CO2 ppm Sensor Upgrade

The SXC sensor may be upgrade to sense and control CO2 ppm with a precision NDIR type CO2 sensor.

1. Disconnect cables from the sensor.

2. Remove the hanging bracket (1).

3. Take note the orientation of the light sensor on the cover.

4. Remove the two cover screws (2) and lift off the cover.

5. Locate the CO2 headers on the circuit board.

6. Position and install the CO2 sensor module (3) ensuring the sensor is oriented with the correct pin head-

ers. One header is 4-pins and the other is 5-pins.

Installing the sensor backwards will damage the CO2 module.

7. Re-install the top cover and re-connect cables.

Note the light sensor orientation is correct and not backwards.

8. Check to ensure the CO2 reading is now working.

Note correct pin alignment.
