Parameter configuration
The transmitter can be adapted to fit perfectly into any application by adjusting the software parameters. The parameters are
set with the operation terminals OPU-S. The OPU-S may also be used as remote indicator. For correct display version 1.4 of
OPU-S is required.

Error messages shown on OPU-S
Err1: Communication error: Verify cable connections, cable type and maximum distance.
Err2: CO2 sensor error: Make sure the sensor is not miss-calibrated. If possible, make a 0-ppm or 400 ppm calibration. (See
below). Make sure JP3 is removed or placed in middle position (2-3).
If error cannot be removed by calibrating the sensor, replace product.
Use as P-controller
The CO2-transmitter may be converted into a Proportional fresh air controller through a simple change of two parameter
settings:
Set a minimum concentration when the fresh air fan should start to run at its minimum speed, for example 500 ppm. Set this
as the minimum value in IP03 parameter. Then define the value when the fan should run at full speed, for example 1000 ppm
and set this value in IP04. Your transmitter has now been converted into an air quality P-controller!
The fan will start to run if the CO2 concentration is higher than 500 ppm. It increases to its maximum when CO2
concentration reaches 1000 ppm.
