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), passive-infrared occupancy sensor (PIR), and ambient light. The product can be ordered as a stand-alone CO2, RH, Temp, TVOC, PM, or PIR sensor as well as almost any combination of sensors. Resistive-set-point sliders and pushbuttons are also available to meet the requirements for any job. All models come standard with programmable set-point relay (except on PM models) 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. Communications version comes standard with ambient light sensing.

FEATURE - AIR QUALITY

If Air Quality is selected to be displayed or if the Air quality Ring option is selected, the device will monitor each CO2, VOC, PM, RH, and Temp sensor present and will display accordingly.
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. Poor  55

PM2.5 TVOC CO2 Temp RH

GOOD (AQI 90) <35 ug/m3 <1000 ug/m3 <1200 PPM 64-79oF 30-60%

FAIR (AQI 60) 35-55 ug/m3 1000-3000 ug/m3 1200-2000 PPM <64oF, >79oF <30%, >60%

POOR (AQI 0) >55ug/m3 >3000 ug/m3 >2000 PPM
<10%, >90%

FEATURE - PIR OCCUPANCY
If PIR option is selected, the PIR (Passive Infrared) sensor will trigger anytime it detects motion. If used to activate the relay or as a communications data point, an off-delay can be programmed using the display or through communications.
The below shows the distance at which the sensor will trigger a motion event based on its adjustable sensitivity rating. A motion event, for the purpose of this graph, is considered the movement of a person or large object.

FEATURE - AIR QUALITY RING
An Air Quality (AQ) Ring may be selected in place of a display. The AQ ring will glow green, yellow, or red according to the detected levels of CO2, PM, VOC, RH, and Temp. See "Feature Air Quality" section for thresholds.
The AQ Ring may be disabled or brightness may be adjusted if the communications model is selected. Additionally, it may be set to only display yellow or red when air quality has degraded to fair or poor levels. See TotalSense "BACnet/Modbus User Guide" for more information.
AQ Ring will turn on and off at a 5 second interval if a sensing error occurs. See "Troubleshooting" section for information.

FEATURE - SETPOINT RELAY

All TotalSense models come standard with a setpoint relay except those ordered with a PM sensor.

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 turnon 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 autoset values are listed in the table below.

TVOC OPERATION

CO2 CALIBRATION

Training Mode The TVOC sensor has artificial intelligence (AI) that allows it to sense and understand different environments. This AI may take up to 7 days to acclimate to an environment once installed. For this reason, a TVOC reading is not included in the Air Quality calculation until it has been powered for 7 days.
During this time, the sensor will go into "training mode" and will not display or output a TVOC value. Instead, the display will show "Training days" where "X" is how many days the device has been in training mode and 7 days is the expected duration. Once it reaches 7 days, a reading will be shown. Using communications, the TVOC reading will show a countdown from -7 to 0 days; once it hits zero the device will switch into normal operation.

45%RH 72 oF

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.

Device shown is in TVOC training mode.
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 10 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 µg/m3 uses the molecular weight of Ethanol. To scale based on a different gas baseline, user may enter a scaling factor in TVOC Settings on the display or using communications.

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.
