Page 3: Material Supplied
MATERIAL SUPPLIED This package contains: Meter (controller+sensing) Operation manual Paper box Screws and tape POWER SUPPLY The meter is AC100~240VAC powered by AC100~240 VAC directly. The power plug is a USA piggyback plug type so you can plug in the device you want to control. For customers who must use EU or UK type plug, the power coil... -
Page 4: Safety Fuse
SAFETY FUSE The meter is powered by AC100~240 VAC directly and provide power through piggyback socket or EU/UK type socket to drive CO2 generator or ventilation. To avoid the damage by power overload , a 3kA@300VAC fuse is installed in meter. - Page 5 LCD DISPLY CO Chart CO trend in graphic Max of displayed chart Min of displayed chart Buzzer Beeper alarm on/off indicator Zone one value for relay control Center enter value for relay control urrent CO value Time scale Chart time scale.

- Page 6 TAKING MEASUREMENT The meter starts taking measurement after power on and updates readings every second. If your application is for green house CO2 control, no initial setup is needed. In the condition of operating environment change (ex. from high to low temp.), it takes 30 sec to respond for CO change.
- Page 7 and minimum values on the displayed chart. While you press down key to change the chart time scale, these value update as well. Display Backlight By pressing any key can activate the backlight for 30 seconds to help you operate in dark environment. Auto Detect Day/Night In greenhouse application, CO2 control is not necessary while light is weak.
- Page 8 while users pick up “ Human” mode in advanced setting. You can check from display to know the existing setting is Human or Plant In Human mode, if the Set Center is 1200ppm, and the Set zone is 400ppm, the output power will turn on when CO2 over 1200+(1/2)*(400)=1400ppm, and shut off when CO2 is below 1200-(½)*(400)=1000ppm.
- Page 9 SETUP Hold key under normal mode to enter MENU setup mode. Press key to choose the necessary MENU setup function and then press ENTER enter. To exit setup, press key four times MENU till it returns to normal mode. “Center”, “Zone”, “Re-CALI”, “ADV”...
- Page 10 Note: One short cut for users to revert the Center and Zone to 1200& 400ppm : In normal mode, press for 3 secs ENTER till an audible beep and LCD should show “ Back Home Done” . RE-CALI While the accuracy of this device is a concern, you may use this function to calibrate this device with outdoor fresh atmospheric air in ~400ppm condition.
- Page 11 ADV(advance) The last function in setup mode is called advance setting which allows you to customize your controller with more flexibility, includes: 1. buzzer alarm on/off, 2. CO2 altitude (pressure) compensation,3. choose relay output to Human or 4. Plant mode, 5.restore to factory default status.

Page 12: Troubleshooting
TROUBLE SHOOTING ? Can’t power on Check whether the power is well plugged. Check whether the fuse is damaged ? Slow response Check whether the air flow channels on the sensing probe is blocked. ? CO2 reading is “Hi” Means the measured value is higher than 5000ppm. -
Page 13: Warranty
WARRANTY The meter is warranted to be free from defects in material and workmanship for a period of one year from the date of purchase. This warranty covers normal operation and does not cover misuse, abuse, alteration, neglect, improper maintenance, or damage resulting from leaking batteries. -
