Fuzzy Logic CO2 mode
“Fuzzy Logic” CO2 mode
allows the user to more precisely
control the CO2 levels inside the growing area. Fuzzy Logic
works by monitoring the rising or falling CO2 level and reacting
to it by quickly activating ON / OFF the CO2 solenoid valve.
This function can ONLY
be used with compressed CO2.
Fuzzy Logic mode can be activated or deactivated by pressing
Enter/Reset and holding for 5 seconds. Press Up or Down to
select generator mode (
gEnErAt
) if using CO2 generator or
Fuzzy logic mode (
LogIcon
) if using compressed CO2. Press
Enter to accept new setting.
Note* To prevent the CO2 regulator from “freezing” or not
closing when using the “fuzzy logic” mode, we recommend
using the Growop CO2 regulator designed to work with the
GrowOp controllers.
Note: Do not use Fuzzy logic mode if operating a
CO2 generator!!!

“HOW TO calibrate” CO2 PPM
1) Place the controller outdoors in a shaded area. Do not
place in direct sunlight. Keep away from people, animals and
other CO2 emitting areas.
Note: If calibration will be in a high traffic (vehicles)
area or a highly populated area a slightly increased
calibration to around 400-475 PPM is recommended.
3) Plug in the controller and allow to “warm up” for a minimum
of 30 minutes. For best results, allow to “warm up” for an hour
or longer.
4) Press Calibrate CO2 PPM to activate the automatic
calibration. The new CO2 level (
380_PP
) will be displayed.
Press the up or down button to change the calibration setting.
DO NOT exhale or breathe on the unit while activating the
calibration function.
5) Press Enter / Reset to start the calibration sequence,
(
Co2_CAL
) will be displayed. Leave controller alone for about
10 minutes.
6) When calibration is complete the display window will return
to normal display and functions. Place the sensor back into
the grow area. All other functions remain as they were prior to
calibration.
