SAFETY NOTICE
CAUTION :
SULPHUR VAPORIZATION CAN DAMAGE YOUR CONTROLLER!
In order to protect and ensure a long life to your CO2 controller, it is very
important TO DISCONNECT AND COVER THE CONTROLLER (placing a
plasc bag around the unit) WHILE USING SULPHUR VAPORIZERS IN YOUR
GROW ROOM.
Grozone is able to detect CO2 sniffers that have been contaminated by
sulphur and we reserve the right not to repair these defect units under
warranty. However, we are able to repair your unit at a reasonable cost
in a mely manner.

Step 1
Connecng the equipment
Securely mount controller on a wall at plant level.
Connect one end of the detachable power cord into a 120 V outlet and the
second end into the power input connector on the le side of the
controller .
The controller warms up for 30 seconds before displaying a valid CO2
reading.
Plug the CO2 generator into the 120V outlet also on the le side of the
controller .

Step 6
Seng high temperature limit
Click knob and rotate to set high temperature limit from 21°C to 49°
C (70°F to 120°F). Default is 35°C (95°F), displayed as H 35 (H 95).
To disable the high temperature shut-off funcon, turn knob clock-
wise beyond 49°C (120°F) unl « OFF » appears on screen.
INSTALLATION & OPERATION
End of sengs
TO EXIT and RETURN TO NORMAL OPERATION, click knob TWICE.
TO CALIBRATE THE CO2 SENSOR, click knob only ONCE and refer to the
instrucons on next pages.
Controller Operaon
Your controller is set and ready to operate when the top 3 light indicators
are off. According to selected operaon mode, the controller will either
exhaust CO2 from or inject CO2 into your grow room and maintain the CO2
level between the user defined high and low limits (steps 2 and 3).
When using a gas burner as CO2 generator, you are likely to experience high
temperature condions that can damage your crop. With high temp shut-
off funcon enabled, the controller will defeat the burner if room tempera-
ture reaches the high temperature limit (step 6). CO2 Operaon resumes
automacally when room temperature cools down by 3°C (5°F).
Displaying actual CO2 and temperature: in order to switch between
actual CO2 and temperature values on screen, rotate knob clockwise
for temperature or counter clockwise for CO2.

IMPORTANT NOTICE:
This step is not required for a new unit (factory calibrated). Verify CO2 sen-
sor precision by exposing your unit to outdoor air every 6 months (correct
value stands between 300 and 500 ppm).
If you need to calibrate the sensor, please follow these instrucons. At any
me before the last step, the calibraon procedure may be cancelled,
causing the controller to return to normal operaon.
CO2 SENSOR CALIBRATION
Steps
IMPORTANT : Before beginning the calibraon , bring the con-
troller outdoor (fresh air being use as a reference) and wait un-
l the reading is stable (2-3min). If the value on the screen is
around 350 to 450 ppm, YOU DO NOT NEED TO RECALIBRATE
YOUR UNIT.
1 Click knob repeatedly unl "Set-Up & Cal" indicator turns ON.
2
Press knob and keep it pressed for about 5 seconds, unl "Set
Up & Cal" light indicator begins to flash and "CAL" appears on
screen.
3
Let knob go, "CO2" and "CAL" appears on the screen alternately
(blinking).

Click knob again, then "CAL" and "400" appears on the screen al-
ternately (blinking).
5
TO CALIBRATE: press knob and hold at least 5 seconds, unl "CAL"
shows up on the screen (not blinking), then let knob go.
IMPORTANT : If you "click" the knob without holding for 5
seconds, you will exit WITHOUT calibrang.
6
The calibraon process only takes a few seconds. When complet-
ed, "CAL" and "GOOD" appear on the screen alternately (blinking)
for 5 seconds, then the controller returns to normal operaon.
IMPORTANT : You MUST see "GOOD" on the screen at the end of
the calibraon process. If not, the calibraon has FAILED. You
need to go back to step 1.
