3 Function
System information
This device is a product of the KNX system and complies with the KNX directives. Detailed
technical knowledge obtained in KNX training courses is a prerequisite to proper understanding.
The function of this device depends upon the software. Detailed information on loadable
software and attainable functionality as well as the software itself can be obtained from the
manufacturer´s product database. Planning, installation and commissioning of the device are
carried out with the aid of KNX-certified software. The latest versions of product database and
the technical descriptions are available on our website.
Intended use
- Measurement and evaluation of weather data: Wind speed, Wind direction, Precipitation,
Brightness, Global radiation Twilight, Temperature, Relative air humidity and Air pressure
- Installation on the outside of buildings, preferable in the roof and facade area
- Operation with additional power supply (see accessories)
Product characteristics
- Integrated GPS/GLONASS receiver for automated positioning
- Calculation of additional weather data: Absolute air humidity, chill temperature, comfort
- Function for shading control
- Integrated KNX bus coupling unit
- Measurement data acquisition and limit value monitoring
- Software logic modules for linking events
- Integrated heating
iThe measured values apply to the mounting location. Variations to other weather services
– e.g. through local turbulence or areas with build-ups of air – are possible.
4 Information for electrically skilled persons
DANGER!
Electrical shock on contact with live parts in the installation environment.
Electrical shocks can be fatal.
Before working on the device, disconnect the power supply and cover up live
parts in the working environment.

Figure 5: Maximum load on the fastening arm
Select a mounting selection in which the weather station is not influenced by local obstacles or
shading, such as surrounding trees, chimneys, awnings, etc. The sensor must be able to detect
wind, rain and ambient brightness without impedance. Avoid slipstream, shadow casting and
light reflection.
Preferred mounting on a freestanding mast. If mounted on house walls, the measurement of
wind and brightness in particular can be distorted.
Do not mount it below or next to building sections, from which water can drip onto the device.
Select the mounting location so that the weather station will be accessible.
In the case of flat roofs, locate the weather station as close to the centre of the roof as possible.
Minimum distance to surfaces below the weather station: 0.6 m (figure 3). Otherwise, the
sensors on the underside may get damaged by penetrating spray water (figure 4).
Direct sunlight, chimneys or other waste gas or ventilation systems affect the temperature
measurement.
Do not operate in the vicinity of radio transmitter systems. Doing so will compromise function.
iDo not connect more than 3 weather stations in a KNX line.
Mounting weather station without fastening arm on freestanding mast

oMount enclosed guide blade (11) in the fields provided next to the connection (7).
iIf mounted on a mast without the guide blade, no correct wind direction measurement is
possible due to the resulting turbulences.
oRoute the power supply line through the mast.
oAttach the 7-pin plug to the connection (7). Tighten threaded ring with max. 0.5 Nm.
oMount weather station onto the mast and align. The grub screw (2) must be pointing north.
oTighten grub screw (2) with max. 0.6 Nm.
Mounting weather station with fastening arm on mast or wall
Figure 7: Mounting with fastening arm
Mount enclosed fastening arm onto a suitable mast or wall.
The enclosed hose clamps are suitable up to a maximum mast diameter of 60 mm.
iIf mounted on the supplied fastening arm, do not mount the enclosed guide blade.
oMast mounting: Attach fastening arm to mounting mast using the enclosed hose clamps.
oWall mounting: Attach fastening arm to the wall through the boreholes (figure 8) using
suitable screws.
oRoute the power supply line along the underside of the fastening arm and guide the 7-pin
plug through the open pipe socket at the end of the fastening arm.
oAttach the 7-pin plug to the connection (7). Tighten threaded ring with max. 0.5 Nm.
oMount weather station onto the mast and align. The grub screw must be pointing north.
oTighten grub screw with max. 0.6 Nm.
oRoute the power supply line through the cable bushing into an installation pipe.
