Description
Choose your desired CO2 parts per million(PPM) level and the controller will automatically maintain that specified CO2 level. A built-in photocell located on the remote sensor automatically deactivates CO2 injection during the night time. A remote sensor with 16′ cable allows close placement to the plant canopy.
In the night mode: The controller will always turn off the output of CO2 device.
In the day mode:
A)If the fuzzy logic is off the unit will OPEN the output of CO2 device when the current CO2 value is less than the setpoint. The unit will CLOSE the output of CO2 device is the current CO2 value is greater than the CO2 setpoint plus dead band value.
If the fuzzy logic is on, the unit will fully OPEN the output of CO2 device when the current CO2 value is much lower than the CO2 setpoint. When the current CO2 value is close to the CO2 setpoint, the unit will use fuzzy logic function and sent the PWM (Pulse Width Modulation) signal to control the output of the CO2 device. The PWM cycle is 5 seconds.
