Error messages shown on OPA-S
Error
Description
Err 1:
Communication error: Verify cable connections, cable type and maximum distance.
Err 2:
Temperature sensor error (element damaged or missing)
Err 3:
CO2 sensor error: Make sure the sensor is not miss-calibrated. If possible, execute 400 ppm calibration. (see
section "Calibration" on page 8).
If error cannot be removed by calibrating the sensor, replace product.
Use the CO2-Transmitter as P-Controller
The CO2-transmitter may be converted into a proportional fresh air controller through a simple change of two parameter
settings:
1.
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 the IP 08 parameter.
2.
Then define the value when the fan should run at full speed, for example 1000 ppm and set this value in IP 09.
Your transmitter has now been converted into a P-Controller!
By using the analog output, 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.
