Sensor Splitter
1 Features
The sensor splitter is used to connect
multiple WAREMA climatronic®units to 1 to 3 weather stations or Sensor
Interfaces
multiple Wisotronic 1/2/3/4-channel to one weather station multisense
Thus, separate sensors are not needed for each central control unit. For ex-
ample, if there is one central control unit per storey in a building, all central
control units can be supplied with the necessary weather data from a single
weather station.
The measuring values are actively requested from the connected weather
stations via the sensor splitter. All other sensor splitters on the bus merely
need to "listen".
The devices can be mutually connected via a separate RS485 bus.
The sensor splitter makes 24 V DC/250 mA available on the bus on the sen-
sor side (sufficient for one weather station). If multiple weather stations are
connected, they need to be supplied by a separate power supply unit.

2 Safety instructions
We developed and tested the sensor splitter in compliance with the basic
safety requirements.
Residual risks nevertheless remain!
 For this reason, please read these instructions before commissioning and
operating the control.
 It is very important to adhere to the safety information listed here and the
warning information in these instructions.

Sensor Splitter
2.2 Intended use
The sensor splitter is an electronic device that is used to connect up to three
weather stations or Sensor Interfaces to multiple WAREMA climatronic®con-
trol panels or to connect one weather station multisense to multiple Wisotron-
ic control panels at the same time. The device is designed for interior instal-
lation. The approval of the manufacturer must be obtained for uses outside of
the purposes listed here.
WARNING
The consequences of unintended use may include personal injuries of the
operator or of third parties as well as property damages to the unit itself,
connected devices or moveable mechanical parts of the entire system.
 Therefore, use our product only as intended.
2.3 Targeted reader group
These instructions address persons mounting, wiring or connecting the sen-
sor splitter and all necessary parts. Please contact your specialist dealer if
you need additional information.
WARNING
Mounting, connection, commissioning or operation by insufficiently
qualified and knowledgeable persons may cause serious damage to the
system or even personal injuries.
 Mounting and commissioning may therefore only be performed by properly
trained qualified technicians. These specialists must be able to recognise
sources of danger that may be caused by the mechanical, electrical or elec-
tronic equipment.
 Persons mounting or connecting the device must know and have understood
the content of these instructions.
2.4 Retrofitting and
modifications
We designed and built the device with reliability and safety in mind. All re-
quired settings are made when the unit is first commissioned. Modifications
to the system parameters are therefore only required when the characteristics
of the system need to be adjusted, changes are made to the sensor equip-
ment or the device itself is replaced.
WARNING
Retrofitting and modifications may impact the safety of the system or
reduce its effectiveness. Possible consequences may include death,
serious or light injuries, property damage or environmental damage.

2.5 Mounting, connection
and repairs
DANGER
Danger to life through electrical voltage!
 Connecting, maintenance or repair work on the electrical parts of the entire
system must only be performed when power to the system has been cut off,
unless otherwise described. The unit must be sufficiently secured against un-
authorised and inadvertent reactivation.
 If measuring or testing activities need to be carried out on the active unit, ex-
isting safety and accident prevention regulations must be observed under all
circumstances.
 Make sure to always use suitable electrical tools.
WARNING
States of danger, malfunctions and property damage to the unit may arise
from improperly executed mounting, connection, repair or maintenance
work.
 Such work may only be carried out by the service department or by author-
ised qualified specialists.
 Only use such spare/replacement parts for maintenance or repair work as
have been approved by the manufacturer of the unit.
WARNING
Dangerous situations, malfunctions and property damage to the unit may
result if connections are disconnected during operation! All connections
are required for proper operation of the device.
 Therefore, switch off the entire system before attaching or detaching connect-
ing lines.

2.6 Additional documents
When performing the installation, follow the separate instructions of the com-
ponents being connected.
2.7 Maintenance
There are no parts within the device that require maintenance.
2.8 Liability
Failure to comply with the product information in these instructions and use
of the device in a manner that contravenes its intended use and purpose
may result in the manufacturer refusing to honour warranty claims for prod-
uct damage. In this case, liability for secondary harm to persons or damage
to property will also be excluded. Follow the instructions in the operating
instructions of your sun shading system. The automatic or manual operation
of the sun shading system when iced over as well as using the sun shading
system during severe weather may cause damage and must be prevented by
the user by taking suitable precautions.

 First determine where the individual components are to be installed. Use the
instructions given in Chapter4.1 on page 12.
 Then determine which cables are required to connect the components with
one another. Use the instructions given in Chapter5 on page 16.
 Lay the required lines. It is advisable to use conduits.
 Install and wire the individual components.
 Check the wiring before switching on the operating voltage.
 Then commission the unit as described in Chapter 6 on page 25.
 Check that the connected central control units and sensors are functioning
properly:
