User Manual for Senva TotalSense Series

Quick Guide

The Senva TotalSense Series air quality sensor features an OLED display for monitoring and configuration. If the screen is locked (indicated by a lock icon), hold the up and down arrows for 5 seconds to unlock. Use the 'enter' button to access the setup menu and navigate through parameters.

Display Navigation and Settings

The display can be customized to show various sensor readings in different corners. To change settings, press 'enter' to access the setup menu, navigate to 'Display', and select the desired corner (Center, Upper Left, Upper Right, Lower Left, Lower Right) to assign a value such as Temp, RH, CO2, TVOC, PM, or Air Quality.

Additional display settings include:

• Screen Lock: Enable or disable screen lock mode (initiates after 60s of inactivity).
• Screen Saver: Choose what to display when inactive or turn the display off.
• Brightness: Adjust brightness for the home screen and screen saver.
• SS Timeout: Set the time before the screen saver activates (1-120 minutes).

Analog Output Configuration

Analog outputs can be configured to output specific sensor readings. Settings include:

• Source: Select the sensor reading to output (e.g., CO2, RH, Temp, TVOC).
• Min/Max Voltage/Current: Define the analog scale (e.g., 0-10V, 4-20mA).
• PID Settings: Configure PID control loop parameters (Proportional, Integral, Derivative coefficients) and PID Invert. Note that PID output controls are only available on Analog output 1 or Analog output 3 for comms+analog devices.

Air Quality and Source Settings

The device allows for detailed configuration of air quality thresholds and individual sensor parameters:

• Air Quality Thresholds: Adjust 'Good-Fair' and 'Fair-Poor' thresholds to define air quality ratings.
• Sensor Enable: Enable or disable specific sensors (Temp, RH, CO2, PM, VOC, CO, Ozone) used in the air quality calculation.
• Source Parameters: Each sensor type (CO2, PM, RH, Temp, TVOC, CO, Ozone, Ambient Light) has specific settings for calibration, offsets, and analog scaling.

Relay and PIR Settings

The relay can be configured to activate based on specific sensor readings:

• Source: Choose the measurement that activates the relay (e.g., CO2, RH, Temp, PIR).
• Thresholds: Set 'Turn On' and 'Turn Off' thresholds based on the sensor's full-scale range.
• Polarity: Select N.O. (Normally Open) or N.C. (Normally Closed) operation.
• PIR Sensitivity: Adjust motion sensor sensitivity (0-100) and occupied delay time.

Diagnostics and Troubleshooting

The device provides diagnostic status codes in binary format to help identify issues. If a status code appears, consult the diagnostic tables in the manual. Common statuses include EEPROM faults, sensor data errors, or sensor not ready states. For most hardware faults, contact the factory.
