　.our local dealer time or a qualified repairman if the product needs servicing.
3. Calibration--- Please observe the calibration operation to make sure the accuracy for the devices
　 whey necessary.
4. Air circulation---The vents allow the air circulation liquid for measurement of the CO2 concentration
　.and the ventilation and should not be blocked.

Installation Step



Step 1: Release the screw from the device, take the front cover off.
Step 2: Release the four screws from the black cover, take the CO2 board from the black cover.
Step 3: Using the screw to fix the black cover to the current outlet, let the wires come out of the hole.
Ste　3: Please pay attention to the terminal block connection data information.
Step 4: Re-assembling the CO2 board by screw to the black cover.
Step 5: After finishing the terminal block wire connection. Press the front cover to the LCD display,

Wiring Connection

Customizing Settings

When the power has been connected, The ZGw08VRC CO2 monitor will begin to work. In order to meet you personal requirement, it is advisable to set up the customizing parameter.

Setting the alarm function

1.Press the MODE, the speaker icon flashs simultaneously.
2.Press ENTER, use up/down to select the on/off.
3.Press ENTER again to save the setting.

Setting the Calibration mode

1.Press the MODE ,the CALI icon flashs.
2.Press the ENTER ,CALI show on the display.
3.Adjust the display to the ambient CO2 value by up/down button.
4.Press the MODE morn than 10 sec, CALI flashs. Calibration will be done automatically after 5 minutes 4.and LCD will display "Pass" or "Fail". If it shows "“fails", please try again.

Setting the Alarm parameter Mod

1.Press the MODE, the speaker icon flashs simultaneously.
2.Press ENTER. Using the Up/Down to set the parameter.
3.Press the ENTER again to save the data.
Remark: There have AL1 & AL2 when you press the mode. You can set the two different level on your opinion. The resoulation is 100 ppm per times.

Using the ReFactSet Mode

1.Press MODE, The ReFactSet flashs simultaneously.
2.Press ENTER,Using the Up/Down to select the No/Yes
3.After the slecting,Press the ENTER to save the changes.
Remark: If the user setting the data or calibrate the sensor wrongly. You can use the ReFactSet (Recover the factory Setting) to come back the factory setting data.

Calibration & Warranty

Notice: Before calibrating ,you need standard gas or semi-standard gas, there are 3 methods to get standard gas.

Method A: use CO2 in office/building
-Use two Meters (One is the device for calibration. The other one is a calibrated (new) one.
-Use ambient room gas for calibration in office, waiting at least 10min,until the CO2 reading doesn't change (notice: user must not breathe toward the ZGw08VRC, CO2 from the user will affect the reading of ZGw08VRC)
-Use the reading of the new device as the standard.
-Calibrate the device by the Cali Mode instruction.

Method B: use CO2 outsides
-Use ambient room gas for calibration outsides, waiting at least 10min, until the CO2 reading doesn't change ( notice: user must not breathe toward the ZGw08VRC, CO2 from the user will affect the reading of ZGw08VRC)
-Use 380~420ppm as the standard reading.
-Calibrate the device by the Cali Mode instruction.

Method C: use standard CO2 in the bottle
- Pump the standard CO2 gas(0~1000ppm, flux = 0.1~0.2 liter/min) into the ZGw08VRC from the Gas Entry Hole (top left corner ) waiting about 2~3min.
- Calibrate the device by the Cali Mode instruction.
Warranty: 18 months parts and labor.
