3 Description
Rain/Wind Sensor KNX RW • Status: 10.06.2021 • Technical changes reserved. Errors reserved.
1. Description
The Rain/Wind Sensor KNX RW measures precipitation and wind speed and trans-
fers the values to the KNX system. Four switching outputs with three adjustable thresh-
old values as well as additional AND and OR logic gates are available. The sensor sys-
tem, the evaluation electronics and the electronics of the bus connection are mounted
in a compact housing.
Functions:
•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
•Wind measurement: The wind strength measurement takes place
electronically and thus noiselessly and reliably, even during hail, snow and
sub-zero temperatures. Even turbulent air and anabatic winds in the vicinity of
the weather station are recorded
•4 switching outputs (communication objects), 3 with adjustable
threshold 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
Configuration is made using the KNX software ETS. The product file can be down-
loaded from the Elsner Elektronik website on www.elsner-elektronik.de in the “Ser-
vice” menu.

4 Installation and commissioning
Rain/Wind Sensor KNX RW • Status: 10.06.2021 • Technical changes reserved. Errors reserved.
The product conforms with the provisions of EU directives.
2. Installation and commissioning
Installation, testing, operational start-up and troubleshooting should
only be performed by an authorised electrician.
DANGER!
Risk to life from live voltage (mains voltage)!
There are unprotected live components inside the device.
• Inspect the device for damage before installation. Only put undamaged devic-
es into operation.
• Comply with the locally applicable directives, regulations and provisions for
electrical installation.
• Immediately take the device or system out of service and secure it against un-
intentional switch-on if risk-free operation is no longer guaranteed.
Use the device exclusively for building automation and observe the operating instruc-
tions. Improper use, modifications to the device or failure to observe the operating in-
structions will invalidate any warranty or guarantee claims.
Operate the device only as a fixed-site installation, i.e. only in assembled condition and
after conclusion of all installation and operational start-up tasks, and only in the sur-
roundings designated for it.
Elsner Elektronik is not liable for any changes in norms and standards which may occur
after publication of these operating instructions.
2.1. Location
Select an assembly location at the building where precipitation and wind may be col-
lected by the sensors unobstructedly. Do not assemble any construction components

above the sensor from where water may drop on to the rain and wind sensor after it
has stopped raining or snowing.
At least 60 cm of clearance must be left all round the device. This facilitates correct
wind speed measurement without eddies. The distance concurrently prevents spray
(raindrops hitting the device) or snow (snow penetration) from impairing the measure-
ment. It also does not allow birds to bite it.
2.2. Mounting the sensor
2.2.1. Attaching the mount
The sensor comes with a combination wall/pole mount. The mount comes adhered by
adhesive strips to the rear side of the housing. Fasten the mount vertically onto the wall
or pole.
Fig. 1
There must be at least 60 cm of space below,
to the sides and in front of the sensor left
from other elements (structures, construction
parts, etc.).

The rain/wind sensor must be mounted on a
vertical wall (or a pole).

Different mounting arms are available from Els-
ner Elektronik as additional, optional accessories
for flexible installation of the weather station on
a wall, pole or beam (pictures of sensors exem-
plary).
Example of the use of a mounting arm: Due to
flexible ball joints, the sensor can be brought
into ideal position.

Example use of the hinge arm mounting:
With the hinge arm mounting, the weather sta-
tion projects from beneath the roof overhang.
Sun, wind and precipitation can act upon the
sensors without hindrance.

2.2.3. Preparing the sensor
The sensor cover snaps in on the left and right along the bottom edge (see Fig.). The
cover of the 230V model is also screwed on top. Remove the cover. Proceed carefully,
so as not to pull off the wire connecting the PCB in the bottom part with the rain sensor
in the cover (soldered cable connection in case of 230 V AC version, cable with plug in
case of 20...32 V DC version).
Lead the cable for the voltage supply and bus connection through the rubber seals on
the bottom of the device and connect Voltage L/N and Bus +/- to the terminals provid-
ed.
For 20...32 V DC devices the connection cable must be plugged in between the cover
and circuit board.
