sensor
Important Notice : This step is not required for a new unit (factory calibrated).
Verify CO2sensor 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 instructions. At any time be-
fore the last step, the calibration procedure can be cancelled, causing the controller to
return to normal operation.
WARNING : Each zone sensor
must be calibrated separately
IS CALIBRATION NEEDED? First select
zone #1 or #2, then expose the corresponding
remote sensor to outdoor air for a minimum
of 5 minutes, fresh air being used as a refer-
ence. If the value on screen is around 350 to

TROUBLESHOOTING
1– BEFORE STARTING
***** CAUTION : MAKE SURE TO READ AND FOLLOW THESE INSTRUCTIONS
BEFORE STARTING THE TEST.
• PLUG both output boxes (Zone #1 Output and Zone #2 Output) to the main module using the
2 telephone cables (included)
• PLUG both remote sensors (Zone #1 Sensor and Zone #2 Sensor) to the main module using
the 2 “Network – CAT5” cables (included, 25-ft each).
• PLACE both remote sensors close to each other in order to read similar (or equal) CO
2
PPM
levels.
• CONNECTA LOAD (lamp or fan…) into the CO
2
OUTPUT BOX of ZONE #1 (NOT in the
OUTPUT BOX of ZONE #2).
• LIGHTING CONDITION: make sure to perform this test in a room with enough light for the
controller to detect a DAY condition. A dark location should be avoided.
2-TEST
STEP HANDLING AND TEST
DESCRIPTION EXPECTED RESULTS
1 Plug the external supply into any
120V outlet or power bar, and plug
the power supply connector on the
left side of the module.
VERY IMPORTANT NOTICE :
MAKE SURE TO USE A 12V – 1A
POWER SUPPLY.
The screen shows a 30-second countdown after a short
introduction displaying the name of the product and
the revision number. Wait until the countdown ends.
12
VERY IMPORTANT NOTICE
You MUST use a
12 Volts - 1 Amp.
Power supply.
A 500mA (or 0.5 Amp.) unit
will NOT supply enough power to
the Controller and Sensors.

TROUBLESHOOTING
2 Turn the KNOB CCW to see
the CO2 PPM level of Zone #1.
Turn the KNOB CW so see the
CO2 PPM level of Zone #2.
Zone #1 or Zone#2 light indicators turn on alternately,
according to the selected zone.
A « normal » CO
2
value should stand between 400 and
1000 PPM. It might be higher if your room is not
ventilated enough or many people are present or you are
blowing directly toward the module.
Both PPM values SHOULD NOT be separated by more
than 150 PPM. If the difference between sensor values
goes beyond 150 to 200 PPM, it is likely that one sensor
needs to be calibrated.
Make sure to select Zone #1 while ending this step.
Zone #2 will be tested later.
CO
2
CALIBRATION will be checked at step 10.
3 Click knob once.
Turn knob both ways, and set
value to 4500 ppm.
The CO
2
High (ppm) indicator lights up to indicate the
value on screen is the CO
2
high setpoint (the default value
is 1500 PPM). The value on screen goes up or down ac-
cording to the knob rotation direction. To complete this
step, set the value to 4500 PPM, getting ready for step 5.
4 Click knob FOUR TIMES The CO
2
Low (ppm) indicator, as well as the 24-hour
Log, Calibration and Setup & Cal indicators, will light
up in this order. Make sure to stop when Set-up & Cal
lights up.
5 Turn knob in both directions to
change the value on screen be-
tween F13 and F14 repeatedly
The ZONE #1 OUTPUT indicator will turn off when F14
is set, and will turn back on when F13 is set. The LAMP
(or LOAD) and the Zone #1 Output indicator always turn
ON and OFF at the same time.
This step works only if the CO
2
High (ppm) has been set
to 4500 PPM at step 3.
6 Turn the knob to set value to
F11 Click knob ONCE to exit The 5 last light indicators at (from CO
2
High (ppm)
to Set-up) must be off to view the CO
2
level in Zone #1.
F11 stands for « CO
2
enrichment – day only ». The ZONE
#1 OUTPUT indicator must be ON.
7 Place the Zone #1 sensor flat on
your desk and cover it up en-
tirely with a DARK FABRIC
(coat, sweather…).
WARNING: the sensor has two
daynight detectors, one on
EACH SIDE of the enclosure.
The Zone #1 Output indicator must be ON before you
hide the sensor, but will turn off after 6 to 8 seconds when
the night condition is detected.
8 Remove the fabric covering the
Zone #1 sensor and wait 6-8
seconds.
The Zone #1 OUTPUT indicator will turn ON when day
condition is detected.
13

The basic test for Zone #1 or Zone #2 is now complete. If you just ended Zone #1 test, please do
again STEP3 to STEP9 while replacing « Zone #1 » by « Zone #2 » in the text.
PLEASE WAIT UNTIL CO2 PPM LEVEL GOES DOWN BELOW 1500 PPM BEFORE
STARTING THE TEST ON ZONE #2.
The CO
2
SENSOR (SNIFFER) CALIBRATION instructions follow.
TROUBLESHOOTING
9 Blow softly on Zone #1 sensor You will see the CO
2
PPM level on screen going up
to a value up to 5000 PPM and above. If needed, blow
closer to the module or stronger : your breath contains
a lot of CO
2
.
The Zone #1 OUTPUT indicator must turn OFF and
the screen will show « OVER » and « 5000 »
alternately.
10 Check the CO
2
Controller calibration
to confirm whether calibration is
required or not.
IF REQUIRED, you will find the
calibration procedure on next page.
You must bring the sensor close to an open door or
window or simply outside. Wait 1-2 minutes to get a
stable value and AVOID breathing near the sensor.
The CO
2
PPM value on controller screen should
be between 350 and 450 PPM, sometimes up to 500
in urban surroundings. In this case, your module
DOES NOT NEED calibration.
Note : The CO
2
sensor (sniffer) is precise to +/- 75
PPM (industry standard) meaning that two or more
modules in the same room are likely to indicate differ-
ent ppm values, showing variation between them of
up to 150 ppm. THIS IS NORMAL and no action is
required. If the variation between readings is beyond
150-200 ppm, one of them is likely to require a cali-
bration. Be aware that a difference of 100 PPM has
insignificant effect on plants.

REMOTE SENSOR CALIBRATION
STEP
>>>>>IMPORTANT<<<<<
Expose your sensors to outdoor air for a minimum of 1-2 minutes, fresh air being used
as a reference. If the value on screen is around 350 to 450 PPM, YOU DO NOT NEED
TO RECALIBRATE YOUR UNIT.
1 Turn knob to select the first zone sensor you would like to calibrate ( Zone #1 or Zone #2 indicator will be ON accordingly).
2 Click knob repeatedly until “Calibration” indicator turn ON, then controller screen
shows « CO2 ».
3 Press knob and keep it pressed for about 5 seconds, until « CAL» appears on screen.
4 Let button go, « CO2 » and « CAL » appear on screen alternately (blinking).
5 Click knob again, then « CAL » and « 400 » appear on screen alternately (blinking).
IMPORTANT : if the value shown IS NOT 400, turn the knob to set value to 400.
6 TO CALIBRATE : press knob and keep it pressed for at least 5 seconds, until « CAL »
shows up on screen (not blinking), then let button go.
IMPORTANT : if you “click” the knob instead of “pressing and maintaining the
knob pressed”, you will exit WHITOUT calibrating.
7 The automatic calibration takes just seconds. When completed, « CAL » et « GOOD »
appear on screen alternately (blinking) for 5 seconds, then the controller returns to
normal operation.
IMPORTANT : you MUST see « GOOD » on screen at the end of the calibration
process. If not, the calibration has FAILED. Then go back to step 1.
8 Turn knob to select the second zone sensor you would like to calibrate (Zone #1 or
Zone #2 indicator will be ON accordingly) and then do again STEP 2 to STEP 7.
