General Introduction
Indoor Air Quality (IAQ) is measure for the quality of air in interiors, the comfortable indoor environmental quality can make people feel fresh, work efficiency and good for the health. The CO2 concentration is the important factor of good indoor air quality. People breath in oxygen and breath out CO2, nowadays people often close the windows to avoid noise and enjoy the comfort living and working environment provided by air-conditioning systems, which results in the fact that the indoor concentration of CO2 is far higher than outdoor average. With the high CO2 concentration and non- proper ventilation, people will feel headaches, dull, drowsiness, lose of concentration and correspond to the high levels of dust, chemicals and bacteria in the air.

Customizing Settings
  When the power has been connected, The ZG1163R CO2 monitor will begin to work. In order to meet your personal requirements, it is advisable to set up the customizing parameters.

Temperature (ºC/ºF) RH and Ventilation Rate:

1.Press up/down to select the temperature, RH and ventilation rate modes.
2.When pressing up button, the LCD display sequence is Temp ºC -> Temp ºF -> Vent Rate lps -> Vent Rate
 cfm/p. When pressing down button, The LCD display sequence is reverse.
Temp ºC refers to Temperature in Celsius; Temp ºF refers to Temperature in Fahrenheit. Vent Rate lps
refers to Liter Per Second Per Person; Vent Rate cfm/p refers to Cubic Feet Per Minute Per Person

Using the MUTE function:

1.Press Mode, the speaker icon flashes simultaneously.
2.Press Enter, use up/down to select the on/off.
3.Press Enter again to save the data.
Note: The factory setting with alarm is buzzer off, user can set the alarm on/off under MUTE function.

Using the ALTI mode:

1.Press Mode,the ALTI icon flashes.
2.Press Enter, ALTI shows on the display, press the mode button to alter between the m( meter) and ft(feet).
3.Adjust altitude (step=100m/500ft) by up/down button.
4.Press Enter again to save the data.

Setting the ALARM 1 level:


1.Press Mode, the ALARM 1 icon flashes.
2.Press Enter. Using the Up/Down to set the parameter, the default ALARM 1 is 800 ppm.
3.Press Enter again to save the data.


1)When CO2 Alarm level is ≧1,000 ppm, the interval is ±100ppm, when the CO2 Alarm level is <1,000
  ppm, the interval is ±50 ppm
2) After setting with new alarm level parameter, the green LED will light when CO2 concentration below
 the alarm 1 level.

Setting the ALARM 2 level:

1.Press Mode, the ALARM 2 icon flashes.
2.Press Enter. Using the Up/Down to set the parameter, the default ALARM 2 is 1200 ppm.
3.Press Enter again to save the data.


1) When CO2 Alarm level is ≧1,000 ppm, the interval is ±100ppm, when the CO2 Alarm level is <1,000
  ppm, the interval is ±50 ppm.
2) After setting with new alarm level parameter, the green LED will light when CO2 concentration below
 the alarm1 level. The red LED will light when CO2 concentration exceeds the alarm 2 level, the yellow
 LED will light when CO2 concentration is between the alarm1 level and the alarm 2 level.

Using the OUTSIDE mode:

1.Press Mode, the OUTSIDE icon flashes.
2.Press Enter, shows OUTSIDE, CO2 and ppm flashes. Press the Up/Down to adjust the data.
3.Press Enter to save the setting. After the modification, the VENT Rate will change.


Ventilation rate represents how much air is introduced into the indoor space from outside. Low numbers
indicate low ventilation rates and potentially poor air quality.
High levels indicate excessive ventilation and potential excessive energy usage. To obtain an accurate
measurement, reading should be taken 2~3 hours after occupancy has stabilized in a space or at a peak
in daily CO2 concentrations. For indoor air quality control, CO2 value is an indicator of ventilation rate.
400ppm (Parts Per Million) is the default CO2 concentration outside according to ASHRAE: American
Society of Heating, Refrigeration and Air conditioning Engineers.

Using the CALI (calibration) mode:

1.Press Mode, the CALI icon flashes.
2.Press Enter, the CALI icon on the display. Adjust the CO2 reading by Up/Down button.
3.Press Mode for more than 10sec,CALIBRATING flashes. Calibration will be done automatically after about 3
minute and the LCD will display “Pass” or “Fail.” If it shows “Fail,” please try again.

Using the LOG mode:

1.Press Mode, the LOG icon flashes.
2.Press Enter, CO2 reading and Temperature show on the LCD.
3.Press Up/Down to page up/down the reading.


With the Built-in Datalogger, ZG1163R can provide the past CO2, temperature and RH reading within the
past 24 hours. The log interval is 30 minutes per data. ZG1163R is connected with power and used for
the first time. If the working time is more than 30 minutes, ZG1163R will have CO2, RH and temperature
reading in datalogger, if the working time is less than 30 minutes, the LCD will display “NULL” while
using the LOG function.

Using the MAX MIN mode:

1.Press Mode, the MAX MIN icon flashes.
2.Press Enter, the MAX and MIN CO2 reading alternatively shows.
3.Press Down and the “CLr” will flash on the LCD. Press Enter to CLEAR the MAX and MIN record.


With the Built-in MAX MIN mode, ZG1163R can provide the Maximum and Minimum CO2 readings since
the device has last been turned on. If users press up/down to clear the MAX and MIN CO2 reading record,
ZG1163R will provide the new MAX and MIN CO2 reading from that time.

Using the “RcFS” Mode:

1.Press Mode, the RcFS icon flashes.
2.Press Enter, the icon “no” shows on the LCD, Press the Up/Down to select the no/yes.
3.After selecting, press Enter to save the setting.


If the user sets the data or calibrates the ZG1163R incorrectly, use the RcFS (recover the factory Setting)

to come back the default factory setting.
