Suntracer KNX sl

KNX Weather Stations

The weather stations "Suntracer sl" for the KNX building bus system measure temperature, wind speed, brightness and recognise precipitation.
All values can be used for the control of limit dependent switching outputs. States can be linked via AND logic gates and OR logic gates. Multifunction modules change input data as required by means of calculations, querying a condition, or converting the data point type. The integrated shade control system allows intelligent sun protection control of up to 8 façades.
The compact housing accommodates the sensors, evaluation circuits and bus-coupling electronics.

Models:


N° 70154 Suntracer KNX sl with air pressure sensor, GPS receiver and shading control for 8 facades (with tracking of the slats and shadow edge)
N° 70155 Suntracer KNX sl light GPS receiver and shading control for 5 facades
N° 70156 Suntracer KNX sl basic

  • Brightness measurement(current light strength)
  • Wind measurement: The wind strength is measured electronically and thus noiselessly and reliably, even during hail, snow and sub-zero temperatures. Even turbulent air and rising winds in the vicinity of the device are recorded
  • Precipitation detection: The sensor surface is heated, so that only drops and flakes are recognised as precipitation, but not mist or dew. When the rain or snow stops, the sensor is soon dry again and the precipitation warning ends
  • Temperature measurement
  • Frost protection for shading systems
  • Switching outputs for all measured and computed values. Threshold values can be adjusted per parameter or via communication objects
  • 8 AND and 8 OR logic gates each with 4 inputs. All switching events as well as 16 logic inputs (in the form of communications objects) can be used as inputs for the logic gates. The output of each gate can be configured optionally as 1-bit or 2 x 8-bit
  • 8 multi-function modules (computers) for changing the input data by calculations, by querying a condition or by converting the data point type
  • Configuration is made using the KNX software ETS

Suntracer KNX sl and Suntracer KNX sl light additionally:

  • GPS receiver outputting the current time and location coordinates. The weather station Suntracer KNX sl also computes the position of the sun (azimuth and elevation)
  • Shade control for 5 or 8 facades (depending on model). Suntracer KNX sl: with slat tracking and shadow edge tracking
  • Weekly and calendar time switch: All time switching outputs can be used as communication objects. The weekly time switch has 24 periods. Each period can be configured either as an output or as an input. If the period is an output, then the switching time is set per parameter or per communication object. The calendar time switch has 4 periods. Two on/off switching operations, which are executed daily, can be set for each period
  • Summer compensation for cooling systems. A characteristic curve matches the target temperature in the room to the external temperature and sets the minimum and maximum target temperature values

  • Air pressure measurement
