To connect the Senseair tSENSE CO2 Temperature and RH Sensor to a BMS system or stand-alone controller, you will need to use the industry standard output signals and communication protocols supported by the sensor. The sensor supports Modbus (MB) or BACnet (BAC) protocol over RS485 for communication.

Here are the steps to connect the sensor:

1. Ensure that you have the necessary power supply for the sensor. It can be powered by 12VDC or 24VAC/DC.

2. Identify the wiring connections on the sensor. The wiring connections include Power, GND, Out1, Out2, Out3, and RS485. These connections can be made using xxxx terminals and can accommodate a maximum wire size of 1.5mm2.

3. Connect the Power and GND wires to the appropriate power source.

4. Connect the Out1, Out2, and Out3 wires to the input terminals of your BMS system or stand-alone controller. These outputs correspond to CO2, Temperature, and Relative Humidity measurements, respectively. The sensor provides a voltage output in the range of 0-10V for each of these measurements.

5. Connect the RS485 wire to the communication port of your BMS system or stand-alone controller. Ensure that you configure the communication settings (Modbus or BACnet) on both the sensor and the controller to establish proper communication.

6. Once the connections are made, you can configure the sensor and the controller to exchange data using the chosen communication protocol. Refer to the sensor's owner's manual for detailed instructions on configuring the communication settings.

By following these steps, you can successfully connect the Senseair tSENSE CO2 Temperature and RH Sensor to a BMS system or stand-alone controller and start receiving the CO2, Temperature, and Relative Humidity measurements in your monitoring or control system.
