We reserve the right to make technical modifications
Electrical connection
An on-site overload current protection device (fuse) and a
disconnecting and isolating switch to switch off the entire
unit must be provided.
Use a line that is approved for the operating voltage
and is resistant to weather and UV rays (suitable for
outdoor use), e. g. as 4 x AWG 20 UL SW.
The supply line must be routed so that water cannot
enter into the device or into the building.
The total line length must not exceed 1,200 m if a
twisted pair line is used and routed in an interference-
proof manner.
Pay attention to the minimum voltage at the weather
station (voltage drop) and use a separate power supply
unit for the power supply if necessary.
Connect the weather station to the Omnexo Central
control unit as per wiring diagram Fig. 6 on page 5.
The bus lines must be provided with terminating
resistors at the beginning and end of the line.
HUBs are needed for longer line lengths.
If you are using the optional Omnexo Weather station
pro power supply unit 24 V DC/1.3 A AP (article
number 2057430), a branch line of max. 10 m to the
Omnexo Weather station pro is permissible
Please take out the ID labels
from the devices
and give them to your system integrator (see also page
4). A clear allocation of the devices and ID labels must
be ensured.
This device meets the requirements on electromagnetic
immunity and electromagnetic interference for use in
residential and commercial environments.
For operation, an external power supply unit must
be installed in the vicinity of the Omnexo Weather
station pro.
If the Omnexo Weather station pro is the last bus
device in the bus line, the terminating resistor
needs to be manually set (see Fig. 6 on page
5, illustration displays active terminating resis-
tor)
Depending on the installation situation, you can
also directly route the line of type JY(St)Y to the
Omnexo weather station pro. It must be ensured
that the line is protected against UV radiation (e.g.
in a conduit, tube) along its entire length.
Commissioning
To be able to commission the weather station, it must be
set up in the Omnexo software. To determine the serial
number, place the magnet (in central control unit scope of
delivery) on the ID label until the status LED lights up for
confirmation. (see Fig. 6 on page 5.)
Alternatively, you can manually enter the serial number
manually (see label on device).
When commissioning, note that the weather station
has an internal temperature correction feature that
improves measurement accuracy.
When the operating voltage is first switched on, a
temperature measurement is taken at the weather
station.
Maintenance
There are no parts within the device that require
maintenance.
Cleaning
The weather station should be checked for dirt (e.g. bird
droppings) and cleaned carefully four times a year.
Clean the device with a soft damp cloth. Steam or high
pressure washers, abrasive sponges, abrasive agents
and solvents such as alcohol or petroleum must not be
used!
Liability
Failure to comply with the product information in these
instructions and any use of the device other than its
intended use may result in the manufacturer refusing to
honour warranty claims for product damage. In this case,
liability for secondary harm to persons or damage to
property will also be excluded. Observe the information in
the operating instructions for your sun shading system. The
automatic or manual operation of the sun shading system
while iced over and the use of the sun shading system
during severe weather may cause damage and must be
prevented by the operator through suitable precautions.
Obligations for the disposal of electrical
devices
A marking with this symbol indicates the following
obligations under the scope of legal regulations:
The owner of this electrical device must dispose of it
separately from unsorted municipal waste for further
recycling.
Used batteries and accumulators that are not enclosed
in the old device, as well as lamps/bulbs that can be
removed from the old device without breaking, must be
disposed of separately.
Distributors of electrical devices and disposal
companies are obliged to take back the equipment free
of charge.
The owner must take it upon themselves to delete any
personal data contained in the electrical device prior to
disposal.
