CO² level display

Icon	CO² level	Status	Description
****	400 – 600ppm	Outside	Normal outdoor air level.
****	601–1000ppm	Well ventilated, Ideal	Typical level indoors with good

ventilation. 1000 ppm = Recommended maximum level in a closed room. Considered maximum comfort level in many countries.
| 1001–1500ppm| Under ventilated| Poor air quality – requires ventilation. General drowsiness, discomfort and odors.
| 1501–2000ppm| Very poorly ventilated| Danger! You may experience severe headaches, vomiting/nausea, and dizziness within 20 minutes.
****| above 2000ppm| Totally unacceptable| Danger! Headache and dizziness in 5 to 10 minutes. Increased risk for health damage by prolonged exposure.

START THE DEVICE

Connect the ac adaptor to the unit. After switching on, a beep sounds and the room temperature and humidity are shown on the display. During the first 150 seconds, the CO2 display (value and progress bar) starts preheating and will show —-.

CO2 UPPER LIMIT AND LOWER LIMIT EXCEED STANDARD SETTING

Single press [ALARM ON/OFF] to set the Alarm sound on or off.
Press and hold the SET button: CO2 = > CO2 = > RH% = > RH% Single press to view MAX = > MIN = > Current (CO2+TEMP+RH%)

Long press SET button about 2 seconds, CO2/PPM/ shown on, value 400 flashes, press UP or DOWN button to set CO2 lower limit exceed standard value. (lower limit Max value can not be bigger than the upper limit Min value. The Min value is 400, setting unit is 10ppm/set).
Long press SET button about 2 seconds, CO2/PPM/ shown on, value 2000 flashes, press UP and DOWN button to set CO2 upper limit exceed standard value. (upper limit Min value can not be smaller than the lower limit Max value. The Max value is 5000, setting unit is 10ppm/set).

HUMIDITY UPPER LIMIT AND LOWER LIMIT EXCEED STANDARD SETTING

Press SET button, humidity and shown on, humidity value flashes, press UP or DOWN button to adjust lower limit humidity range (lower limit Max value can not be bigger than upper limit Min value, the Min value can be set to 25%, setting unit is 1%/set.
Press SET button, humidity and shown on, humidity value flashes, press UP or DOWN button to adjust upper limit humidity range (upper limit Min value can not be smaller than lower limit Max value. The Max value can be set to 90%, setting unit is 1%/set)

REMARKS

Long press of the UP or DOWN button makes the value run faster.
Lower limit of humidity set as 30%, when humidity lower than 29%, only flashes.

After setting all values, press SET button to save desired value or wait for about 10 seconds.

CO ² ALARM ON/OFF

Default setting is OFF ( symbol is not visible).
Press ALARM ON/OFF button to activate CO2 ALARM function, symbol appears.
When CO2 value goes up to desired upper limit value, alert rings and flashes.

AUTO CALIBRATION

The automatic calibration function means that the sensor will intelligently judge the zero point based on the environmental concentration and calibrate itself after a period of continuous operation (7 days). Calibration takes placeautomatically every 24 hours after the unit has been switched on. The zero point of automatic calibration is 400ppm.

MANUAL CALIBRATION

Find an area with fresh air, CO2 value lower than 400ppm.
Press and hold UP button to enter manual calibration mode. CAL letter flashes. This process takes 20 minutes, after 20 minutes, CAL letter stop to flash and manual calibration is finished.

°C / °F
Default setting is Celsius degree, press DOWN button to change to Fahrenheit.

Press MEM/ button again, MIN value of CO2, temperature, humidity for the last 24 hours is displayed.
Press MEM/ again, the average value for the past 15 minutes of CO2, temperature, humidity is displayed.
Press MEM/ again, the average value for the past 8 hours of CO2, temperature, humidity is displayed.
Press MEM/ button, with 1 short beep sound to exit.

HISTORY CLEANING

Press MEM/ button once to enter any mode, then long press MEM/ to clean all values.
