Section D
- Maintenance
Very little maintenance is required and is really limited to keeping all equipment clean, dry
and cool. Observe and double check all readings from time to time to ensure that sensors
are still accurate. This is particularly important for the CO
2
sensor.
Calibration of CO
2
sensor
SOFT CALIBRATION
–
allows calibration against an accurate CO
2
sensor or known CO
2
level
.
On the IntelliClimate:
Menu > Configure > CO
2
> Enviro 1 (or 2) > CO
2
Scale Factor
Use the up or down arrows to change the scaling away from the normal 100% until the
scaled or calibrated CO
2
reading below the box is correct, press
“
Save
”
to store the new
calibration. When doing this, the percentage change needed is displayed on the screen.
The normal percentage is 100%. If this ever needs to be set below 50% or above 150%
this may indicate some deterioration of the sensor. In this case first try the hard
calibration below to see if that corrects the reading. If not, you may require a new CO
2
module.
HARD CALIBRATION
–
Allows the sensor to self-calibrate when placed in fresh air at
ambient CO
2
levels. As this is less convenient than the SOFT calibration mentioned
above, it is suggested that this is carried out only once per year.
Place the sensor box outside in fresh air and connect to an IntelliClimate controller. On
the IntelliClimate:
Menu > Configure > CO
2
> Enviro 1 (or 2) > Open-Air Calibration
On pressing start a new screen with a timer counting down from 11 minutes will appear.
During this time leave the EnviroSensor in fresh air and avoid breathing near it. It will
self-calibrate to the ambient CO
2
level. At the end, navigate back to the software
calibration screen “
CO
2
scale factor” and set this to 100%.
