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 CO2control and shut off the CO2generator by turning off the
output power during the night. Conversely, if the Photo-Cell detects light and the
CO2level is low, the device will start the CO2generator 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 CO2concentration 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
CO2over 1200+(1/2)*(400)=1400ppm, and power on when CO2below 1200-
(1/2)*(400)=1000ppm.
