2.1.3. Connection
Unsnap cover and
remove upwards
Fig. 11
1) Cover Snaps
2 Bottom part of housing
The weather station cover with the rain sensor snaps in on the left and right along
the bottom edge (see figure). Remove the weather station 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 (wire with push-connector).
Connect the Modbus data line to terminals A and B. Connect the power supply (24
V DC) to terminals 1 and 2. Ensure correct connection!
Push the connecting cable through the rubber seal on the bottom of the weather
station and connect the power and bus cables to the terminals provided for this
purpose.
The connection is by typical telephone cable (J-Y(ST)Y 2 × 2 × 0.8).
The connection cable must be plugged in between the cover and circuit board.

2.1.5. Mounting the weather station
Close the housing by putting the cover back over the bottom part. The cover must
snap in on the left and right with a definite "click".
Fig. 13
Make sure the cover and bottom part
are properly snapped together! This
picture is looking at the closed sensor
from underneath.
Fastening
Fig. 14
Push the housing from above into the
fastened mount. The bumps on the
mount must snap into the rails in the
housing.
To remove it, the weather station can be simply pulled upwards out of the mount,
against the resistance of the fastening.
Fig. 15
After installation, remove the protective sti-
cker on the wind sensor and the "distance"
sticker on the top of the cover.

2.2. Notes on mounting and commissioning
Do not open weather station if water (rain) might ingress: even some drops might
damage the electronic system.
Observe the correct connections. Incorrect connections may destroy the weather
station or connected electronic devices.
Please take care not to damage the temperature sensor (small blank at the bottom
part of the housing.) when mounting the weather station. Please also take care not
to break away or bend the cable connection between the blank and the rain sensor
when connecting the weather station.

The correct wind value may only be supplied about 10 seconds after the supply

voltage has been connected.
2.3. Maintenance of the weather station
WARNING!
Risk of injury caused by components moved automatically!
The automatic control can start system components and place people
in danger.
•
Always isolate the device from the mains for servicing and
cleaning.
The device must regularly be checked for dirt twice a year and cleaned if necessary.
In case of severe dirt, the sensor may not work properly anymore.
ATTENTION
The device can be damaged if water penetrates the housing.
•
Do not clean with high pressure cleaners or steam jets.

Transfer protocol
All characters and/or digits are based on the ASCII standard, i.e. every reading pro-
cessed internally as an integer or float value will always be broken down into and
transferred in its individual ASCII format characters. They must then be reassem-
bled in the reverse process by the receiver.
Transfer rate
19200 Baud
The checksum is calculated along by the receiver by adding all received bytes up
until byte 35 and then compared with the checksum transferred from the P03.
