"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. -
Page 5: Safety Instructions
Sensor Splitter 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. - Page 6 Sensor Splitter The following pictograms and symbols may be affixed to the control itself or to the connected devices, alerting you to potential danger: WARNING Warning against dangerous electrical voltage! CAUTION Component damage due to electrostatic discharge! NTTE The term NTTE marks important information and helpful tips.

Page 7: Intended Use
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. -

Page 10: Installation
Sensor Splitter 3 Installation This chapter will tell you where and how the individual components must be installed. WARNING Dangerous situations and malfunctions are possible! The device and its auEiliary components may only be operated when installed and at the specified installation locations. -
Page 11: Mounting The Device
The minimum distance between the terminals and another object equals 10 mm. The devices can be mounted by simply clipping them onto the DIN rail. Fig. 2 Sensor splitter in a 3 MW DIN rail-mounted housing 54 mm 3 TE 60 mm Fig. -
Page 12: Connection
230 V AC lines (power lines) should not be routed between the DIN rail and rear wall but to one side at as great a distance as possible. The external +24-V voltage provided by the sensor splitter is exclusively in- tended for supplying a connected weather station. If other weather stations are connected, they need to be supplied by a separate power supply unit. -
Page 13: Bus Lines
Sensor Splitter 4.2 Bus lines CAUTION Only make changes to the bus wiring while the unit is in a de-energised state. Several basic principles must be observed to ensure fault-free bus communi- cation. Do not accidentally swap the connections of the bus of the central control... -
Page 14: Hardware Settings On The Sensor Splitter
This sensor splitter must be set as a MASTER using the encoding switches on the board of the sensor splitter. By default, all encoding switches are in the OFF posi- tion. - Page 15 Sensor Splitter 2005613_a•en•2017-09-01 We reserve the right to carry out improvements...

Page 18: Connecting The Wisotronic
The sensor splitter to which the weather station multisense is connected must be supplied via a separate power supply unit. If possible, always connect the weather station to the sensor splitter that is acting as the MASTER. Provide separate on-site fuse protection for the sepa- rate power supply unit. - Page 19 Sensor Splitter Fig. 9 Connection example for Wisotronic 2005613_a•en•2017-09-01 We reserve the right to carry out improvements...

Fig. 11. Please note the following special features when connecting the unit: The sensor splitter to which the weather station is connected must be sup- plied via a separate power supply unit. If possible, always connect the weather station to the sensor splitter that is acting as the MASTER. - Page 21 Sensor Splitter Fig. 11 Connection example for WAREMA climatronic ® 2005613_a•en•2017-09-01 We reserve the right to carry out improvements...

Page 22: Connecting A Separate Power Supply Unit
NTTE The sensor splitter MASTER and the weather stations should always have their own power supply unit. Providing a separate power supply unit with its own on-site fuse protection ensures that weather data will always be sent to the sensor bus. -

Page 24: Connecting Multiple Weather Stations
Total length of the RS485 bus: maximum 1200 m. The bus voltage must be at least 20 V at each device. The sensor splitter MASTER must be supplied via a separate power supply unit. The maximum line length between the weather station and the sensor splitter MASTER is 200 m. -
Page 25: Commissioning
NTTE The power supply can also be switched on simultaneously for the entire unit. If the power supply of the weather station and sensor splitter MASTER is switched on later, it will not be possible to correctly commission the unit. -
Page 26: Procedure For Warema Climatronic
Separate the bus line in such a way that the bus of the weather station (sen- sor bus) is only connected with the bus of the first climatronic (climabus 1) (Fig. 15, 2 ). The sensor splitter is completely separated from the bus and the bus lines are directly connected to each other. - Page 27 Sensor Splitter Weather station Sensor bus Sensor splitter 1 Sensor splitter 2 Output state or MASTER SLAVE final state of bus wiring BK RD BK RD climabus 1 climabus 2 climatronic 1 climatronic 2 = Terminating resistor Weather station Sensor bus...
