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.
 
 
Features & Display Features and Modes

  concentration.
Three different LED display show the current Indoor Air Quality situation.
  (HVAC/ GreenHouse Mode)
Linear analog output (0~10V Voltage, 4~20mA Current) and Relay output based
  on CO2 Level.
Reliable Sensor provides long-term calibration stability.
The visual and audible alarm function can be adjustable by user.
Mounting bracket with terminal block provides quick easy installation.

Cleaning --- disconnect the power before clean. Use a damp cloth; do not use the liquid cleaning agent, such
                        as benzene, thinner or aerosols.
2.
Repair --- Do not attempt to repair the product or modify the circuitry by yourself. Please contact with 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 when it’s
                            necessary.
4.
Air diffusion --- The ventilation slots on the housing are designed for CO2 diffusion, so these ventilation slots
                              should not be blocked.
 
 
Installation Step
 
 
Step 1 Step 2 Step 3
Step 4 Step 5
Step 1-3: Remove the back cover by releasing the top screw.
Step4: Secure the back cover(mounting plate) to the junction box on the wall. And make sure the wire
     connections.
Step 5: Finish the installation by mounting the controller on the back cover.

Customizing Settings
 
 
 

When the power has been connected, The CO2 monitor will begin to work. In order to meet you personal requirement, it is advisable to set up the customizing parameter. Warm Up: It lasts approximately 1min before WARM UP disappears; all MODE functions will not response during warm up.

Mute Mode:

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

Setting the ALARM 1 level:

 
1.Press MODE, until the ALARM 1 icon flashes.
2.Press ENTER. Using the Up/Down to set the parameter. The default alarm 1 is 800 ppm (HVAC), 1000ppm (GreenHouse).
3.Press ENTER again to save the data.

Setting the ALARM 2 level:

 
1.Press MODE, until the ALARM 2 icon flashes.
2.Press ENTER. Using the Up/Down to set the parameter. The default alarm 2 is 1200ppm (HVAC), 600ppm (GreenHouse).
3.Press ENTER again to save the data.
Note: The factory setting with alarm is buzzer off; user can set the alarm on/off according to alarm function instruction.

Setting the Calibration mode:

 
1.Press the MODE. Until the CALI icon flashes.
2.Press the ENTER, CALI show on the display.
3.Adjust the display to the required CO2 value (user can pump the CO2 gas or use outside natural gas while calibrating) by up/down button.
4.Press the MODE morn than 10 sec, CALI flashes. Calibration will be done automatically after 10 minutes and LCD will display “Pass” or “Fail”. If it shows “fails”, please try again.

Setting the Alti Mode:

 
1.Press MODE, until the ALTI icon flashes.
2.Press ENTER, ALTI show on the display meter.
3.Adjust altitude by up/down button to the actual location level.
4.Press ENTER again to save the data.

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 RcFS (Recover the factory Setting) to come back the factory setting data.
 
 
Advanced Mode
 
 
 

Press the Enter and Up together for about 10 seconds to enter Adv Mode, there will be “lock” and “mode” on the LCD. Remind these setting will change the features of LED /Relay and Analogue output.

Using Lock Icon:

 
1.Press the Enter and Up together for about 10 seconds to enter Adv Mode, there will be “Lock” on the LCD. Press Up or Down, the LCD will show “on” or “off”.
2.If select “off” and press the Enter button, these 4 keys are enable.
3.If select “on” and press the Enter button, these 4 keys are disable (will not response to the user’s action).

HVAC / Green House(GH)Mode:

 
1.Press the Enter and Up together for about 10 seconds to enter Adv Mode, Press Up or Down until appear the “mode”, then press the Enter button, the LCD will show “HVAC” or “gh”.
2.If select “HVAC” and press the Enter button, AL1 will always be less than AL2.
3.If select “gh” and press the Enter button, AL2 will always be less than AL1.
 
 
The CO2 concentration and voltage diagram
 
 
 

(The line① represents CO2 concentration, the line② represents voltage/ current)

1. When select “HVAC”, AL1 <AL2 (HVAC), if CO2 concentration is rising, the voltage/current will increase;
 
2. When select “gh”, AL1>AL2 (gh), if CO2 concentration is rising, the voltage/current will decrease.
 
Remark:
Under Green House Mode, the AL1 must >AL2.
For example: AL1= 900ppm, AL1= 800ppm now, user decrease AL1= 700ppm, AL2 will become 700-Step, (AL2= 600ppm, if step=100ppm; AL1= 680ppm, if step= 20ppm).
