ARNINGW
The electrical installation (assembly)/dis-
mantling must be performed by a certified
electrician in accordance with VDE0100
or the legal requirements and standards
of the country in which the device is being
installed. The electrician must observe the
installation instructions included with the
supplied electrical devices.
Due to both the legal regulations for radio systems and
structural factors, the operating range of radio remote
controls is limited. Sufficient radio reception must be
ensured when planning the project. This is especially the
case where the radio signal must pass through walls and
ceilings. The control should not be installed in the immedi-
ate vicinity of metal components (steel beams, reinforced
concrete, fire doors).
 Therefore, check that the receiver is functioning proper-
ly before the final installation.
Strong local transmitter systems (e.g. WLAN) with trans-
mission frequencies identical to those of the control may
interfere with reception.
Installation
The device is intended for flush mounting in a building.
Use suitable fixing materials only.
Important information on the installation location
The device is designed for installation in a flush-mount-
ed junction box 80 x 80 mm. The space in a 60 mm
flush-mounted switch box is usually not sufficient.
 Only lines that are used for the wiring of the WMS Split-
ter UP should be routed into this box.
 Install the WMS Splitter UP in such a way that the bot-
tom of the housing with the printed radio waves symbol
points towards the opening of the box. This ensures
the best possible radio reception.
 Check that the WMS Splitter UP is functioning properly
before final installation.
 Metal-clad buildings, domestic interference sources
(unshielded household appliances, television sets, com-
puters), supply lines and metallic objects such as sheet
metal enclosures must have a distance of at least 0.5
m from the WMS Splitter UP.
 When performing the installation, follow the separate
instructions of all components being connected, e.g.
when installing the weather station(s), follow the specifi-
cations in the corresponding instructions.

The WMS Splitter UP is a flush-mounted device that en-
ables the distribution of weather data from one or more
central weather stations in several WMS networks. The first
WMS Splitter UP is connected to the weather station and
controls the weather station as a "master". Further WMS
Splitter UPs serve as "slaves" and forward the weather data
that is received. This means, for example, that in a building
with several residential units, weather data from the weath-
er station can be transmitted via several WMS Splitter UPs.
Intended use
The WMS Splitter UP is an electronic device to forward
weather data and thus to control WMS receivers. The
device is designed for interior installation. Any use other
than the purpose described in these instructions requires
approval from the manufacturer.
Safety instructions
These instructions address persons mounting, wiring or
connecting the WMS Splitter UP and all necessary parts.
Please contact your specialist dealer if you need additional
information.
Valid from
1 November 2022
Keep for future
use.

Electrical connection
An on-site overload current protection device (fuse) and a
disconnecting and isolating switch to switch off the entire
system must be provided.
The unit is electrically connected according to the wiring
diagram on the reverse (Fig. 3 on page 4).
Commissioning
Further information and aids such as video
guides and the WMS practical manual can
be found on our support site.
www.warema.com/radio-systems-support
We recommend commissioning using the
WMS studio pro PC software!
For the bus communication to operate properly, only one
WMS Splitter UP (as a "master") may request the measur-
ing values of the connected weather station(s). By default,
all encoding switches are in the OFF position. ("slave").
To activate the "master" function, the encoding switch
S3(1) must be set to the ON position.
One "slave" WMS Splitter UP is required per WMS network
and a maximum of 200 slaves can be connected in one
network.

Connecting the RS485 side
All WMS Splitter UPs and the weather station(s) must
be connected with each other via the RS485 line and
the earth line. One terminating resistor (120 Ω) must be
installed manually on each end of the RS485 line. A valid
protocol can be recognised via the third LED on the
WMS Splitter UP.
The WMS Splitter UP has two serial numbers, one for WMS
and one for the RS485 range.
The transmission of weather data only takes place
after the RS485 side has been successfully con-
nected.
Central command
The master splitter is equipped with a switch input X3.
If this input is activated, the central command Scene is
sent. In order to close the scene again, the input must be
reopened.
The position of the central command can be set
via the WMS studio pro.
Deleting the WMS Splitter UP from the network
(restoring the factory settings)
If the WMS Splitter UP is deleted, no further wea-
ther data is sent to the network.
ATTENTION, the control modes no longer function.
