OPERATING INSTRUCTIONS

Initial Setup: When first unboxing, plug the piggyback into the power socket. If successfully connected, three things will happen while booting up:

1. Alarm will beep once.
2. Chart display will show the current software version & “Warm Up.”
3. Main display will show a countdown from 10.
   Once the countdown is complete, your product is ready to use. No additional setup or calibration is needed.

1. CO2 Trend Chart
2.  AVG HI Reading of Chart
3. AVG LO Reading of Chart
4. Audible Alarm On/Off
5. Target Low Value
6. Target Hi Value
7. CO2 Reading
8. Zoom Level of Time – indicates the chart’s timespan
9. Target Zone Indicator

CO2 / SET TARGET HI / SET TARGET LOW
The device has three built-in main parameters: ambient carbon dioxide (7), Set Target Hi value (6), and Set Target Low value (5). They are constantly displayed on screen.

TREND CHART ZOOM
Below is a table showing the available Zoom Levels for all CO2 parameters, as well as the duration of each interval for corresponding Zoom Levels:

The DOWN button will toggle the available Zoom Levels for each parameter. 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 by pressing DOWN until icon (8) appears at the top of the chart.
AVG HI / AVG LO
At the top right corner of the display, there are two numerical indicators: AVG HI (2) and AVG LO (3). As the Zoom Level is changed, the AVG HI and AVG LO will reflect the average high and average low 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 photocell sensor can automatically detect whether it is Day or Night. The green back lit display automatically turns off during the night period. If a button is pressed during this time the green back light will display for 30  seconds. In Greenhouse (Increase) mode it can override the CO2 control and shut off the CO2 generator or regulator by turning off the output power (CO2 Equipment socket) 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 the output power (CO2 EquIpment Socket). In Vent (Decrease) mode, Photo-Cell status does not affect the output power (Exhaust Fan socket) ON or OFF.
GREENHOUSE (INCREASE) CONTROL
This CO2 controller can be set for Greenhouse mode application by S5 ADVANCE Mode setting. CO2 Equipment socket is on when CO2 concentration is below Set Target Low. For example, if Set Target Low is 1000ppm, and the Set  Target Hi is 1400ppm, the output power will shut off when CO is over 1400ppm and power on when CO is below 1000ppm.

VENT (DECREASE) MODE CONTROL
This CO2 controller can be set for Vent mode application by S5 ADVANCE Mode setting. Exhaust Fan socket is on when CO2 concentration is over Set Target Hi, and off when CO2 concentration is below Set Target Low.

HOLD HOME
To revert to start-up settings at any point, hold ENTER for 3 seconds until you hear audible beep. The device will then revert to Home Setting, as if the power was reset, displaying “Back Home done.” Note that this is not the same as Restore to factory settings.
To clear all stored data in the chart you must Restore to factory settings. To use Restore mode select the Advanced Setting function and hold ENTER for 3 seconds until an audible beep sounds.
Below is a table showing what main menu selection is made by pressing MENU multiple times as well as their functions. Note that the device will display “Done,” followed by the confirmed selection if selected correctly.
MAX / MIN
From the home screen, press ENTER. The trend chart will be replaced by “MAX,” and the maximum value will be shown in the main display area. Press ENTER again to view the minimum value. Press ENTER once again to return to the  home screen.
Note that after 10 seconds if ENTER is not pressed, the device will return to the home screen.

MAIN MENU FUNCTIONS

The Main Menu functions can be toggled through by selecting the MENU button. If the main menu is not selected, the menu LED will remain off, leaving the UP buttons to toggle Zoom Levels, respectively.

• S1 Set Target Hi
• S2 Set Target Low
• S3 Home
• S4 Re-Calibrate
• S5 Advance Setting

Pressing MENU once will bring up the menu LED, with flashing before the current choice. To select the function, press ENTER when menu selection LED is flashing. Note that after 1 minute if nothing is pressed, the Main Menu LED will
shut off and the device will revert to the normal state.

plant. Once Set Target Hi is selected (by pressing ENTER), use either UP or DOWN to increase or decrease the Set Target Hi value. Press ENTER one more time to confirm.
Note that the default value of Set Target Hi is 1400ppm.
52 Set Target Low| Set Target Low value is preset to 1000ppm for general plant. Once Set Target Low is selected, Use UP and DOWN to increase or decrease the Set Target Low value. Press ENTER to confirm.
Note that the default value of Set Target Low is 1000ppm.
53 Home| This is for basic indoor gardening, and cannot be adjusted. Once selected, the Set Target Hi value is fixed 1400ppm, and Set Target Low value is fixed 1000ppm.
S4 Re-Calibrate| Use this function to calibrate your device with outside atmospheric CO2 level — 400 ppm. Select this mode, hold ENTER for 3 seconds until a beep and the chart will read “Calibrating.” To ensure the accuracy of calibration result, place the device outside for 20 minutes before calibrating. To escape, press MENU.
Make sure the device is far from a source of CO2, not in direct sunlight, and not exposed to water. Step away from the unit during calibration.
55 Advance Setting| This function rotates through four options when selected:
• Audible Alarm On/Off
• Altitude Setting
• Work Mode Setting
• Restore Factory Setting
Restore Factory Setting will reset the device to factory settings and erase all stored data in the chart. To use Restore mode, hold ENTER for 3 seconds until an audible beep.

APPLICATION MODE SETTING

Press MENU, then select S5 ADVANCE SETTING function. LCD will show “Mode Setting.” Press UP, and then press ENTER to enter mode setting function. Press UP or DOWN to switch to Greenhouse mode or Vent mode. Press ENTER to confirm.
