Description
The
Weather Station Suntracer KNX sl
for the KNX building bus system measures
temperature, wind speed, brightness and air pressure. It recognises precipitation and
receives the GPS signal for time and location. In addition, using location coordinates
and the time, it calculates the exact position of the sun (azimuth and elevation).
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. Multi-function 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 of the
Suntracer KNX sl
accommodates the sensors, evalua-
tion circuits and bus-coupling electronics.
Functions:
•
Brightness measurement
(current light strength)
•
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 up to 8 façades with slat tracking and shadow edge tracking
•
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
•
Air pressure measurement
•
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
•
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
