Co 2 Injection - Agrowtek GrowControl GC-Pro Operation Manual

CO Injection
2
CO augmentation is controlled via a day-time ppm concentration set-point and the readings from the CO
2
dioxide is not injected during the night time.
CO2 Set Point
ppm
Day Mode
CO2 Reading
Day ppm: Enter the target CO
Dead-band: CO2 ppm drop below ppm set-point before re-
activating CO .
2
Example: Set point = 1000ppm, dead-band = 100ppm; Controller
activates CO output at or below 900 and turns off at 1000.
2
Output#: Enter the output number that the CO
controlled is connected to.
See "Interrupts" under "Output Controls" for disabling CO
and humidity limit functions to cancel CO2 in anticipation of ventilation or to prevent combustion generators from operating
above a set limit temperature or humidity.
Touch Panel
The CO controls are accessed from the "Controls" menu by touching the "CO2" button. Select between injection and
2
ventilation controls.
Press "CO2" button to access the CO
controls.
CO Boost Timer
2
CO Boost Timer allows the standard ppm set-point to be over-ridden by a "boost" (or starvation) set-point for a period of
2
time. Simply set the time band in which the over-ride should take place and the desired ppm set-point during that period.
Boost ppm: Enter the target CO
the standard set-point. When the boost timer period has ended, the CO2 set point will return to the standard set point.
