius of the weather station are collected, too
  • Precipitation perception: The surface of the sensor is heated so that only drops and flakes are recognised as precipitation but not fog or dew. If it stops raining or snowing, the sensor dries quickly and the precipitation message ends
  • Temperature measurement
  • Week and calendar time switch: The weather station receives time and date from the integrated GPS receiver. The week time switch operates up to 4 different periods each day. With the calendar time switch, you may determine 3 additional periods where the time switch accomplishes up to 2 activations and deactivations each day. The Switching outputs can be used as communication objects. The switching times are set by parameter or via communication objects
  • Threshold values for all measured and calculated values can be set via parameters or communications objects
  • 8 AND and 8 OR logic gates with each 4 inputs. Every switching incident as well as 8 logic inputs (in the form of communication objects) may be used as inputs for the logic gates. The output of each gate may optionally be configured as 1 bit or 2 x 8 bits
  • Configuration is accomplished by means of the KNX software ETS
