ControlsFigure 18 - P1 to P5 jumper configurationCO2CO2VOCThe CO 2 option allows to measure aCO 2 (or CO 2 and volatile organiccompounds) in order to increase ordecrease the fresh air amount in thebuilding.The CO 2 /VOC sensor providessensing of carbon dioxide over arange of 0-2000ppm converted to avoltage signal from 0-10Vdc. Thissignal is converted in the resistanceoutput module (ROM/UEM) to aresistance value (64 stages of3.12 ohms) from 0-200 ohms tocontrol the minimum openingposition of a damper of theeconomizer or the damper of a0-50% motorized damper.Figure 19 - CO2/VOC adjustmentpotentiometer location1.
