Product description
The Weather Station
measures temperature, wind speed and
brightness. It perceives precipitation and receives the DCF77 signal for date and time.
Furthermore, the exact position of the sun (azimuth and elevation) is calculated on the
basis of location coordinates and time.
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.
All data may be used for the control of switching outputs which depend on threshold
values. The states may be linked by means of AND and OR logic gates.
The compact housing of
stores the sensor system, the evaluation
electronics and the electronics of the bus connection.
Functions and Operation:
•
Brightness and position of the sun
: The current light intensity is measured by
means of a sensor. At the same time, Suntracer KNX calculates the position of the
sun (azimuth and elevation) on the basis of time and location. The necessary
position coordinates (degree of longitude and latitude) are entered into the ETS
software
•
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 DCF77 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
•
Switching outputs
for all measured and calculated values (Threshold values can
be set by parameter or via communication 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
