Carbon Dioxide (Co2) - Agrowtek GrowControl GCX Instruction Manual

Carbon Dioxide (CO2)

CO2 controls are used to operate CO2 valves, burners and exhaust equipment based on a carbon dioxide in-
tensity set point and sensor reading. A setpoint determines the target CO2 concentration and a "deadband"
determines the allowed drift from the target before activating the CO2 control.
Example uses:
• CO2 valves / burners
• Exhaust fans
• Alarm horn / strobe

1. Mode Exhaust:
Inject:
2. Sensor CO2 ppm sensor input to evaluate the set point against.
3. Setpoint The target sensor value to achieve.
4. Deadband The allowed drift from the target before activating the function.
5. Dark Switch Disables injection when the CO2 sensor unit detects the ambient light level is 0.
6. Preview A preview of the function settings.
NOTE
When configuring a CO2 control for injection, ensure the function is set to inject during the day period only.
CO2 augmentation should only occur during the day photoperiod.
To coordinate CO2 control with the day photo period, either:
• Turn on the "Disable when Dark" switch to disable when the CO2 sensor detects the ambient light level is 0.
• Set the function time schedule to the lighting or other schedule time.

Function activates when CO2 concentration exceeds setpoint.
Function activates when CO2 concentration is below setpoint.
