Page 4: Features
Omnexo Sensor Splitter REG 1 Features The Sensor Splitter is used to connect multiple Omnexo Central control units to 1 to 3 weather stations. 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 construction project, all central control units can be supplied with the necessary weather data from a single weather station. -
Page 5: Safety Instructions
Omnexo Sensor Splitter REG 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 follow the safety instructions listed here and the... - Page 6 Omnexo Sensor Splitter REG The following pictograms and symbols may be affixed to the control unit itself or to the connected devices, alerting you to potential danger: WARNING Warning against dangerous electrical voltage! CAUTION Component damage due to electrostatic discharge! The i symbol denotes important information and helpful tips.

WAREMA Weather station move. If one WAREMA Weather station pro or multiple WAREMA Weather station move are connected, they must be supplied by a separate power supply unit. The specified lines are recommendations. As specified in VDE 0022, the operating company and the installer are responsible for compliance with the regulations put forth by the power supply company and the VDE. -
Page 13: Bus Lines
Omnexo Sensor Splitter REG 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 swap the connections of the bus of the central control unit (terminal X50) with the bus connections for the weather stations (terminal X56). -
Page 14: Hardware Settings On The Sensor Splitter
Omnexo Sensor Splitter REG 4.3 Hardware settings on the Sensor Splitter For the bus communication to operate properly, only one Sensor Splitter may query the measuring values of the connected weather stations. This Sensor Splitter must be set as a MASTER using the encoding switches on the board of the Sensor Splitter. -

Otherwise, long line lengths may result in communication problems. The WAREMA Weather station pro has a 120 Ω terminating resistor that can be connected via a switch (see documentation on the weather station). The WAREMA Weather station move is supplied with a terminating resistor (see documentation for the weather station). - Page 18 Omnexo Sensor Splitter REG Fig. 9 Connection example for Omnexo Central control unit We reserve the right to make technical modifications warema_2063667_alhb_en_v2•2025-05-01...
