*Note: 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 CO2concentrations. For indoor air quality
control, CO2value is an indicator of ventilation rate. 400ppm (Parts Per Million) is the default CO2concentration 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 CO2reading by Up/Down button.
3. Press Mode for more than 10sec,CALIBRATING flashes. Calibration will be done automatically after about 3 minutes and the LCD will
display “Pass” or “Fail.” If it shows “Fail,” please try again.
Using the LOG mode:
1. Press Mode, LOG icon flashes.
2. Press Enter, CO2reading, Temperature and RH show on the LCD.
3. Press Up/Down to page up/down the reading.
*Note: With the Built-in Datalogger, ZG106R can provide the past CO2and temperature reading within the past 24 hours. The log interval is 30
minutes per data. ZG106R is connected with power and used for the first time. If the working time is more than 30 minutes, ZG106R will have
CO2, RH and temperature reading in data logger, if the working time is less than 30 minutes, the LCD will display “NULL” while using the LOG
function.
Using the MAX MIN mode:
*Note: With the Built-in MAX MIN mode, ZG106R can provide the Maximum and Minimum CO2readings since the device has last been turned on.
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.
*Note: If the user sets the data or calibrates the ZG106R incorrectly, use the RcFS (recover the factory Setting) to come back the default factory
setting.
