Features
- The KNX weather station records the wind speed, wind direction,
precipitation, global radiation, temperature, twilight, relative
humidity, air pressure and with four sensors the brightness in
different directions.
- The maximum value of the brightness sensors, absolute humidity,
perceived temperature and comfort are calculated using the
measured data.
- An area of application is the automatic, weather-dependent
shading 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. The failure is reported via a
communications object on the bus.
- With integrated bus coupler.
- Mounting outdoors on a pole or on the wall.
- The position of the installation site can be determined via GPS.
Functions
- Two limits with an adjustable hysteresis per sensor can be
parameterised internally or specified as 8-bit or 16-bit values.
- The teach-in function enables the application of a current
measured value 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 four inputs for external and internal 1-bit values.
- 4 blocking elements for blocking functions or manual operation.
- Automatic shading control system of up to 8 facades can be
implemented with sun position-dependent tracking of the slats
and hanging height control.
- All values can be output when values change and cyclically. The
outputs of the blocking elements can be sent only if the value
changes.
- Weather stations can be cascaded via the logic functions. This is
recommended for expansion of functions (measuring the wind
strength on different facades) or for significantly increased
functional reliability through redundance.
