GENERAL FEATURES AND FUNCTIONALITY
KNX weather station
Weather station, KNX standard, power supply 12-32 Vdc or
12-24 Vac. Can be integrated with the By-me home auto-
mation system.
General information
The device measures quantities such as temperature, wind
speed, rainfall, and brightness whose values can be used
for viewing on supervisors or, on exceeding a threshold, to
activate automation systems in the installation. The KNX
weather station 01546 can be integrated with the By-me home
automation system via a dedicated configuration using the
EasyTool Professional software.
Characteristics
• Auxiliary supply voltage AUX: 12-32 V , 12-24 V~ SELV
• AUX current draw: 100 mA max, ripple 10%
Current draw from the Bus: 10 mA
• Terminals:
- Auxiliary power supply AUX
- TP bus connector
• Configuration push-button
• Configuration LED
• Configuration LED: 254 max
• Possible associations: 255 max
• Communication objects: 109
• Rain sensor heating: approximately 1.2 W
• Temperature measurement range: -40°C to +80°C
• Definition (temperature): 0.1°C
• Accuracy (temperature):
- 1°C with -10°C - +85°C
- 1.5°C with -25°C - +150°C
• Wind measurement range: 0 - 70 m/s
• Definition (wind): <10% of the reading
• Accuracy (wind): 25% with 0 - 15 m/s with an angle of
incidence of 45° and mounting on a suitable support
• Brightness measurement range: 0 - 150,000 Lux
• Definition (brightness):
- 1 Lux with 0-120 Lux
- 2 Lux with 121-1,046 Lux
- 63 Lux with 1,047-52,363 Lux
- 423 Lux with 52,364-150,000 Lux
• Accuracy (brightness): 35%
• Operating temperature: -30°C - +50°C (outdoor use)
• Protection class: IP44
• Dimensions: 96x77x118 mm (W x H x D)
• Weight: approximately 170 g
Operation
• Brightness measurement: the current brightness is measured
by the specific sensor.
• Wind measurement: the strength of the wind is measured
electronically and is quiet and reliable even in the event of hail,
snow and sub-zero temperatures.
The weather station is also able to detect whirlwinds and
updraughts.
• Precipitation measurement: the weather station is equipped
with a sensor with a heated surface so that only the raindrops
and snowflakes (and therefore not fog or dew) are measured
as precipitation. Once it has stopped raining or snowing, the
sensor dries quickly and the precipitation message is turned
off.
• Temperature measurement: the weather station measures
the value of the current ambient temperature.
• Control outputs for all values: the limit values can be set
via the respective parameters or via the ETS communication
objects.
• 8 AND logic gates and 8 OR logic gates each one with
4 inputs: the control operations themselves as well as the
8 logic inputs (in the form of communication objects) can be
used as inputs for the AND and OR logic gates; the output of
each gate can be configured as 1 bit or as 2 x 8 bits.
IMPORTANT: Press the configuration button to assign
the physical address to the device.
Behaviour after switching on the Bus
Switching on the Bus: the state will be set based on the setting
of the parameters and the corresponding telegrams sent over
the Bus.

1. Fast spring terminal for auxiliary power supply AUX; terminal assignment
is independent of polarity (+/- or -/+). Use a solid cable of cross-
section up to 1.5 mm2or a stranded cable.
2. Connector for connecting the cable of the precipitation sensor located
under the front cover of the weather station.
3. Space for feeding through the power supply cable and the Bus cable.
4. KNX TP Bus connector (-, +). We recommend using the KNX cable art.
01890 using a corrugated pipe for the outside or to protect the cable
from UV radiation.

Note: If the threshold value is set by a communication object,
the threshold value must be specified during configuration
because this value remains valid until the 1st object is sent with
the new threshold value. In the case of weather stations that
have already been put into service, the last threshold value sent

using the parameter or a communication object, the last set

Continued Note: If the threshold value is set by a communication object,
the threshold value must be specified during configuration
because this value remains valid until the 1st object is sent with
the new threshold value.
In the case of weather stations that have already been put into
service, the last threshold value sent by the communication
object is used.
If a threshold is set once using the parameter or a communication
object, the last set threshold value remains until a new threshold
value is transmitted by a communication object.
The last threshold values set by the communication objects are
saved in EEPROM memory, so as to preserve the values during
a power failure that are then available when power is restored.
