T Disp IMPORTANT WARNINGS • Only qualified trade installers should install this product • This product is not intended for life-safety applications • Do not install in hazardous or classified locations • The installer is responsible for all applicable codes • De-energize power supply prior to installation or service PRODUCT APPLICATION LIMITATION: Senva products are not designed for life or safety applications. Senva products are not intended for use in critical applications such as nuclear facilities, human implantable device or life support. Senva is not liable, in whole or in part, for any claims or damages arising from such uses. FEATURES The TotalSense series design allows customization for a sensor that meets project requirements for monitoring temperature, carbon dioxide (CO2), total volatile organic compounds (TVOC), particulate matter (PM), relative humidity (RH). The product can be ordered as a stand-alone CO2, RH, Temp, TVOC, PM sensor as well as almost any combination of sensors. All models come standard with programmable set-point relay and barometric pressure compensation for CO2. Choose the analog version to receive up to three selectable and programmable analog outputs or utilize the communications version to access a myriad of data through Modbus RTU or BACnet MS/TP. To verify the features see the 'Product Identification’ section of the installation manual or use the configuration tool at senvainc.com or scan the QR code on the right. TotalSense Configurator T talSense TM SeriesSETUP - WIRING The following diagrams show terminal locations for each version of the TotalSense. The number of options selected will determine which of the terminals are included on each device. For example, if only one sensor is chosen, only 1 pair of analog terminals will be present. Each device will have 4-8 terminals on the left side, 0-4 on the top, and 0-4 on the right side. Analog Wiring *These terminals may not be populated depending on which model is ordered. Communications Wiring NOTE: A 120 Ω termination resistance may be added in parallel with the RS-485 +/- by moving the very top DIP switch (DIP 1) to the left position. See “DIP Configuration” section for more information. SETUP - ANALOG Switch 1 with two DIP switches will be provided with every device and Switch 2 with an additional 12 DIP switches will be provided with communications devices. The following diagram shows how each setting can be configured using the provided switches. For analog voltage output, select either 0-5V (left) or 0-10V (right) outputs. These analog ranges can be adjusted using the color OLED display. Adjustments made using the OLED display will override this DIP switch setting.

The average air quality is calculated as follows: 1.Each sensor's current reading is rated according to the below thresholds and given an air quality index (AQI). For each sensor, a good rating is given an AQI of 90, fair is given an AQI of 60 and poor is given an AQI of 0. 2.The average air quality is calculated and a total air quality rating is assigned based on the following thresholds. These thresholds can be adjusted using communications or in the "Air Quality Settings" menu from the display. a. Good ≥ 75 b. 55 < Fair < 75 c.

The relay source determines which reading or status will activate the relay. This can be set or adjusted using the display or communications. See 'Display Navigation Guide' or the applicable protocol guide for details. Each source selection has a range listed below. To set turn- on and turn-off thresholds, a percentage of this range can be entered into each corresponding parameter. On display versions, the calculated value will show as the percentage is adjusted. Each time a new source is selected, a default relay threshold will be set based on which technology is chosen. These auto- set values are listed in the table below.

This AI will take 48 hours to acclimate to an environment once installed. The 48 hours will happen after every device reboot. During this time, the sensor will go into "training mode" and will continue to display and output a TVOC value. The staus of the TVOC can be found in the device settings menu. Manual Calibration No manual field calibration is necessary. To maintain accuracy, the TVOC sensor will be required to be exposed to fresh air at least once every 2 days. This can be accomplished by increasing airflow in an area or by opening a window. Scaling: Senva’s TVOC sensor uses an Ethanol reading to determine a raw TVOC value. Additionally, conversion from ppb to µg/m3 uses the molecular weight of Ethanol. To make conversion based on a different gas baseline, user may enter a scaling factor in TVOC Settings on the display or using communications. TROUBLESHOOTING SymptomSolution The device has experienced an error with one of the sensors. Navigate to “Advanced Settings” > "Diagnostics" screen to view more information. All zeros will be displayed if no error is present. See "Display Navigation Guide", or the applicable communications guide or consult factory for troubleshooting help or replacement element. No output Check wiring. Ensure power supply meets requirements. Reading error Verify control panel software is configured for correct output scaling. Verify accuracy of test instrument. Observe installation and calibration guidelines. Verify unit is located away from sources of hot/ cold. Verify sensing element is inserted properly. Perform calibration only if necessary.

Call our toll-free number for live technical support: (866) 660-8864 or feel free to email us at support@senvainc.com CO2 CALIBRATION Automatic Calibration feature: The CO2 sensor will automatically baseline CO2 levels and gradually make adjustments to compensate for sensor drift due to long-term aging of the IR light source. In applications where CO2 levels are continuously elevated, or spaces are occupied day and night, it is recommended to use our dual channel CO2 sensor with automatic calibration disabled. Senva CO2 sensors are factory calibrated to controlled test gases. No field calibration is necessary or recommended. However, to facilitate compliance with job requirements and commissioning procedures, provisions for field calibration are provided: 1. Locate calibration instrument and sensor in close proximity to each other in a controlled environment free of drafts, people, and equipment to reduce influence on CO2 and temperature. 2. Compare output of sensor to calibration instrument, and note difference. (In 0-10V mode/2000ppm range, 1V =200ppm) 3. Refer to the "Setup-Display" section to adjust offset value for CO2 as needed. Factory calibration may be restored by setting offset back to 0. In extreme cases where the sensor module has been damaged, a new module may be installed in the field. Consult factory for replacement module and instructions.
