NTROL 3000 Manual   

 

AIRCO2NTROL 3000 is a portable, accurate handheld CO

2

 monitor. In addition to measuring the CO

2

 concentration, this device can also 

measure the ambient temperature. It uses NDIR technology to improve the long term stability.   

 

Features: 

V

The built-in Data logger

 can store 48 sets of CO

2

 and temperature in the past 24 hours; one log per 30 minutes. 

V

Max/Min mode

 can record the maximum and minimum concentration of CO

2

 since the device has been last turned on. 

V

The Alarm mode

 will sound at 1000 PPM, the ASHRAE limit. The Alarm can be turned off. 

V

The RCFS Mode

 can recover the original factory settings after the CO

2

 device has been recalibrated, altered, or damaged. 

 

 

 

 
 

 

 

 

 

 

MODE FUNCTIONS 

There are several Modes which we can adjust the setting parameters. These modes are Alti Mode,Alarm Mode, Outside Mode, Ucal Mode, 

Datalogger Mode, MaxMin Mode and rcFS Mode in sequence. 

ALTI 

Compensate the pressure changes with appropriate altitude of location when measure.

 

 

ALARM 

Alarm while CO

2

 concentration exceed one threshold, Alarm sound can be on or off.

 

 

OUTSIDE 

Modify the outside CO

2

 concentration, for defining the ventilation rate.

 

 

CALI 

Calibrate the sensor while the reading deviates from the actual CO

2

 concentration.

 

 

DATALOGGER 

Show the past CO

2

 and Temperature records in the past 24 hours.

 

 

MaxMin 

Show the Max and Min CO

2

 reading before being cleared or powered off after PowerOn.

 

 

rcFS 

Recover the factory setting, if the device cannot show accurate reading.

 

 

 

OPERATION INSTRUCTIONS 

 

 

PowerOn

 

Press Power button(

) to turn on the device after placing 4 AA batteries into the battery holder or AC adapter plug into the DC socket . 

Once power on, CO

2

 reading will show after 15 seconds of warm up.

WarmUp

 

It lasts approximately 1min before WARMUP disappears; all the functions will not response during warm up. 

 

UserMode

 

   

After warm up, the device will stabilize and display the normal CO

2

 Reading (Upper Display)- remain visible at all times. 

 

 

Temp and Ventilation Rates (Lower Display)   

The Up/Down button(

/

) allows you to scroll through the Temperature and Ventilation Modes.When pressing the Up button,the   

lower display will go through the following sequence: TempºC -> TempºF -> Vent Rate lps -> Vent Rate cfm/p 

 

*

Note: lps refers to Liter Per Second Per Person; cfm/p refers to Cubic Feet Per Minute Per Person 

 

 

Operation of Mode Adjustment 

 

 
1.ALTI Mode:                                                                                                                         

1.1. Press the Mode Button(

), ALTI flashs 

1.2. Press Mode(

) to alter between m(meters) and ft(feet) . 

1.3. Press Up/Down(

/

) to adjust the altitude (Step=100m/500ft) 

1.4. Press the Enter Button(

), save or leave the ALTI Mode, return to UserMode 

2.ALARM Mode 

2.1

.

 Adjust the alarm level

 

2.1.1. Press the Mode button (

), until ALARM flashs

 

2.1.2. Press Enter Button(

), “CO2” icon flashs. 

2.1.3. Press Up/Down(

/

) to adjust the alarm level (

1,000 ppm, interval is 

±

100ppm; 

1,000 ppm, interval is 

±

2.2.3. Press Up/Down(

/

) to turn on/off the ALARM, 

2.2.4. Press the Enter(

), save the setting and return to UserMode. 

3.OUTSIDE Mode 

 

** Note:Ventilation Rate 

Ventilate rate represents how much air is introduced into the indoor space from the outside. Low values 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 CO

2

 concentrations

In 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) 

 
3.1. Press the Mode button(

) ,until OUTSIDE flashs 

3.2. Press Enter(

), show OUTSIDE, CO

2

 and PPM flash 

Press Up/Down(

/

) to adjust the reading     

3.3. Press the Enter(

), save the setting and return to UserMode 

After modification, the VENT Rate will change 

 

 
4. CALI Mode

 

The CO

2

 monitor has been calibrated in the factory and should recalibrate every 12 months with a specified concentration of CO

2

.Sensor drift 

usually occurs in linearity. Please follow below steps. 

4.1. If battery icon shows low power, please replace new batteries or use AC adapter   
4.2. Press the Mode button(

), until CALI flashs 

4.3. Press Enter(

), CALI shows on display   

4.4. Adjust the lower display to ambient CO

value by Up/Down (

/

) Button.
