CO2 Mode
PPM Up: Increase the CO2 ppm if using the CO2 generator or CO2 regulator and compressed
CO2 tank.
Fuzzy Logic: Increase the CO2 ppm if using CO2 regulator and compressed CO2. This mode
applies fuzzy logic control to the CO2 output. Not for use with CO2 generators.
EXAMPLE:
PPM UP: using CO2 ppm with CO2 generator or CO2 regulator and compressed CO2 tank.
Fuzzy Logic: If using CO2 regulator and compressed CO2. This mode applies fuzzy logic control
to the CO2 output. NOT for use with CO2 generators.
Output
LED lit when the CO2 device is active.
After determining CO2 ppm set-point and the CO2 mode, install your desired CO2 generating
device (CO2 generator or CO2 regulator).
