Mounting
CO2RT-R / CO2RT-R-D should be mounted in a location with good air
circulation where they can be expected to give a representative reading.
Mount the sensor on a wall-box or directly on the wall. Remove the front
cover by depressing the locking tounge in the lower part of the casing
using a 3 mm flat-blade screwdriver (see arrow in figure). Press and twist
the screwdriver at the same time as you pull the bottom part of the front
outwards. When the bottom end of the front is free from the casing bottom
part, slide the cover towards the top of the casing to free the hooks hold-
ing the upper edge of the front cover.

Start-up
After applying power to the sensor, it will take a few minutes before it
shows correct values.
Calibration
CO2RT-R / CO2RT-R-D are factory calibrated before delivery and do
not need to be calibrated at installation.
CO2RT-R / CO2RT-R-D are calibrated automatically, which means
that manual recalibration is not required during the lifetime of the
sensors.
