Setup
Setting up the CO2 Detector C1
- Power On: Connect the provided USB power cable to the C1 device and a suitable USB power adapter (not included) or a USB port. Alternatively, insert 3 AAA batteries (not included) into the battery compartment.
- Initial Warm-up: Upon powering on, the device will undergo a brief warm-up period (approximately 30 seconds) before displaying readings.
- Calibration (Optional): For optimal accuracy, it is recommended to perform a calibration in a well-ventilated outdoor environment.
- Take the C1 device outdoors to an area with fresh air.
- Press and hold the "CAL" button (refer to device diagram for button location) for 3-5 seconds until the display shows "CAL".
- Allow the device to calibrate for approximately 5-10 minutes. The display will return to normal readings once calibration is complete.
- Time and Date Setting: Use the "TIME" and "SET" buttons to adjust the time and date as needed.
Setting up the Indoor Outdoor Thermometer Q8
- Main Unit Power: Insert 2 AAA batteries (not included) into the battery compartment of the Q8 main unit.
- Outdoor Sensor Power: Insert 2 AAA batteries (not included) into the battery compartment of the outdoor sensor.
- Pairing the Sensor:
- Place the main unit and the outdoor sensor close to each other.
- The main unit will automatically search for the outdoor sensor. The outdoor temperature/humidity display area will flash.
- If pairing is successful, the outdoor readings will appear on the main unit's display. If not, press the "CHANNEL" button on the main unit to manually search for the sensor.
- Channel Selection: The outdoor sensor has a channel switch (1, 2, or 3). Ensure the channel selected on the sensor matches the channel displayed on the main unit for proper communication. The Q8 main unit can connect to up to three sensors (only one sensor is included).
- Placement:
- Place the main unit indoors in a central location, away from direct sunlight or heat sources.
- Mount the outdoor sensor in a shaded, dry location outdoors, protected from direct rain and sunlight, to ensure accurate readings.
Operating Instructions
CO2 Detector C1 Operation
- Reading Display: The main screen displays CO2 concentration in PPM, indoor temperature (℉ or ℃), indoor humidity (%), and current time/date.
- CO2 Level Indicator: The display features a color-coded indicator (e.g., green for good, yellow for moderate, red for poor) to quickly assess air quality based on CO2 levels.
- Data Refresh:
- When powered by USB, data refreshes approximately every 6 seconds.
- When powered by batteries, data can be refreshed by pressing the "DETECT" button to conserve power.

- Temperature Unit Switch: Press the "C/F" button to switch between Celsius (℃) and Fahrenheit (℉).
- Alarm Function: The C1 may feature an adjustable CO2 alarm. Refer to the specific button layout on your device for alarm setting instructions.
Indoor Outdoor Thermometer Q8 Operation
- Reading Display: The main unit displays indoor temperature (℉ or ℃), indoor humidity (%), outdoor temperature (℉ or ℃), and outdoor humidity (%).
- Temperature Unit Switch: Press the "C/F" button on the main unit to switch between Celsius (℃) and Fahrenheit (℉).
- Channel Switching: If you have multiple outdoor sensors, press the "CHANNEL" button on the main unit to cycle through the readings from different sensors (CH1, CH2, CH3).
- MAX/MIN Records: Press the "MAX/MIN" button to view the maximum and minimum temperature and humidity readings recorded since the last reset. Press again to clear the records.
- Humidity Level Indicator: The display may show comfort levels (DRY, GOOD, HUMID) based on indoor humidity.
Maintenance
- Cleaning: Wipe the devices with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: Replace batteries in both the Q8 main unit and the outdoor sensor when the low battery indicator appears on the display. For the C1, replace batteries if using battery power and the display dims or stops functioning.
- Storage: If storing the devices for an extended period, remove all batteries to prevent leakage. Store in a cool, dry place.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on device. | Low or dead batteries; incorrect battery insertion; no power for C1. | Replace batteries, ensure correct polarity. For C1, check USB connection. |
| Outdoor readings not displayed on Q8. | Sensor out of range; sensor batteries low; incorrect channel; interference. | Move sensor closer to main unit; replace sensor batteries; ensure sensor and main unit are on the same channel; reduce interference sources. |
| Inaccurate CO2 readings on C1. | Needs calibration; sensor obstruction. | Perform outdoor calibration as described in the Setup section. Ensure sensor vents are clear. |
| Readings fluctuating excessively. | Device exposed to drafts, direct sunlight, or rapid temperature changes. | Relocate the device to a stable environment. |
