When CO
2
Alarm level is
≧
1,000 ppm, the interval is ±100ppm, when the CO
2
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 CO
2
concentration below the alarm1 level. The red LED will light when CO
2
concentration
exceeds the alarm 2 level, the yellow LED will light when CO
2
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, CO
2
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.
*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 CO2 concentrations. For indoor air quality control, CO
2
value is an indicator of ventilation rate. 400ppm (Parts
Per Million) is the default CO
2
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 CO
2
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, LOG icon flashes.
2. Press Enter, CO2 reading and Temperature show on the LCD.
3. Press Up/Down to page up/down the reading.
*Note: With the Built-in Datalogger, ZG1163R can provide the past CO
2
, 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:
*Note: With the Built-in MAX MIN mode, ZG1163R can provide the Maximum and Minimum CO
2
readings since the device has last been turned on. If users press up/down to
clear the MAX and MIN CO
2
reading record, ZG1163R will provide the new MAX and MIN CO
2
reading from that time.
Using the “RcFS” Mode:
*Note: 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.
1. Press Mode, the MAX MIN icon flashes.
2. Press Enter, the MAX and MIN CO
2
reading alternatively shows.
3. Press Down and the “CLr” will flash on the LCD. Press Enter to CLEAR the MAX and MIN record.
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.
