Operating Instructions
Initial Setup : When first unboxing, plug the piggyback into the power socket. If successfully connected, 3 things will happen while booting up:
Buzzer beep one time
Chart display shows the current software version & “Warm Up”
Main display shows a countdown from 10
Once the countdown is complete, your product is ready to use. No initial setup or calibration is needed.

CO2 , Set center, Set zone Readings
The device has three built-in main parameters: ambient carbon dioxide(7), Set Center value (6), and Set Zone value(5). They are constantly displayed on screen.
Trend Chart Zoom
Below is a table that show the available Zoom Levels for all parameters CO2, as well as the duration of each division for corresponding Zoom Levels:
Using DOWN will toggle the available Zoom Levels for each parameters. Note that in addition to the Zoom Levels for each parameter, there is an option that will automatically cycle between the Zoom Levels. This can be achieved just by pressing DOWN until icon(8) appears at the bottom left of the chart.
Max/Min
At the top right corner of the display, there are two numerical indicators: Max (2)and Min (3). As the Zoom Level is changed, the Max and Min values will reflect the maximum and minimum values on the chart of the selected parameter. At startup, the unit will automatically display values for 1d (day) value.
Auto Detect Day/Night
The built-in Photo-Cell sensor can automatically detect whether it is Day or Night.It can override the CO2 control and shut off the CO2 generator by turning off the output power during the night.Conversely, if the Photo-Cell detects light and the CO2 level is low, the device will start the CO2 generator by turning on output power.
Output Control
Output power is on when CO2 concentration is over Set Center+(1/2) Set zone, and off when CO2 concentration is below Set Center-(1/2) Set zone. For example, if the Set Center is 1200ppm, and the Set zone is 400ppm, the output power will shut off when CO2 over 1200+(1/2)*(400)=1400ppm, and power on when CO2 below 1200-(1/2)*(400)=1000ppm.
