7.5 Application example 5
The speed of a fan motor shall be controlled with the help of the integrated PID controller to keep the CO2
equivalent of the CO2 / VOC sensor / ventilation demand processor high via the signal output.
− Adjust the fixed setpoint (50 % corresponding to the CO2 equivalent of 1000 ppm)
− Switching on / off via digital input 1
− External alarm to digital input 2; in the event of an alarm, the fan will be stopped
− Booster function via digital input 3 (rpm = 100 %)
− Error message via relay output 1
− Indication of operation via relay output 2
