Installation

Plug in the enclosed 5V-1.2A AC/DC adaptor to an AC wall outlet and then the DC jack of the USB cable to the back of your air quality monitor. Connect the free ends of the USB cable with AC/DC power adapter with each other. The display will come on with the mood light. Your CO 2 reading flashes with “----” PPM. The relevant CO 2

data will be displayed in around 2 minutes. It takes around 30 minutes to have all the CO_2 readings stabilized.

If the AC power is interrupted, the monitor does not function, the display turned off. The settings of your unit will be kept by the internal memory chip so your monitor will function again after the AC power resumes.

Ventilation recommendation on the basis of CO2 concentration in the air Your CO2 monitor measures and displays the CO2 in PPM with color ventilation recommendations :-

CO2value	Chart display
over 2000 PPM
1501-2000 PPM
1001-1500 PPM
601 – 1000 PPM
400-600 PPM

The “con flashes when the current CO2 value exceeds 2000 ppm.

It also shows the ventilation icon " if ventilation is recommended and needed.

To Set High-Low Alert of CO2

1) Press and hold the CO₂ ALERT button, the CO2 digits "400" (default) flash and ▼ + -

appears. Press the MEM or the CAL button to adjust the low alert level of CO2. Press once to adjust +/- 10 PPM. Press and hold the button to accelerate setting in fast speed. The lowest alert level is 400 PPM.

Press once to adjust +/- 10 PPM. Press and hold the button to accelerate setting in fast speed. The highest CO2 alert level is 5000 PPM.

3) Press the button to confirm.

Note: your monitor will store your settings and exit the alert set mode when no key is pressed in approximate 10 seconds.

When the measured CO2 reaches the set high / low alert level, the related ▲ or ▼ icon appears and flashes to remind you.

Use the audible CO₂ alarm (for high alert)

- Press the button once to turn on the CO2 alarm. When the alarm is on, the icon appears on the display.

- When the measured CO2 reaches the set high alert level, both the ▲ and 🔒 icons flash and an audible beep sound will be given continuously. The beep sound will accelerate when the measured CO2 level exceeds more over the set alert level.

If this happens, please open the windows, adjust the air ventilation and avoid too many people gathering together to improve the air quality of your environment.

- Press the button to disable the CO2 voice alarm. remains flashing if CO2 exceeds the set high alert.

To Recall the Maximum, Minimum Value Memory

- Press the MEM button one at a time to view the maximum => minimum => 15 mins average => 8 hrs average record of the CO2 (MAX con appears when max or min record displayed).

- When the Max / Min reading is being displayed, press and hold the MEM button to reset all records (all digits on the display become “----”) and your monitor will start to store data for the next 24-hour period.

Note :

You need to power on your monitor for at least 15 minutes/ 8 hours to display the relevant last 15-minute/ 8 hours of CO2 level

Calibrate the CO_2 sensor

This monitor is factory calibrated to a 400 PPM CO _2 standard concentration.

Caution:

Do not calibrate the monitor in an environment of unknown CO_2 concentration.

Automatic baseline calibration

Your monitor is equipped with a smart chip so that it will automatically calibrate itself to reduce the drift of the CO2 sensor for long time usage. It will calibrate itself automatically at the minimum CO2 reading detected during 7 days of continuous monitoring.

Note: make sure the place you put your monitor at is well ventilated (with a CO_2 level near 400 PPM) for at least an hour or so everyday, or you move the monitor to such a well ventilated room for an hour or so everyday to perform Automatic Baseline Calibration.

Manual calibration of the CO₂ sensor

It is recommended to undergo manual calibration performed by a qualified laboratory every 12 months.

• Place your CO 2 monitor in a 400 PPM calibration chamber or a room with as close to 400 PPM as possible. Power it on and wait for 1-2 minutes until the
  first CO2 reading is displayed. Then press and hold the CAL button until “CAL” flashes as below.
• In around 20 minutes, the blinking will stop and the calibration is completed. Your CO _2 monitor will return to normal display mode.
• To stop the manual calibration anytime, press the button once.

Adjusting the display and mood light brightness

Press the DIMMER one at a time to adjust the brightness of the display and mood night (if mood light is on) from High-Middle-Low.

Turning on/ off the mood light

Press the button once at a time to turn on or off the mood light (factory setting is mood light on).

There are 4 colors of mood light (green, light green, orange and red), that each match the indicating icons of the air quality level on the display.

Troubleshooting

No display or functions

Check the AC/DC adaptor is properly connected.

Response time

Ensure the air flow channels at the back of the monitor are not blocked or covered.

CO _2 reading shows “Err”

The CO_2 sensor is not working properly. Unplug the AC/DC adapter (C6) for 10 seconds to insert it to your monitor again.

Care and maintenance

• Place your monitor on a stable surface, away from sources of direct sunlight or excessive heat or moisture.
• Clean your monitor with a soft cloth moistened only with mild soap and water. Stronger agents such as Benzine, thinner or similar materials can damage the surface of the item. Make sure the monitor is unplugged before cleaning.
• Do not open the back case or tamper with any components of this monitor.
• Do not plug in any other AC/AC or AC/DC adaptor with incorrect specifications or voltage.

CO _2 levels and guidelines

Below are some CO_2 reference levels in general:

400\~600 ppm Background (normal) outdoor air level.

600\~1,000 ppm Typical level for occupied spaces with good air exchange.

1,000 \~1,500 ppm Start ventilation of the room.
1,500\~2,000 ppm Level associated with complaints of drowsiness and poor air. Ventilation recommended!
2,000\~5,000 ppm Level associated with headaches, sleepiness, and stagnant, stale, stuffy air. Poor concentration, loss of attention, increased heart rate and slight nausea may also be present. Ventilation strongly recommended!

5,000 ppm Exposure may lead to serious oxygen deprivation

resulting in permanent brain damage, coma, and death. Requires immediate ventilation!
