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.
