LCD Display

Trend Chart Display

The below chart displays the past readings for any of the three parameters (CO2/RH /TEMP). There are 4 modes that can be toggled by using key: CO2, TEMP, RH, and Cycle(automatically cycles through CO2/TEMP/RH).

Below is a table that shows the available Zoom Levels for all parameters CO2/RH/ TEMP, as well as the duration of each division for corresponding Zoom Levels:

Max/Min

At the top right corner of the display, there are two numerical indicators: MAX and MIN. 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(CO2, RH, and TEMP).

Main Menu Functions

The Main Menu functions can be activated by pressing  . Pressing / once will bring up the main menu, with an underlining flashing bar indicating the current choice.

To select the function, press Press when it is underlined by the flashing bar. Note that after 30 seconds if nothing is pressed, the Main Menu will disappear and the device will revert to the normal state.

Wait till the CO2 reading is stable, and follow the above steps for calibration. After calibration leaves it 10 minutes before normal use.
ºC/ºF
	Use this function to toggle between Celsius ( °C ) and Fahrenheit (°F ) for the temperature display.
ADV
	Use this function to set high and low alarm values of human mode (0) as well as the first option of plant mode (1). High and low alarms for options 2-9 under plant mode are not adjustable. See details in Page 14. (Appendix)
